Found in a potted Crassula ovata plant.
Pileus surface grabrous.
Lamellae unchanging when bruised.
Spores dextrinoid, (5.3–)5.5–6.3(–6.6) × (3.6–)4–4.6(–4.5) μm, (mean length = 5.87 ± 0.4, mean width = 4.29 ± 0.28, Q = (1.2–)1.3–1.5(–1.6), mean Q = 1.38 ± 0.14).
Basidia 4-spores, (18.4–)19.2–22.6(–22.3) × (7.2–)7.3–8.5(–8.7) μm, (mean length = 20.91 ± 1.74, mean width = 7.92 ± 0.62, Q = (2.1–)2.3–3.1(–3), mean Q = 2.66 ± 0.4).
Pleurocystidia were not observed.

Compared to L. birnbaumii, spores are much smaller, Pileus is glabrous, and color is pale.

Tiny, by anyone's standards. Not easily observed except via enlarged photography. Occurring on Cow Dung that is about (no less than) 8 weeks old.
They are little more that 6-10mm high when mature. They quickly deliquesce once the cap is open. Delicate, silvery stipe with grey, slightly warty, cap
,
It is possible they might be Coprinopsis xenobia

But further microscopic ID by me is impossible. These occur in the sheltered folds of the dung, in partnership with much larger Cheilymenia and the really tiny Pilobolus, each seen in the photos.

Single fruiting body on ground under back deck.

Pileus light yellow (the light yellow does not show well in the images) with a light brown central disk. Cap 3 cm diam, Stipe 4.7 x 0.2 cm with a 0.7 cm bulbous base. Basidiospores (5) 6-7 x 4 (4.5) microm.

This was some sort of fungus or plant growth growing on an oak tree root in the crawlspace of someone’s house. My partner is a plumber and knows I enjoy nature mysteries. he sent me these thinking it was a “dangerous mushroom” 😂 unfortunately this is the only pic he got and didn’t bring a sample home. He says they’re about 2 feet in length each. Some had a “paddle” on the end. My partner did some investigating and poked the root below one of these large growths. It was so brittle and hollow that it just broke straight through(third photo). The second photo looks like a lacquered bracket, and the long coral-like arms almost look like new growths, but on this scale, I’m stumped! I’ve heard of giant ganodermas, but wasn’t expecting to find one in South Carolina? Anyone know what in the world is going on here??
