Hygrophorus angelesianus Sm. & Hes. 



Lloydia 5: 6. 1912 



Neohygrophorus angelesianus (Sm. & Hes.) Singer, Lilloa 22: I I 1 ). 

 1951. 



Pileus 2-2.5 cm broad, convex, the disc becoming slightly and shal- 



lowly depressed, "hair brown'' on the disc, "drab" on the margin ( dark 



sordid gray to grayish brown), not fading, glabrous, viscid, appearing 



as if varnished when dry, margin crenate-plicate. Context dark gray, 

 thin, firm; odor and taste not distinctive. 



Lamellae short-decurrent, "dark vinaceous drab" (purplish drab ). 

 distant, moderately broad, edges even. 



Stipe 4-5 cm long, 3-4.5 mm thick, concolorous with the pileus, 

 slightly enlarged above, apex fibrillose-furfuraceous, base whitish with 

 appressed fibrils, the remainder glabrous, stuffed. 



Spores 7-9 X 4-5.5 /*, ellipsoid, smooth, amyloid (pale blue to 

 dark blue in Melzer's reagent). Basidia 42-60 X 7-8 /x, 4-spored. Pleu- 

 rocystidia and cheilocystidia none. Gill trama of distinctly interwoven 

 (somewhat less so in dried material), vinaceous red to haematite red 

 in KOH, hyphae 4-12 /x broad. Cutis a narrow gelatinous zone. Clamp 

 connections present in the pileus trama and gill trama. 



Habit, Habitat, and Distribution — Singlv on soil, under heather, 

 Washington, June. 



Material Studied — Washington: Smith 14649 (type, from near 

 Heather Park, Mt. Angeles, Olympic Mts., June 28, 1939, at 6000 feet). 



Observations — This is a most peculiar species. It appears at first 

 sight to be a typical member of the section Camarophyllopsis because 

 of its waxy consistency, long flexuous basidia, and the distinctly inter- 

 woven gill trama. However, its amyloid spores and the \er\ distinctive 

 reaction of the flesh and gill trama in KOH are unique in Hygrophorus. 

 The fungus bears a striking resemblance to //. subviolaceus both in
