Sphagnurus is a parasitic mushroom genus in the family Lyophyllaceae[1][2] that creates conspicuous dead patches on peat moss (Sphagnum) in bogs.[3][4][5] The genus contains one species known to inhabit Eurasia and North America.[1][6] Phylogenetically the genus is closest to, but is isolated from species now classified in the genus Sagaranella[1][2][7][8] Prior to molecular analyses, the most recent classification put it in the genus Tephrocybe, but that genus is allied to Termitomyces.[1][2]

Sphagnurus paluster, the single species in the genus is pale grey and has a mycenoid stature (i.e. has a conical pileus, a narrow elongated stipe and lacks an annulus or volva). Its basidiospores are nonamyloid and smooth. It lacks cheilocystidia and pleurocystidia. Clamp connections are present.[1]

Etymology

[edit | edit source]

The name Sphagnurus is supposed to be derived from the name of its host Sphagnum and Latin -urus, meaning “tail".[1] The ancient Greek word οὐρά however means “tail".[9]
