Notes on some Corticioid lignicolous fungi associated with snowbanks in southern Arizona

Seven species of corticioid Hymenomycetes that fruit on wood in snow or near the edges of snowbanks in southern Arizona are discussed. Basidiocarps of Coniophora corrugis and Corticium lepidum apparently develop only in snow. Athelia decipiens, A. epiphylla, Leptosporomyces galzinii, Confertobasidium olivaceo-album, and Byssomerulius hirtellus produce actively sporulating basidiocarps in snow, but also fruit readily during the late summer and fall rainy season.
