SUBSECTION HYGROPIIORUS 289 



floccose. Context grayish white; odor and taste none. 



Lamellae adnate to decurrent, white with a pale pinkish-butt re- 

 flection, rather thick, close, broad. 



Stipe 3-6 cm long, 8-15 mm thick (broader when compressed), 

 white, with a layer of white-floccose fibrils beneath the glutinous veil, 

 peronate-slimy up to a superior line, when dry white floccose at the 

 apex, often enlarged downward, solid. 



Spores 9-13 X 5.5-7 /x, ellipsoid, smooth, pale yellow in Melzer's 

 reagent. Basidia 52-77 X 7-9 /x, 4-spored. Pleurocystidia and cheilocys- 

 tidia none. Gill trama divergent, hyphae 6-12 fx broad. Cuticle a gelati- 

 nous zone 90-250 /x thick, hyphae tangled, pale fuscous, narrow (3-4 /x) 

 broad. No hypodermium differentiated. Pileus trama interwoven, hy- 

 phae radially disposed. Clamp connections present on the cuticular 

 hyphae. 



Habit, Habitat, and Distribution — On soil, New York, Michigan, 

 Colorado, Idaho, Washington, Oregon, and Canada; Europe, August- 

 November. 



Material Studied — Colorado: Kauffman, Tolland, Aug. 20, 1920. 

 idaho: Smith 47140. Michigan: Kauffman, Ann Arbor, Oct. 23, 1926; 

 Smith 1124, 15475. new york: Kauffman, North Elba, Sept. 1914; 

 Ithaca, Sept. 1903. Oregon: Kauffman & Brown, Takilma, Nov. 29, 

 1925. Washington: Flett 181. Canada: Cain, Ontario, Oct. 2, 1951. Aus- 

 tria: Moser 1948 (Hesler 24132). Belgium: Heinemann 1918. 



Observations — In Europe, apparently, the pileus is olive-gray to 

 blackish, Moser (1955). Peck's collection from North Elba, N. Y., 

 which he identified as H. fuscoalbus, has spores 7.5-9 /x long; it should 

 be called H. piistulatus. Bataille ( 1910, p. 189) lists anguinaceus Jungh. 

 as a synonym.
