Rhizomarasmius pyrrhocephalus is a taxon of fungus. It serves as the type species of its genus.
The genus Rhizomarasmius was split from Marasmius due to morphological differences such as the cystidia and the rooting stipe (hence the prefix rhizo). [1] Rhizomarasmius pyrrhocephalus is the type species .
The genus name is a combination of the prefix Rhizo, from the Ancient Greek ῥίζα (rhíza, "root"), and the Greek marasmos (μαρασμός; "drying out; withering"). [2]
The specific epithet combines the Ancient Greek pyrrho (πῦρ • pyr; "fire") [3] and cephalus ("head"). [4]
The orange-colored cap is 1–2.5 centimetres (1⁄2–1 in) wide. Its rooted black stipe has velvety hairs [5] and is up to 9 cm (3+1⁄2 in) long. [6] It has adnate gills and a white spore print, [6] not unlike Marasmius species.
It can resemble Marasmius sullivantii , Marasmiellus biformis and M. subnudus . [6]
This mushroom is known mainly from eastern North America, and grows from May to October on leaf litter and wood. [6]
