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]

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]
