Extract from Wikipedia article: Xeromphalina cauticinalis is a species of agaric fungus in the family Mycenaceae. Originally described in 1838 by Elias Fries as Marasmius cauticinalis, it was transferred to the genus Xeromphalina by Robert Kühner and René Maire in 1934. It is found in North America, where it fruits in the summer and autumn singly or in groups on the seeds, needles, and sticks of conifers, and sometimes on aspen leaves. The fruit bodies have convex yellowish caps measuring 0.5–2.5 cm (0.2–1.0 in) in diameter supported by a tough yellow-brown to dark brown stipe that is 3–8 cm (1.2–3.1 in) long by 1–2.5 mm thick. The pale yellow gills have a decurrent attachment to the stipe and are somewhat distantly spaced. The spore print is white, while individual spores are elliptical, smooth, amyloid, and measure 4–7 by 2.5–3.5 µm.

Xeromphalina cauticinalis is a small to medium-sized, slender-stemmed fungus with a bell-shaped to conical cap that ranges in color from yellow-brown to reddish-brown. It grows in clusters on decaying wood, particularly pine and oak. In East and Central Texas, it is commonly found in wooded areas, especially in the fall and early winter months, often fruiting in large numbers on well-decayed logs and stumps. The fungus is typically 1-4 cm tall, with a cap that is 0.5-2 cm wide, and has a distinctive fibrillose or powdery appearance on the stem.
