Gerronema is a genus of small- to medium-sized lignicolous agarics with white, nonamyloid, basidiospores and decurrent lamellae.[1][2][3] The genus, first described by American mycologist Rolf Singer in 1951,[4] contains 13 species.[5]

Description

Typically the cap of the fruit bodies have a shallow to deep central depression, giving the umbrella-like to funnel-shaped caps the appearance of a belly button, or a belly with a navel. Similarly shaped agarics are said to be omphalinoid in appearance in reference to a morphologically similar genus, Omphalina. Gerronema differ from Omphalina by the absence of incrusting or intraparietal pigments typical of Omphalina, the occasional occurrence of bright colors, such as yellow or green absent in Omphalina, by the restriction to decay of wood, and by the tough tissues composed of sarcodimitic hyphae.
