Summary: Section Subincarnatae (Smith), Section Polyadelphia (Maas Geesteranus); characterized by very small size, dull pale wine color, growth on sedges and rushes, and spores; Mycena juncicola (Fr.) Gillet is a different distinct species according to Maas Geesteranus which in his concept includes Mycena cariciophila Redhead found in New Brunswick; description derived from Maas Geesteranus(1) except where noted; Mycena culmigena found at least OR (type), WA, BC, (Redhead(8))
Cap: up to 0.3cm across, conic to convex, with or without small, acute umbo, "finally apically flattened to more or less depressed"; grayish vinaceous or with a purple tinge, paler to whitish at the margin; sulcate [grooved], not or little translucent-striate, minutely puberulous [downy] at first
Flesh: very thin, fragile
Gills: broadly adnate, decurrent with a tooth, ascending, 8-10 reaching stem, narrow (less than 0.05cm dry); pale grayish vinaceous, with grayish to whitish edge
Stem: 0.3-1cm x 0.01-0.02cm, equal, fragile, arising from an inconspicuous flat disc up to 0.1cm across; watery grayish white to grayish vinaceous, the disc vinaceous to brownish; pruinose in upper part, bald lower down
Odor: not distinctive
Taste: not distinctive
Microscopic spores: spores 9.4-12.1 x 4.6-5.4 microns, pip-shaped (broadly elliptic) to somewhat elongated, smooth, weakly amyloid; basidia 4-spored, 21.5-24 x 7.5-9 microns, clavate, clamped; pleurocystidia absent, cheilocystidia "forming a sterile band (lamellar edge homogeneous), 22-27 x 8-14.5 microns, obpyriform to clavate, regularly and symmetrically shaped, clamped (but clamps in later stages often difficult to demonstrate), fairly evenly covered with cylindrical, usually straight, simple or, less frequently, branched excrescences 1.8-8 x 0.9-1.5 microns"
Spore deposit: [presumably white]
Habitat / Range
on decaying sedge leaves and stems (Maas Geesteranus), on sedges and rushes, along lake, river, and ocean shores, (Redhead(6))
like Mycena juncicola of Europe which has been found in New Brunswick; Mycena pterigena has different habitat and no gelatinous pellicle; Mycena tubarioides has cap 0.2-0.7cm wide, fruits on decayed leaf sheaths of Juncus (rush) and Typha (cat-tail) and stems of Scirpus (club-rush) in wet places, does not arise from a disc
