Fantastic Fungi (NFN Fungi Hike, Part 2)

Back in August, I went for a hike with the Norfolk Field Naturalists to search for Fungi to photograph (see Part 1). Along the way, I encountered many organisms both fungal and not-so-fungal.

One non-fungus was photographed perched atop some fungi on a log. The creature was a Marbled Fungus Weevil (Euparius marmoreus), which feeds on polypore fungi (Marshall 2018).

Marbled Fungus Weevil, the only time I used my macro lens on this entire hike.

The next observation brings us back to the focus of the hike: Fungi. This strange spherical object covered in a lacework pattern is the fruiting body of an Earthball (Scleroderma). These fungi actually interconnect with tree roots to form mycorrhizal associations, benefitting the trees and the fungus (Stephenson 2010).

Another spherical object caught our eye while hiking through the woods: an Oak apple gall. This particular one was caused by Amphibolips cookii, a Gall Wasp feeding within the bud of a Red Oak (Quercus rubra). The bud developed into this spherical gall, while the larva fed within and then this “oak apple” detached and fell to the forest floor, and I guess the adult wasp has already left this gall behind? I don’t know, it was very difficult to find any information about this species or gall wasps (Cynipidae) in general despite them being fascinating insects (what I did find was a website that contains some information: gallformers.org, a site worth checking out if interested). I have a particular fondness for galls caused by insects… they’re plant growths that create particular species-specific patterns for the insects that inhabit them… what’s not to like?

Further down the trails, we encountered some classically shaped mushrooms unlike the more bizarre (in my opinion) Earthballs (Scleroderma). A member of the genus Oudemansiella and a member of the genus Russula.

Russula fungi are ectomycorrhizal, meaning that their underground mycelia (the major part of the fungal body) connect with roots of trees and other plants to transfer and exchange nutrients (Stephenson 2010).

Some of the most common fungi that we spotted were associated (as many fungi are) with dead or dying wood. Fungi that feed on dead or decaying material are known as saprotrophs. Orange Mycena (Mycena leaiana) were spotted multiple times throughout our excursion and I have to say they might be my favourite fungi that we found simply for aesthetic reasons. The beautiful colour of their fruiting bodies really brighten up the dead logs and fallen trees in the forest. 

Another wood-feeding saprotroph we found often is known as the “Oyster Mushroom” (Pleurotus), apparently because of its fishy smell (which I couldn’t detect, perhaps it needs to be cooking?). These are very commonly collected for humans to eat.  As mentioned above, the Oyster Mushrooms feed on decaying and dead wood, but they also feed on microscopic creatures called nematodes. The details of the interaction are incredible. The Pleurotus fungi has special cells among its hyphae (the underground components of the fungal mycelium) which produce a toxin that paralyzes nematodes. After contact, the nematodes continue moving (usually much slowed, and erratically) for 30 seconds to several minutes before succumbing to the paralyzing toxin. The immobilized nematodes are then attractive to fungal growth from the Pleurotus mycelium, which produces hyphae that thread through the material (usually dead wood or soil) to reach the nematodes and enter their bodies. These fungal threads break the nematode down, consuming it while it is still alive but paralyzed. If you’re interested in more of these details, you can read the full paper where it’s described (Barron and Thorn 1987) here: https://cdnsciencepub.com/doi/10.1139/b87-103.

There were a couple of other saprotrophic fungi found feeding on logs during the hike. Resinous Polypore (Ischnoderma resinosum) has a strange texture that was unexpected, though appearing like tougher shelf fungi it was actually quite soft and pliable. Our guide likened it to the feel of a donut and I can attest that this assessment is bizarrely valid.

Resinous Polypore, strangely soft and light.

Not all fungi grow on logs however, and there are several interesting groups that are very easy to miss. One colorful but tiny fungus is the Red Chanterelle (Cantharellus cinnabarinus) which grows singly or in clumps and is connected to the root systems of trees in yet another mycorrhizal relationship.

