Observation 223795: Mycena cinerella (P. Karst.) P. Karst.
When: 2015-11-21

Notes: Among layer of needles on a rotting redwood log. Odor raphanoid when crushed. Fragile, but lamellae relatively tough, do not break immediately when pulled with forceps.

Basidia 4-spored, ~28+5 x 8; there are some that appear 2-spored. Spores 7-7.5 × 4-4.5 on a small sample (5). Cheilocystidia forming sterile edge, pleurocystidia absent. Pileipellis of hyphae (~4 microns wide), embedded in gelatinous matter, but not diverticulate. Clamps everywhere.

Far from certain about the id. Yellow-tinted stems are not mentioned in descriptions of cinerella. “Tender gills” and “odor strongly farinaceous when cut” are further mismatches.
