Rhizomarasmius pyrrhocephalus is the type species of the genus Rhizomarasmius, split from Marasmius due to morphological differences such as the cystidia and the rooting stipe (hence the prefix rhizo-).^[1] It has a 1–2.5 cm (0.39–0.98 in) wide orange colored cap and a long, rooted black stipe with velvety hairs.^[2] Like its original genus, Marsmius, Rhizomarasmius has a white spore print and attached gills. This mushroom is known mainly from North America East of the Rocky Mountains, and grows from Spring to Fall on leaf litter and wood.

Etymology

Rhizomarasmius is derived Marasmius, which comes from comes from the Greek word marasmos - μαρασμός, meaning "drying out; withering". The prefix Rhizo- comes from Ancient Greek ῥίζα (rhíza, "root").^[3] Also coming from Ancient Greek, pyrrho- the word for fire, πῦρ • pyr,^[4] and cephalus meaning head.^[5] All together in English we have a tremendous name of: "The withering rooted fire-head".
