little white crep

Crepidotus epibryus

Description:

This genus of small, brown-spored pleurotoid mushrooms contains a multitude of boring whitish to brownish species and a few (well, two) that are more interesting. The rare Crepidotus cinnabarinus is bright red, and Crepidotus crocophyllus usually features yellow to orange gills . . . but everything else is brown or white, and requires extensive microscopic study for accurate identification. ( http://www.mushroomexpert.com/crepidotus... ) ===== ---Pileus 3-10 mm broad, sessile, semiorbicular, ungulate, finally more or less applanate, white, villose or silky, margin even, incurved. Context whitish, thin; odor and taste mild. ----Lamellae radiating from a lateral point, white, then pale pinkish-brown, close or nearly subdistant, broad or moderately so, edges paler, fimbriate. ----Spores 7.5-10 (11) x 4.5-6 µ, ellipsoid to subovoid, base more or less pointed, slightly inequilateral in profile, surface wrinkled-verruculose. Basidia 28-35 x 6-8 µ, 4-spored. Pleurocystidia none; cheilocystidia 25 -58 (70) x 4-9 µ, filamentous, clavate, flask-shaped or ventricose with a slender neck. Gill trama subparallel to slightly interwoven, hyphae 3-7 µ broad. Pileus trama interwoven. Cuticle not always sharply differentiated, the surface bearing a turf of colorless hyphae, 3-7 µ broad, the apical portions at times crooked or coiled. Clamp connections present

Habitat:

Habit, Habitat, and Distribution: On hardwood, Colorado, Michigan, and Tennessee, June-August; also in Europe ( http://www.svims.ca/council/Crepid.htm )

Notes:

Observations: This species grows on hardwood and, in Europe at least, is often associated with mosses. The wrinkled-verruculose spores which are usually more or less pointed at the basal end, the long lecythiform cheilocystidia, and the crooked to coiled epicuticular hyphae are distinctive features of this species. We have followed Pilát's concept in our studies of C. epibryus. Whether his concept is the same as that of Fries is uncertain ( http://www.mykoweb.com/Crepidotus/specie... ), ( http://www.mycobank.org/MycoTaxo.aspx?Li... ), ( http://www.soortenbank.nl/soorten.php?so... ),
