Species Information

Summary:

Not available
Fruiting body:
0.3-0.6cm wide at tip, 0.1-0.2cm wide at base, 0.5-3cm high, clavate [club-shaped] when young, becoming obconic or trumpet-shaped with wide, cup-like apex; white when fresh, becoming ''yellowish white'' on drying and finally strong ''orange yellow'' ("ochraceous-orange"); smooth, (Dodd), 0.8-3cm high, mostly 1.4-1.8cm high, stemmed with an elongate obconic truncate head, 0.4-0.9cm wide at the sterile, flat, or slightly concave top; white becoming ochraceous when old and even orange upward, paler in lower part; "margin of the head thin, upturned or expanded, even deflexed and almost involute at times, wavy or lobed, or with incipient pyxidate branching"; hymenium covering the sides of the head, smooth or becoming vaguely longitudinally rugulose [wrinkled] especially when dry, (Corner), translucent (Doty)
Flesh:
white (Dodd), waxy, very soft, hygrophanous, (Corner)
Stem:
basal mat effuse [spread out flat], strigose, white, (Dodd), stem 0.05-0.1cm wide, solid, cylindric, slightly dilating into the head; white pruinose, with scattered white hairs at the base, (Corner)
Taste:
unknown (Dodd)
Microscopic:
spores 3.0-4.0(4.5) x (2.0)2.5-3.0(3.2) microns, nearly round, smooth or slightly asperulous [rough] (this only faintly discernible at high magnification (x3,200)), weakly amyloid (light blue green), white, thin-walled; basidia (2-)4-spored, 16-30 x 3.5-4.5 microns, narrowly clavate, almost cylindric, clamped; gloeocystidia 4.5 microns wide, usually not projecting but occasionally projecting up to 10 microns, with yellowish refractive contents or empty, cylindric, leptocystidia absent; hymenium plus subhymenium 30-50(60) microns thick, decurrent to about 0.5cm from base, not gelatinous; subhymenial generative hyphae 1.5-2.5 microns wide, short-celled, very tightly interwoven, without clamp connections, gloeoplerous hyphae as in context but occasional; context tissue slightly aerenchymatous in older fruitbodies only, generative hyphae up to 12 microns wide, inflated, colorless, thin-walled, without clamp connections, gloeoplerous hyphae "2.0-6.0 microns wide, rare, present only near subhymenium, often culminating in hymenium as gloeocystidia", (Dodd)
Spore Deposit:
white (Buczacki)

Habitat / Range

gregarious, usually single, occasionally paired, on leaf duff usually under conifers, often Taxus (yew), "appears to lack the lignicolous habit, but the fruit bodies are attached to twigs and needles in the duff on the ground", also on hardwood leaves though under Taxus, or on bare ground, (Dodd), single or 2-3 together, or subcespitose, on moist, very rotten leaves and twigs of hardwood trees and conifers under prostrate branches of Taxus brevifolia (Pacific Yew) and Pseudotsuga menziesii (Douglas-fir), (Corner), mostly growing erect from small bits of charred wood, needles, and small twigs and among mosses under heavy cover of small Douglas-firs in dense coniferous woods, October, (Doty), fall to winter (Buczacki)
