"Gyroflexus brevibasidiatus", the type, amongst the vaguely omphalinoid genera is distinguished by its small, mammiform pileus, growth on "Sphagnum", and lack of cystidia [cite journal | author=Redhead, S.A. |year=1985| title=Omphalina brevibasidiata| journal=Fungi Canadenses| volume=294 [http://www.cbs.knaw.nl/mycoheritage/fungi-can/fungi-can_pdf/294.pdf] ] .

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.