Two representatives of a more bizarre ground-sprouting group would have been easily missed. This group is known as the “Earth-tongues” (Family Geoglossaceae). You can (perhaps unfortunately) see their resemblance to strange tiny tongues protruding from the soil. Our guide was quite excited to have spotted the dark Earth-tongues (identified via iNaturalist as Trichoglossum because of the tiny hairs) because they would be very easy to miss.

That brings us to the end of the fascinating fungi that I spotted on our hike! It is not the end however of the non-fungal sightings. A few more of those to review in the final part of this ‘series’.

Algonquin Observations, Part 1 – Pog Lake Campground

I love Algonquin Provincial Park. There is a special place in my heart for the vistas of trees, lakes and rock that extend to the horizon. Whenever I stay in the park, I encounter new creatures and make new observations, or if I encounter familiar organisms, I often appreciate them in a new light.

The first observation of my most recent trip (over the July/August Long Weekend) was a familiar bird creating a familiar knocking sound as it chipped away at the outer bark of a pine tree. The bird was a Hairy Woodpecker (Dryobates villosus), and its hammering into the edge of a tree is common in Norfolk County as well as Algonquin Park.

The other species of Woodpecker I encountered on this trip was not so familiar, and certainly not a species I could encounter in the more southern parts of Ontario. The Black-backed Woodpecker (Picoides arcticus) has a range across the Boreal Forests of North America, and Algonquin Provincial Park is at the southern edge of its range. They are a species tied to the disturbance of fire, as they mainly feed on insects (such as bark beetles and wood-boring beetles) which increase in population in fire-killed stands of trees (Backhouse, 2005). I observed the female and male of this species (likely a mated pair) foraging on the trees surrounding our campsite, and I also observed the male digging into what must have been a stump (the stump was obscured by vegetation, but I could see the yellow spot on the male’s head as he knocked away from ground level). As just mentioned, the male and female can be distinguished based on the presence or absence of a yellow patch on the head (the male has the yellow patch, the female does not). Not only did I see this species foraging but within the campground at Pog Lake there was actually a nest! Like most Woodpeckers (maybe all, but I’ve learned not to make rash generalizations), the Black-backed Woodpecker creates a new nest each year, carving a hole into a tree to house its young. I could hear the young inside the nest cavity, producing almost continuous begging calls for food. I saw the male drop by to drop off food he had collected, and I also got some pictures of the male on nest-guarding duty, sticking his head out of the nest entrance which was not too much higher than eye level.

The Hairy Woodpecker I first spotted was not the only familiar bird encountered within Algonquin Park. Robins (Turdus migratorius) are a common sight throughout the campground, and the screams of Blue Jays (Cyanocitta cristata) frequently break the solemnity of the sky-stretching Pines. Another vocal bird which is quite common in suburban backyards is the Common Grackle (Quiscalus quiscula). Grackles patrolled through the campground, searching for any scraps of food left out by unwary campers. They may not be everyone’s favourite bird sighting, but I think their metallic blue heads are quite beautiful, and their overall appearance and movements are striking. 

Two birds very much associated with Algonquin Park in my mind (even though I’ve also seen both on the Lynn Valley Trail in Norfolk County) are common ascenders and descenders of trees. The Brown Creeper (Certhia americana) often swirls around a tree trunk as it descends and then begins to work its way up in leaps and bounds, plucking insects and spiders from their secluded hiding places. I wonder if the rapid spiralling descent is some sort of signal to other members of its species (I’ve seen Brown Creepers foraging in pairs, or more than two) or if it’s a way to locate potential prey for their way up.

Brown Creeper… creeping (more like leaping)… up a tree.

The Red-breasted Nuthatch (Sitta canadensis) doesn’t move up and down a tree in the same stereotyped way as the Brown Creeper, and it certainly stands out more from the bark with its attractive white-and-black face, blue back and red breast feathers. Nuthatches are renowned for their ability to walk head-first down a tree rather than up like most other bark-foraging birds (including Woodpeckers, Chickadees and Brown Creepers).

