Spores 5-7 X 3.5-4.5 ~, broadly ellipsoid to subglobose, smooth,
hyaline in Melzer’s solution. Basidia 40-50 X 5-6 ~, 4-spored. Pleurocystidia
not seen. Gill trama of interwoven narrow hyphae, 1.~3 ~
broad. Cuticle a trichodermium, hyphae 2-5 ~ broad, more or less erect

HABIT, HABITAT, AND DISTRIBUTION-On the ground in woods and
in a dried-up pool, Massachusetts, Michigan, Idaho, and Washington,
July-November. MATERIAL STUDIED-IDAHO: Smith 54279, 582.39. MASSACHUSETTS:
Bigelow 9130. MICHIGAN: Imshaug 4812; Smith 33115, 33151, 33159,
33163,41726,50254. WASHINGTON: Kauffman, Lake Quinault, Oct. 16,
1925; Murrill 568 (type, from Seattle, Oct. 20 to Nov. 1, 1911).
OBSERVATIONs-Notes on the type: Spores 5.5-7 (8) X 3.5-4.5 tt,
ellipsOid, smooth, pale yellow in Melzer’s reagent. Basidia 34-46 X
4-6 tt, 4-spored. Pleurocystidia and cheilocystidia none. Gill trama
interwoven. Cuticle of loosely tangled non-gelatinous hyphae. Clamp
connections present on the cuticular hyphae. The species is very close
to H. pratensis but differs in color. http://www.mykoweb.com/...
