About Xeromphalina campanella (Batsch) Kühner & Maire
The fruit body of Xeromphalina campanella has a small umbrella-shaped cap, measuring 0.5–2 centimetres (1⁄4–3⁄4 in) wide. As the cap matures, its outer portion expands and lifts, leaving the center slightly depressed in a navel-like shape. The thin brown stalk is 1–5 cm (1⁄2–2 in) long and 1–3 millimetres (1⁄16–1⁄8 in) wide; it is yellow at the apex, reddish-brown below, and covered with brown or yellow hairs at the base. The gills range in color from pale yellow to pale orange. The flesh is tannish and has a mild taste. The spore print of the species is pale buff. Xeromphalina campanella produces fruit bodies that grow in clumps or very dense clusters on decaying coniferous tree logs, stumps, and woody debris. It can be found during any wet season of the year. It occurs across Eurasia and North America, and is commonly found in North America. In some cases, this species can almost completely cover old tree stumps. Some populations of the species are geographically separated and reproductively isolated.
