Cap: 0.5-3.6 cm broad. Conic to convex, eventually
subcampanulate, expanding to broadly convex, and typically acutely
umbonate with a sharp papilla. Surface smooth to translucent-striate
near the margin, viscid when moist from a thick, separable gelatinous
pellicle. Colour pale reddish brown to honey to ochraceous,
hygrophanous, fading in drying to yellowish olive to ochraceous or
yellowish buff. Flesh whitish to honey coloured, bruising bluish where
Gills: Attachment adnate,
sometimes sinuate or uncinate, whitish clay at first, eventually dark
purplish brown at maturity, with whitish edges.
Stem: 20-90 mm long by 0.5-4
mm thick. Equal to slightly swollen at the base. Colour whitish at
first, soon reddish brown or honey coloured, and sometimes with grayish
bluish green tones. Surface covered with whitish fibrillose patches to
a fairly persistent, superior densely fibrillose to membranous annulus
that develops from a thickly cortinate partial veil.
Microscopic features: Spores
dark purplish brown in deposit, subellipsoid or ellipsoid, 9.5-16 by
6.5-9.5 microns. Basidia 4-spored. Pleurocystidia absent.
Cheilocystidia 20-32 by 4-8 microns, venttricose-fusiform or lageniform
with a narrow neck, often flexuous, 4-15 by 0.5-1.5 microns,
Habit, habitat and distribution:
Grows solitary to gregariously on horse manure, in grassy areas or in
rich soils, and often fruits in large rings. Known from Canada (British
Columbia and New Brunswick), the Pacific Northwest (Washington, Oregon,
and Idaho), Chile, Great Britain, and Europe. Probably more widely
distributed than presently reported. Generally found in October and
November, but in Chile, this mushroom has been collected in August.
It's fruiting range is probably much greater than presently reported.
