This is the most common Galerina species in my area (central Illinois), where I find its tiny caps rising above moss beds from May to September. It features a stem that is adorned with tiny whitish flecks and fibrils, a prominently lined cap, and lacks a distinctive odor. Many species are more or less identical to the naked eye, however, so microscopic examination is required for certain identification. Galerina vittiformis features large, long-necked hymenial cystidia, finely verrucose spores, and a cap surface that lacks cystidia.
There are two forms of Galerina vittiformis--one with 2-spored basidia (featured here) and one with 4-spored basidia that produce slightly smaller spores, Galerina vittiformis f. tetraspora. Galerina atkinsoniana is a very similar species that features cystidia on the cap surface. According to Gulden (2010),
Galerina vittaeformis is an alternate spelling.
Ecology: Saprobic; growing alone, scattered, or gregariously in moss; summer and fall; probably widely distributed in North America. The illustrated and described collections are from Illinois.
Cap: 2-6 mm; conic at first, becoming broadly conic or convex; dry; bald; medium orangish brown to dull brownish; fading markedly as it dries out, creating a two-toned appearance; the margin lined, almost to the center.
Gills: Narrowly attached to the stem; nearly distant; short-gills present; colored like the cap.
Stem: 7-35 mm long; 0.5-1 mm thick; more or less equal; fragile; dry; when fresh adorned with tiny fibrils; whitish to yellowish above, brownish below; basal mycelium white.
Flesh: Insubstantial; unchanging when sliced.
Odor: Not distinctive.
Chemical Reactions: KOH negative to reddish on cap surface.
Spore Print: Cinnamon.
Microscopic Features: Spores 9-13 x 6-7 µ; subamygdaliform to widely subfusiform; verruculose; orangish brown in KOH; dextrinoid. Basidia 2-sterigmate. Pleurocystidia and cheilocystidia 40-75 x 5-15 µ; lageniform, with a long neck and a rounded, subacute, or subcapitate apex; smooth; thin-walled; hyaline in KOH. Pileipellis a cutis. Clamp connections present.
