Crepidotus variabilis - Variable Oysterling Crepidotus variabilis - the Variable Oysterling

Taxonomy

Phylum: Basidiomycota

Class: Agaricomycetes

Order: Agaricales

Family: Inocybaceae

Crepidotus variabilis is a tiny, kidney-shaped fungus that appears on dead twigs of broad-leaved trees in autumn and winter. The attachment is virtually always sessile (having no stem).

Many authorities give this genus family status as Crepidotaceae, while others include the genus Crepidotus within the family Inocybaceae; this should be a warning that these little fungi are not for eating, as some Inocybe species are deadly poisonous.
