Hygrophorus proximus Krieger 



Mvcologia 19: 310. 1927 



Illustration : 



Krieger, Mvcologia 19, pi. 34, fig. 3. 



Pileus 5.5 cm broad, slightly repand, pinkish-creamy, and with a 

 fine purplish-red scattered tomentum that forms darker spots of purple- 

 red on the moderately elevated disc. Context very thin toward the 

 margin, white or very faintly pinkish. While drying, the plant emitted 

 an odor of rancid lard. 



Lamellae markedly decurrent, creamy white, very narrow, 

 crowded, unequal. 



Stipe 5 cm long, 12 mm thick, white, with a pinkish-lavender tinge, 

 tapering a little below, slightly fibrillose with a few purplish fibrils, 

 punctate above with pale tomentose dots. 



Spores 5.5-7.5 X 3.5-4.5 /x, ellipsoid, smooth, pale yellow in Mel- 

 zer's reagent. Basidia 36-42 X 5-7 jx. Pleurocystidia and cheilocystidia 

 none. Gill trama of divergent hyphae. Cuticle an ixocutis, 60-200 /x 

 thick, hyphae loosely interwoven. No hypodermium differentiated. 

 Clamp connections few. 



Habit, Habitat, and Distbibution — On soil, Maryland, October. 



Matebial Studied — mabyland: Kelly 287 (type, collected by 

 Olga Kelly, Belair, Oct. 7, 1919). 



Obsebvations — A portion of the type is deposited in the University 

 of Michigan Herbarium. The dried gills of it are very difficult to sec- 

 tion. 



Krieger ( 1927 ) reports the following observations : "It seems near 

 H. erubescens Fries, hence the specific name. The gills of my plant are 

 much closer and narrower, and the spores considerably smaller than in 

 the Friesian species." 



The above account of microscopic characters is based on our study 

 of the type. The macroscopic characters given above are from Krieger 

 (1927). 



A note accompanying the specimen states that half of a carpophore 

 is deposited in the National Herbarium.
