Gyroflexus

A monotypic genus with a yellowish-ivory colored omphalinoid agaric in the Hymenochaetales that grows on living Sphagnum^[1][2][3] Phylogenetically related agarics are in the genera Rickenella, Blasiphalia, Loreleia, Cantharellopsis and Contumyces, as well as the stipitate-stereoid genera Cyphellostereum and Cotylidia and clavaroid genus, Alloclavaria^[4]. Gyroflexus brevibasidiatus, the type, amongst the vaguely omphalinoid genera is distinguished by its small, mammiform pileus, growth on Sphagnum, and lack of cystidia^[5].

Etymology

The etymology of the name Gyroflexus is not known. When coined in a prepublication advertisement, it clearly was intended to be applied to several species, although only one, the type was included. Possibly it refers to the slightly undulating stipe in contrast to the very straight stipes of related genera like Rickenella for which the same author coined that name years earlier. The name Sphagnomphalia is synonymous.
