Description:
Registration number: MB 513404
Description: Pileus 19–43 (55) mm broad, convex, dark gray (6D2–6E2) throughout initially, lighter gray (4C2–4C4) with age, finely rugulose, matted-fibrillose overwhite ground (under hand lens), overlain by a gelatinous pellicle throughout, glutinous, viscid in dry weather; margin lacking fibrils, entire, slightly inrolled when young; trama 0.5–1.5 mm thick at margin, 3–5 mm over tubes, 12–14 mm over stipe, white, solid, unchanging. Odor mildly fungoid; flavor mild. Tubes 2–4 mm long at margin, 6–8 mm centrally, 10–12 mm at stipe, narrowly and strongly depressed around stipe, of irregular lengths, concolorous with pores, slightly browning on exposure; pores white when young, maturing to light pink-gray (7B3–7C3), slightly browning with pressure, 1.5–3 per mm, isodiametric to subovate. Stipe 55–80 3 3–6 (13) mm, subequal, gradually and tapering slightly inward toward base, entirely white, browning slightly with handling, with fine erect scales imbedded in a dense gelatinous pellicle throughout; extreme base with fine white hyphal cords and occasional subtending concolorous ectomycorrhizas; trama white, solid, unchanging.
Distribution: Guyana
Ectomycorrhiza: Dicymbe corymbosa