Possibly the most beautiful bird observation in the Pog Lake campground was this Yellow-rumped Warbler (Setophaga coronata). These birds are often migratory through more Southern Ontario, arriving in the coniferous forests of Algonquin in mid-to-late April to breed (Tozer, 2012). According to the Atlas of the Breeding Birds of Ontario (Cadman et. al. 1987), they will breed in coniferous or mixed forests across Ontario (though they are more abundant in the more Boreal regions).

Usually Insects are my focus, and part of the reason for that is their abundance, diversity, and accessibility. Because of the rainy and cool weather for most of my visit, there were not as many Arthropods out and about (at least not as noticeable). A few notables made themselves known however. One striking spider was resting on the side of my car.

A Northern Pearly-eye Butterfly (Lethe anthedon) was resting on someone else’s car and I had to snap a picture.

A very impressive Insect sighting in the Pog Lake Campground came on our last day in Algonquin. I found a massive Northeastern Pine Sawyer Beetle (Monochamus notatus). The Sawyer was very cooperatively still on the cool damp morning, allowing me to get some really great closeups. It was also silent, despite being moved to a more convenient location for photos. That may seem like a strange observation to make, but apparently Longhorn Beetles (Family Cerambycidae, of which Monochamus notatus is a part) make a “squeak”, not with their mouth but with parts of their thorax rubbing together (Marshall, 2006).

Northeastern Pine Sawyer Beetle. I hope you can see why members of this Beetle Family (Cerambycidae) are called Longhorn Beetles.

A few points of interest for this particular Sawyer Beetle. As the image above demonstrates, its antennae were almost as long as the rest of the body which marks it as a female. The males are the ones with the really long antennae, often twice the length of the rest of the body. Here’s a male of the same species to show you what I mean. (photo from wikipedia):

It may be hard to see in my photo above, but these Beetles (including the female I observed) often have invertebrate hitchhikers. From a different angle it’s a bit clearer that my Beetle had a cluster of red Mites on her thorax.

Closeup of the M. notatus I found in Algonquin Park.

These Mites are presumably hitching a ride to dead/dying trees which the Beetle will be seeking (Monochamus beetle larvae feed inside of dead/dying trees). I’m not sure what the Mites will do once there, as Mites are incredibly diverse and have numerous ecologies and life histories and I don’t know what kind of Mites these are. The other interesting thing to note in my closeup picture above is the eye of the Beetle. Notice how it curves around in a crescent shape around the base of the antennae. Just thought that was sort of a strange arrangement for eyes/antennae. One more closeup shot of this Beetle because it was so cooperative:

Closeup portrait of M. notatus.

As I mentioned above, Insects are often what I notice and focus on. During our trip, I couldn’t help but take note of the wonderful beauty and diversity of some of the plant life in Algonquin Park as well. I suffer from “plant blindness” and I have been trying to rid myself of the condition as much as possible (see my book review of Flora of MiddleEarth for more on this subject). So I will end this post with a plant observation (and there will be more to come as I continue to write up my Algonquin observations). Throughout the Pog Lake Campground, there were some beautiful bright red berries amid ground-level green leaves. I found out that these plants are Bunchberry (Cornus canadensis).

Bunchberry Berries (and leaves).

Bunchberry has white flowers which spread pollen via the wind and insects in order to reach other flowers and reproduce (ie. form fertile berries). Amazingly, Bunchberry flowers are equipped with a mechanism to launch their pollen on an insect that triggers them, unfolding their petals at incredible speed to fling pollen onto the insect and up into the air (for possible wind-dispersal of pollen). This truly impressive feat is accomplished in 0.5 milliseconds. To put this into perspective, the Mantis Shrimp has the fastest movement of all Animals, and its record-holding strike lasts 2.7 milliseconds… five times as long as the Bunchberry flower petals take to open (Runtz, 2020). If that doesn’t make you want to pay more attention to plants, I don’t know what will.

Stay tuned… more to come from my trip to Algonquin, including more Birds, more Plants, and more Insects!

