Omphalina wellingtonensis G. Stev. 1964
[GS] Pileus 1-2 cm. diam., orange darker at centre, plane becoming concave, margin slightly exceeding gills, matt; flesh thin, orange. Gills decurrent, orange-yellow, shallow, crowded. Stipe 2-3 cm. x 1-1.5 mm., orange, smooth, hollow, fragile. Spores 10 X 4.5um, non-amyloid, thin-walled; print white [EH] Examination of the type material and of additional fresh carpophores showed clearly that this rather common species in New Zealand does not belong in Omphalina. The specific characters indicate a distinct relationship to Gerronema sensu. Singer. More studies are necessary to extend our knowledge of this peculiar agaric. [JAC] type material shows the characteristic frosty and resinous edge to the gill seen in later material. Exuding oil drops into melzers. There can be no doubt this is the same as PDD 80829, PDD 87414, PDD 96314 and apparently PDD 105747 which is much paler. Sequences indicate it occupies an isolated position with Mycena acicula and other orphans from Mycena, much close to Atheniella in need of a new generic name, and probably family (atheniellaceae).
