Fungus Flora of Mt. Hood 123 



of times in Virginia and Maryland. The collections from that 

 region have spores which tend to average below 9 /x long, while in 

 the European plant the spores are given 10-12 x 7-8 yu by Ricken 

 (20) and 11-13 X 7-9 ^ by Boudier (5). In the West, a very 

 similar species is found, with the spores measuring 10-12 x 7-8 ix. 

 The latter I believe to be the genuine A. junquillea as described 

 in Europe. I do not feel sure that the plant from the Eastern 

 United States can properly be referred here, although it is cer- 

 tainly close to A. junquillea in most of its characters. One can 

 of course find occasional longer spores in the Eastern plant, but 

 to record such merely confuses the record. In this connection, 

 I should like to reiterate (12, p. 617) that A. russuloides Pk. is 

 a different and distinct species, and should not be included in 

 any synonymy under A. junquillea or A. gemmata. Some of 

 my collections in the East are very probably genuine A. gemmata

Amanita silvicola sp. nov. (See Plate IV.) — Pileus 6-10(12) 

 cm. broad, at first broadly convex, then plane to subrepand, 

 white, subviscid, when young covered by a soft, fioccose, contin- 

 uous white universal veil which later is irregularly disposed in 

 flat patches or masses, not warty, margin persistently incurved, 

 even, and at maturitj^ crenate from the appendiculate veil-rem- 

 nants; flesh abruptly thin on margin, scarcely over a centimeter 

 thick near stem, soft. Gills reaching stem, free except by de- 

 current lines, or obscurely and very narrowly adnate, white, crowded, 

 medium broad, 6-7 mm., edge distinctly flocculose. Stem 6-10 

 cm. long, at first with the pileus seated on a subnapiform bulb 

 and surrounded by the smooth, fioccose universal veil, at length 

 elongated and subequal, 15-25 mm. thick, bulb up to 3 cm. thick, 

 white, surface at maturity covered by obscure floccose-silky re- 

 mains of the veil, at times terminating in a narrow, quickly 

 evanescent fioccose annulus, bulb edged by a circular indistinct 

 line which is the edge of the separated veil, solid, rather com- 

 pact and firm. Odor and taste none. Spores 9-10(12) x 5- 

 5.5(6) At, elHptical, smooth, white, obliquely apiculate; basidia
