Gymnopus cf. striatipes (Peck) Halling

Densely fasciculate (9) on decayed hardwood log in beech-maple forest, Spednic Lake Protected Natural Area, New Brunswick (17-06-18/03).

Basidiospores white in spore print, ellipsoidal to dacryoid, smooth inamyloid, 3.7-4.7 X 2.5-2.9 μm, D/d = 1.45-1.71 (average[30]: 4.2 X 2.7 μm, D/d = 1.57). Cheilocystidia scattered, inconspicuous, clavate to branched or lobed. Pileipellis a thin cutis of narrow repent hyphae, without branched or lobed elements.

Gymnopus cf. ocior, as presented on our pages, is very similar and could be the same. Its basidiospores are also very small and are similar, although slightly narrower, to those of Collection 17-06-18/03. It is also similar to Gymnopus dryophilus but differing in its densely fasciculate growth, pileipellis composed of a simple cutis and its very small basidiospores. The average length of the basidiospores is below that given as an extreme low measurement (4.8 μ) by Halling on his website. Both G. confluens and G. acervatus have densely fasciculate growth but both of these have larger basidiospores and differ on other features as well.
