218 Peck: New species of fungi 



fragile, minutely flocculose, appendiculate with minute fragments 

 of the whitish veil, sometimes striate on the margin, grayish- 

 brown, whitish or grayish on the margin ; lamellae ascending, 

 thin, brittle, moderately close, adnate, pale olive-green becoming 

 darker and finally black ; stem very long, slender, fibrous, rather 

 tough, hollow, straight or nearly so, ashy-gray above, chestnut- 

 colored below, sometimes slightly thicker toward the base ; spores 

 broadly elliptic, black, abruptly narrowed at the ends, 15-20/z 

 long, 10— 12 fx broad. 



Pileus 1-2 cm. broad ; stem 5-9 cm. long, about 1 mm. thick. 



Gregarious. Grassy ground. Falmouth, Massachusetts. June. 

 S. Davis. 



This species is ambiguous, combining the characters of Panae- 

 olus and Psathyrella. Its spores are similar in size and shape to 

 those of some species of Panaeolus, but the tendency of the pileus 

 to become striate on the margin, which is apparently straight and 

 does not extend beyond the lamellae, and the uniform color of the 

 latter, indicate that its proper place is in Psathyrella. 



Hydnum Blackfordae 



Pileus fleshy, convex, glabrous, grayish or greenish-gray, flesh 

 whitish with reddish stains, slowly becoming darker on exposure ; 

 aculei subulate, 2-5 mm. long, yellowish-gray becoming brown 

 with age or in drying ; stem equal or slightly tapering downward, 

 solid or stuffed, becoming hollow in drying, glabrous, colored like 

 the pileus ; spores brown, subglobose, verrucose, 8-10// broad. 



Pileus 2.5-6 cm. broad ; stem 2.5-4 cm. long, 3-4 mm. thick. 



Mossy ground in low springy places in damp mixed woods. 

 Ellis, Massachusetts. August, 1904. Mrs. E. B. Blackford. 



This species is peculiar in its colors and in its rather long stem. 

 Sometimes there is a slight pinkish tint visible on the pileus. In 

 the dried specimens blackish hues have been assumed, especially by 

 the stems. The species is dedicated to its discoverer. It is ap- 

 parently very rare. 



Craterellus Pogonati 



Pileus membranaceous, sessile or stipitate, irregular, 2-4 mm. 

 broad, minutely tomentulose, white ; hymenium even, pale creamy- 

 yellow ; stem when present lateral or eccentric, slender, tomentu- 

 lose or sometimes glabrous on one side by reason of the decurrent 

 hymenium, white.
