NEW SPECIES OF FUNGI. 19 



Acremoiiium flexuosum. 



Plate 1, figs. 16-18. 



Flocci procumbent, interwoven, branched, forming a thin, soft, 

 tomentose, white or cream-colored stratum, the branches widely 

 divergent, sometimes opposite, narrowed and rlexuous toward the 

 tips and bearing scattered, alternate spicules or sporophores ; spores 

 oval or elliptical, .0005 to .0008 in. long, .0003 to 0005 in. broad. 



Decaying wood. Griffins, Delaware county. September. 



From Acremonium album it differs in habit and habitat, as well as 

 in the flexuous terminal portions of the fiocci and their alternate 

 pointed spicules ; and from Acremonium alternatum it is distinguished 

 by its elliptical spores. 



Sepecloiiiuin brunneum. 



Effused, pulverulent, brown ; spores globose, rough, .0008 to .001 

 in. in diameter. 



Decaying fungi. Gansevoort. August. 



This is similar in habit to Sepedonium chrysospermum, from which 

 its dark snuff-brown spores distinguish it. Like that fungus, this 

 is also probably a mere state of some species of Hypomyces. 



Morcliella angusticeps. 



Plate 1, fig-s 19-21. 



Pileus narrowly conical or oblong-conical, acute or subobtuse, 1 to 

 2 in. long, its diameter at the base scarcely exceeding that of the 

 stem, pale-buff or cream-colored, adnate, sometimes a little curved, 

 the costae longitudinal, anastomosing or connected by transverse 

 veins ; stem snbequal, hollow, furfuraceous, even or sometimes 

 marked by irregular longitudinal ridges and furrows, whitish, about 

 equal to the pileus in length ; asci cylindrical ; spores elliptical, 

 yellowish, .0008 to .001 in. long, .0005 to .0007 broad. 



Borders of woods and open places. Albany and Karner. April 

 and May. Edible. 



This morel is perhaps too closely related to Morcliella conica Pers., 

 but if that species is correctly represented in Mycographia, plate 81, 

 fig. 315, our plant is easily distinguished by its much more narrow 

 pileus, which scarcely exceeds the stem in diameter. The para- 

 physes of that species are also represented as filiform, and are de- 

 scribed (1. c. p. 182; as thickened above. In our plant I find no 

 such paraphyses, but instead of them there are oblong or subclavate
