Extract from Wikipedia article: Flammulaster erinaceellus is a species of fungus in the agaric family Tubariaceae. It was first described in 1876 as Agaricus detersibilis by Charles Horton Peck. Roy Watling transferred it to Flammulaster in 1967. The fruit body has a hemispherical to convex cap 1–2.5 cm (0.4–1.0 in) in diameter that is covered with small, erect, brownish scales that can be readily rubbed off. The gills have an adnexed attachment to the stipe. The stipe is up to 2.5 cm (1.0 in) long and 2 mm thick. It is either hollow, or stuffed with a pith-like mycelium. The spores measure 7.5–9 by 4–5 µm. Fruiting occurs on logs in the woods.
Polish: Płomienniczek rdzawobrązowy.
Flammulaster erinaceellus is a small to medium-sized, spine-like fungus that grows in clusters or tufts. It has a cap that ranges from 0.5-2 cm in diameter, typically yellow-brown to orange-brown in color with a hairy or fuzzy appearance. The gills are crowded and free from the stem. In East and Central Texas, Flammulaster erinaceellus is commonly found growing on decaying wood, particularly hardwoods like oak and maple, as well as on soil and leaf litter in wooded areas, often in association with mosses and other small plants. It typically fruits from spring to fall, with peak activity during the warmer months.

Spores from a mushroom Flammulaster erinaceellus collected in Little Thicket Nature Sanctuary a day before. Texas, April 23, 2023Observations of the fungus Flammulaster erinaceellus in East and Central Texas show that it grows on rotting wood, specifically pine and oak logs. The mushrooms were found in various locations, including Huntsville State Park, Sam Houston National Forest, and Little Thicket Nature Sanctuary. They were observed growing in groups or singly on fallen trees, branches, and logs, often on completely rotten brown wood. The observations took place over several years, from 2018 to 2023, and during different months, including November, October, and April. Close-up views of the mushrooms show their distinctive powder-scale appearance, while underside views reveal their gills or spore-producing structures. Spores were also collected from a mushroom in Little Thicket Nature Sanctuary, providing further information about the species' characteristics. The fungus appears to thrive in these environments, suggesting a preference for decomposing wood.
