Diagnostic characters
Small agaric, growing on the ground or bryophytes, with a rusty to ochre-brown spore print. Pileus brown, not viscid, translucent-striate or not. Lamellae adnate. Stipe central. Partial veil remnants absent. Spores pale, warty; plage absent; germ pore absent. Cheilocystidia present. Lamellar trama regular. Pileipellis a cutis. Clamp connections present.
Similar genera
Macroscopically these two species of section Mycenopsis are indistinguishable from other mycenoid species of Galerina, but the plage is lacking or very indistinct. The absence of veil remnants distinguishes them from most species of Cortinarius and Tubaria, and the growth on the ground (sometimes among moss) rather than wood or litter separates them from Gymnopilus. The capitate cheilocystidia of Galerina bunyaensis are similar to those in Conocybe, but in that genus the pileipellis is a hymeniderm. Cheilocystidia are also well developed in G. inflata, but are globose to elliptical.
Australian species
Two species: Galerina bunyaensis and G. inflata. These are keyed out separately because it is very unusual for species of Galerina to have warty spores that lack a plage. They both belong to Galerina section Mycenopsis, in which all other species have a plage.
Australian distribution
S.A., Qld and N.S.W. (and probably also Vic. and Tas.).
Habitat
In native forests.
Substrate
On the ground or among bryophytes.
Trophic status
Saprotrophic.
