Yashroom Photography: Fungi of New York Well... MOSTLY fungi (slime molds, too) of New York... but I wanted to keep the title short 😀

I like to take pictures of fungi. Sometimes they come out good.

I like to share their beauty.

Two days ago I posted pictures of Amanita onusta. Here's another species from the same genus: Amanita brunnescens var. pallida.

IT LOOKS SO DAPPER!!

Gray, warty, cute.

Amanita onusta, a.k.a. Gunpowder Amanita, has a very different vibe from the red-and-white cartoon Amanita most people picture. It is usually grayish-white to pale gray, with darker gray-brown warts or patches scattered across the cap. 🔍

Like many Amanita species, it starts life wrapped in a universal veil, a protective outer covering that breaks apart as the mushroom expands. Those leftover veil bits become the cap warts, and the lower stem can also carry shaggy or wart-like remnants.

Amanita mushrooms are mycorrhizal, meaning it partners with trees underground, trading fungal help with water and nutrients for sugars made by the tree. 🌳

The name fits the look. Onusta comes from a Latin word meaning loaded, burdened, or carrying a load, which matches a mushroom covered in chunky gray “baggage.”

For the first day of summer, here's a delicious, juicy raspberry!

Well, not really.

This is (probably) Tubifera ferruginosa, often called red raspberry slime mold. It's a slime mold rather than a fungus. It shows up on well-rotted wood, where its feeding stage eventually transforms into a spore-producing structure.

That “raspberry” look is not one solid blob. It is a cushion-like mass made of many tiny sporangia, which are individual spore factories packed tightly together but still separate.

Color tells the timeline. Fresh fruiting bodies can be red, pinkish, or orange-red, like this one, and then they shift toward purplish brown and finally rusty brown as the spores mature. That rusty stage fits the name, since “ferruginosa” points to rust-colored tones.

Fungal highway! 🛣

The pale, branching strands in this photo are mycelial cords, bundles of fungal hyphae (the microscopic threads that make up a fungus). Instead of sending single threads everywhere, some fungi braid many hyphae together into visible cables.

That cable design is useful because dead wood is patchy. A fungus may have food in one part of a log, moisture somewhere else, and a new branch to colonize a few inches away. Cord-forming fungi can link those patches and move carbon, nutrients, and water through the network. This is fungal infrastructure. The fungus reinforces the routes that matter and abandons routes that do not pay off.

So this photo catches a usually hidden part of fungal life: not the mushroom, but the body plan behind the mushroom. The fruiting body is the billboard. The cords are the roads.

🔥Fiery cap, black leg

Rhizomarasmius pyrrhocephalus is a tiny marasmioid mushroom, the kind of delicate forest-floor fungus most people step past without noticing. It grows on leaf litter and woody debris in hardwood forests. 🪵🍂

The “fire cap” part makes sense right away: the cap is orange to orangish brown, sitting on a long, tough stem that darkens to brown or black and is often densely hairy. That stem can also be deeply rooted into the substrate, like the mushroom is anchored below the leaf litter. That's where "rhizo-", which means root, in the genus name comes from.

This species has excellent timing. It has been described as one of the first gilled mushrooms to appear in spring and one of the last to stop fruiting in fall, which is a pretty good strategy for a small decomposer working the litter layer. 🌧️
