Mitrulinia

Mitrulinia is a fungal genus of uncertain familial placement in the order Helotiales. Mitrulinia is a monotypic genus,^[2] containing the single species Mitrulinia ushuaiae. The genus was circumscribed in 1987 by mycologist Brian Spooner.^[3]

Mitrulinia populations have been found separately in Argentina and on the South Island of New Zealand.^[4] Spores or hyphal fragments were also found present in snow on Livingston Island, Antarctica.^[5] Individuals found in New Zealand are thought to belong to a novel species rather than Mitrulinia ushuiae.^[6]

It produces a stipitate-capitate ascocarp (a fruiting body) arising from a substratal or sclerotial stroma tissue.^[7]
