ZELLER & DODGE—LEUCOGASTER AND LEUCOPHLEBS 897 
basidia, 20 x 5 u; no paraphyses; sterigmata short; spores hy- 
aline, reticulate in gelatinous sheath, globose to slightly ellipsoidal, 
8-11 шіп diameter. 
California. June to July. 
'The freshly cut gleba exudes а milky juice, probably a dense 
suspension of spores, as no definite latex organs were seen. This, 
with the large, spherical empty cavities and its color, makes it 
quite easy to recognize in the field. 
Specimens examined: 
California: Shasta County, Castle Crag, H. W. Harkness, 251, 
type (in Dudley Herb. at Leland Stanford Jr. Univ.) ; Santa Clara 
County, Saratoga, Boys’ Outing Farm, Н. E. Parks & C.W. Dodge 
(in Dodge Herb. 1529).

1: 258. 1899; Saccardo & Sydow in Sace. Syll. Fung. 16: 252. 
1902. 
Type: in Dudley Herb. at Leland Stanford Jr. Univ. 
Fructifications subglobose, 1 em. in diameter, white or faintly 
citron color; fibrils few, small, white; columella wanting; peridium 
thin, 75-100 u thick, of very slender, compactly woven hyphae, 
homogeneous with the septa which show through as reticulations 
or pits on the surface; gleba white, cavities rounded, filled with 
hyphae; septa 75-100 p. thick, of 3 layers, the middle layer of 
compactly woven, gelatinized hyphae, subhymenial layer of 
larger, more loosely woven hyphae; basidia clavate, 12 X 7), 
disappearing, leaving spores sticking to walls of the cavity 
hyphae; sterigmata long; spores hyaline, guttulate, reticulate in а 
gelatinous sheath, sometimes slipping out at maturity, globose to 
slightly ellipsoidal, 7-12 и. 
Moist earth. British Columbia to California. July to Sep- 
tember. 
Leucophlebs gibbosum Harkness, herb. nom., is а lighter form, 
irregular in shape but structurally similar (Harkness 124, without 
locality data in Dudley Herb. at Leland Stanford Jr. Univ.).
