Summary:
Section Polita. Tricholomatoid shape. Entoloma clavaformipes is distinguished by a yellowish brown, opaque cap 3-3.5cm across, a club-shaped stem 3-3.5cm long, isodiametric spores, and intracellular pigment, (Largent(1)). The description is derived from Largent(1).
Collections were examined from BC and FL (Largent(1)).
Cap:
3-3.5cm across, flat and broadly depressed, margin decurved [downcurved], entire then eroded, eventually somewhat wavy; hygrophanous, yellowish brown fading to grayish orange or orange-white; opaque
Flesh:
up to 0.5-0.6cm thick near gill attachment, fragile; white
Gills:
adnate to uncinate, subdistant, narrow, 0.3-0.4cm broad, somewhat ventricose [broader in middle]; white, presumably becoming pinkish, edges colored as faces; edges even
Stem:
3-3.5cm x 0.4-0.5cm at top, equal or slightly widening downward, (also described as clavate), terete [round in cross-section] to more often flattened and grooved; at first white becoming brownish orange from base upward; at first covered with "dense or abundant, fine, white tomentum", [presumably non-viscid]
Veil:
absent
Microscopic spores:
spores 7.2-10.1 x 5.8-8.4 microns, 5-6 sided, distinctly angular, isodiametric [as wide as long], [smooth, inamyloid]; basidia in type 4-spored, 27.6-46.24 x 10.56-13.20 microns; pleurocystidia absent, cheilocystidia absent; cap cuticle a cutis, pileocystidia cylindric; stem cuticle a cutis without caulocystidia; clamp connections present on all parts; cytoplasmic pigmentation, hyphae not incrusted at all
Spore deposit:
pinkish brown
