138 Forty-second Annual Report on the 



and in its closer lamellae. Its odor is obsolete but it lias a farinaceous 

 flavor. It is probably esculent, but has not been found in sufficient 

 quantity to afford a test of qualities. 



Clitopilus unitinctus, Ph. 



One-colored Clitopilus. 



Pileus thin, submembranous, flexible, convex or nearly plane, 

 centrally depressed or umbilicate, glabrous, subshining, often con- 

 centrically rivulous, grayish or grayish-brown, flesh whitish or 

 grayish-white, odor obsolete, taste mild ; lamellae narrow, moderately 

 close, adnate or slightly decurrent, colored like the pileus; stem slender, 

 straight or flexuous, subtenacious, equal, slightly pruinose, grayish- 

 brown, with a close white mycelioid tomentum at the base and white 

 root-like fibres of mycelium penetrating the soil ; spores elliptical, 

 .0003 in. long, .0002 broad. 



Var. alhidus. Whitish or grayish-white, not rivulose ; lamellae 

 broader; spores brownish flesh-color. 



Pileus 6 to 16 lines broad ; stem about 1 in. long, 1 line thick. 



Woods of pine or balsam. Albany and Essex counties. Autumn. 



The variety is a little paler than the typical form, with lamellae a 

 little broader, but is probably not specifically distinct. The species 

 is apparently closely related to G cicatrisatus but differs in color. 

 The pileus is somewhat silky-shining and is often wavy on the margin. 



b. Spores angular or irregular. 



1. Pileus not hygrophanous. 

 Clitopilus abortivus, B. & G. 

 Abortive Clitopilus. 

 Pileus fleshy, firm, convex or nearly plane, regular or irregular, dry, 

 clothed with a minute silky tomentum, becoming smooth with age, gray 

 or grayish-brown, flesh white, taste and odor subfarinaceous; lamellae 

 thin, close, slightly or deeply decurrent, at first whitish or pale-gray, 

 then flesh-colored; stem nearly equal, solid, minutely flocculose, some- 

 times fibrous-striated, colored like or paler than the pileus; spores 

 irregular, .0003 to .0004 in. long, .00025 broad. 



Pileus 2 to 4 in. broad; stem 1.5 to 3 in. long, 3 to 6 lines thick. 

 Ground and old prostrate trunks of trees in woods and open places. 

 Rensselaer, Lewis and Albany counties. August and September. 



This species is, in our State, the most abundant one of the genus. 

 It is commonly gregarious, but it is also scattered and caespitose. 

 Frequently it fails to develop properly, and then forms irregular or 

 subglobose fleshy whitish masses similar to those sometimes formed
