Fungus Flora of Mt. Hood 119 



than in our specimens and as given by Peck, I include here a 

 more complete description: Fruit Body 4-8 cm. tall, dichotom- 

 ously branched, with few to several main branches. Fertile 

 Branches occupying mostly only the upper half of the plant, 

 subfleshy, smooth, " avellaneous " (R.), or paler towards the tips, 

 dilated and compressed-subrugose upwards, terminal branches 

 attenuated-acute, with pointed apices in two's or three's. Stem 

 and sterile branches 3-4 cm. long, 3-8 mm. thick, rather tough, 

 clothed by a strigose-hairy thick covering, "army-brown" (R.) 

 to "avellaneous," subterete or compressed upwards; context 

 solid, subspongy, similar to, but of a deeper color than, the hy- 

 menium. Spores spherical, with abrupt slender apiculus, hya- 

 line, smooth, granular within, 9-10 {jl (11.5 with apiculus); ba- 

 sidia 1-2-spored, rarely 3-spored, on long subcurved sterigmata; 

 cystidia none. Odor none; taste mild or slowly somewhat 

 bitter. 



Growing on mossy humus or very rotten debris under coni- 

 fers. October. 



Pistillaria fusiformis, sp. nov. (See Plate II, Fig. 2.) — 

 Fruit Body fleshy, white, subfusiform-acuminate, 3-5 mm. tall, 

 somewhat curved, fertile portion subcompressed, sometimes fur- 

 rowed on the flattened side. Stem slender, scarcely more than 1 

 mm. long, terete, minutely hairy, white; sclerotium none. 

 Spores oval-elliptical to subglobose, 7.5 x 6 yU, hyaline, smooth; 

 basidia 45 x 8-9 jjl, 2- to 3-spored with prominent, slender sterig- 

 mata; cystidia none. 



On decayed coniferous wood. Gregarious. Mt. Hood, Ore- 

 gon. October 7. Collected by L. E. Wehmeyer. 



The body is entirely fleshy, spongy and homogeneous within. 

 The general shape and appearance are like that shown by Pa- 

 touillard (18) for P. rosellae var. ramosa, Fig. 53, but otherwise 

 different. 



Typhula phacorrhiza Fr.  — In alder thickets. 



Typhula cystidiophora, sp. nov. — Fruit Body simple; fer- 

 tile portion cylindrical, 2-5 cm. long, 1-1.5 mm. thick, obtuse, 

 subpruinose or almost glabrous under a lens, white or tinted pale 

 yellowish; context soft, fleshy, subfragile. Stem filiform, 2-2.5
