Rhizomarasmius pyrrhocephalus is a taxon of fungus. It serves as the type species of its genus.

Taxonomy

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

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

The orange-colored cap is 1–2.5 centimetres (12–1 in) wide. Its rooted black stipe has velvety hairs[5] and is up to 9 cm (3+12 in) long.[6] It has adnate gills and a white spore print,[6] not unlike Marasmius species.

Similar species

It can resemble Marasmius sullivantii, Marasmiellus biformis and M. subnudus.[6]

Distribution and habitat

This mushroom is known mainly from eastern North America, and grows from May to October on leaf litter and wood.[6]
