Rhizomarasmius pyrrhocephalus is a taxon of fungus. It serves as the type species of its genus.
Taxonomy
[edit]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.
Etymology
[edit]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]
Description
[edit]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.
Similar species
[edit]It can resemble Marasmius sullivantii, Marasmiellus biformis and M. subnudus.[6]
Distribution and habitat
[edit]This mushroom is known mainly from eastern North America, and grows from May to October on leaf litter and wood.[6]
