Nivatogastrium fungi kingdom
Nivatogastrium is a genus of secotioid fungi in the family Strophariaceae. The genus has contained four species found in North America and New Zealand, but the type species is now considered to be a gasteroid species of Pholiota, and was transferred to that genus in 2014.

Taxonomy
The genus was circumscribed by American mycologists Rolf Singer and Alexander H. Smith in 1959, who set N. nubigenum (then known as Secotium nubigenum Harkness) as the type and only species. In 1971, Egon Horak described the species N. baylisianum, N. lignicola, and N. sulcatum from New Zealand.
The generic name is derived from two words, nivatus and gastrion; nivatus refers to the type locality, Sierra Nevada, and to the fact that the mature fruit bodies fade in color to white.