A Visit to Big Creek, Part 2

This is the second loop of my journey through the Big Creek Conservation Area Trail. For part 1, go here.

Having returned to the parking lot, I saw some amazing aerial masters. Similar to the Kingfisher and the Black Terns, I saw Barn Swallows (Hirundo rustica) maintaining a single position in the air, this time in groups. They were incredible to watch, and thankfully one landed for a moment so I was able to get a clear photo of it.

Barn Swallow, kindly sitting still for once for a picture.

It was only recently that I realized there were so many different species of Swallows in our area. Later in this same hike I took (very blurry) pictures of two other species: Tree (Tachycineta bicolor) and Northern Rough-winged (Stelgidopteryx serripennis) Swallows.

I saw more Mute Swans, this time sleeping with their elongate necks tucked around themselves. In the picture below, you can really see how bizarre that long neck looks when it’s not extended.

A small brown shape on the path ahead revealed itself as an Eastern Cottontail (Sylvilagus floridanus). Wikipedia says of this animal: “The cottontail prefers an area where it can hide quickly but be out in the open.” This seems to describe my sighting perfectly as the rabbit was fully exposed on the path, but disappeared into the plants at the edges as soon as I neared, and I was unable to spot it again.

One of the only Insect observations I made were some mating Deer Flies (Genus Chrysops). Although they cause pain when they bite and can be determined adversaries, when you get a good look at them you realize they are also quite beautiful. Look at those wonderfully strange eyes and patterned wings.

I had to pass through the Redwing assault again, and once through I saw the rarest observation of my hike. A black dome was crossing the trail at a decent rate for what I quickly realized was a turtle. In my excitement I couldn’t get the zoom lens to focus on the turtle for some reason. As I was trying to get a picture, I rushed forward, hoping to get a good picture of the turtle before it disappeared into the undergrowth that it was making for. While doing this, I startled something to my left. A Great Blue Heron (Ardea herodias) took to the skies, disturbed from its ambush site by the turtle-seeking human. I quickly snapped a couple of pictures of the Heron before moving forward, hoping to still find the Turtle.

After this mutual startling, I made it to the location of the Turtle, which had reached the shelter of the vegetation. I was still able to see the turtle (it was, after all, not moving incredibly fast) and took a few pictures of its shell. From this, I was able to determine that it was a Blanding’s Turtle (Emydoidea blandingii). I have only ever encountered Snapping Turtles and Painted Turtles before, so this was a very exciting sighting for me, even if I didn’t get a good photo.

My clearest shot of the Blanding’s Turtle as it barreled through the undergrowth.

Just a few dozens of meters further I came upon a young deer browsing in the middle of the trail. It still retained the spots of a fawn, and was smaller than an adult but certainly not a helpless baby. The deer seemed pretty unaware of me until I was quite close so I got some good pictures as it looked at me and after it saw me it wandered off into the marsh.

I could hear Marsh Wrens all around making their buzzing calls, but they are extremely difficult to spot and even more difficult to capture with the camera. This was one of my closest attempts, it’s almost as though the Wren is mooning me with its upright tail sticking out into the line of my camera instead of its chirruping face:

Most times in the summer, I have the Macro lens fixed to my camera because of the abundance of insect life, but on this trail I kept the telephoto equipped for all of the bird sightings I had. Near the end of my walk, I came upon a Dragonfly perched on the ground of the path and I was able to capture it adequately with the telephoto. It was A Blue Dasher Dragonfly (Pachydiplax longipennis), which occurs throughout most of the United States but only in the very Southern portions of Canada.

Ahead of me, meandering along the trail, was a pair of young Canada Geese (Branta canadensis). They were interesting to me, because they weren’t the Goslings following their parents and they weren’t Adult size either. The one appears to be much more “gosling-like’ than the other, which has started to acquire the characteristic facial markings of adult Canada Geese.

My final farewell to the trail this day was seeing a Heron stalking in the shallows, wreathed in fog. This Heron of the Mists was a perfect sendoff to my journey through the Long Point wetlands.
