8. Rhizopogon occidentalis Zeller & Dodge, sp. nov. 
Fructificationes piriformes vel irregulares, 1-4 cm. diametro 
metiens, citrinae recens lectae, odor massae male fermentatae (Неп- 
dersonis memoranda), “light buff" vel *mummy-brown" (Ridg- 
way) siccatae; funieuli superne innati-applicati, prominescentes et 
liberi inferne, tensi et peridium constringentes, “Hessian brown" 
(Ridgway) ; peridium tenue, 60-240 д crassitudine, simplex, bys- 
soideum, hyphis tenuibus contextum, sub lente cremeum vel "buck- 
thorn-brown" (Ridgway) ; gleba siccata, *pale yellow-orange" vel 
"Sudan brown" (Ridgway), тын Тосеш globosi aut irregulares, 
vacui; septa circa 20-60 р crassit tudine, hyphis hyalinis contexta, 
scissilia; basidia late баайа, 14x4 y, hyalina, sterigmatibus 
brevibus; sporae acrogenae, ellipsoideae, cremeae, 7-9Х3-5 y, leves. 
Habitat in terra arenoso in pinetis. America occidentalis. Veri. 
Type: in Coll. N. Y. State. 
Fructifications pyriform to irregular, 1-4 cm. in diameter 
when dry, color lemon-yellow when fresh (Henderson's field 
notes), drying light buff to mummy-brown; odor like sour 
dough or soured bread (Henderson); fibrils prominent, in- 
nate-appressed at the extreme summit, more prominent below 
and becoming free in the dried specimens, often stretched, 
constricting the peridium, color Hessian brown; peridium 
thin, 60-240 и, simplex, context cottony, made up of fine 
hyphae, cream-colored to buckthorn-brown under the micro- 
scope; gleba pale yellow-orange to Sudan brown when dry, 
brittle; cavities globose to irregular, empty; septa about 
20-60 u broad, made up of hyaline hyphae, scissile; basidia 
broadly clavate, 144 д, hyaline; sterigmata short; spores 
acrogenous, cream-colored, ellipsoidal, 7-9 3-5 д, smooth. 
In sand under conifers. Western United States. Early 
spring. 
This species differs from R. luteolus in larger size, lighter 
color, more prominent and darker-eolored fibrils, in much 
thinner peridium, softer context, more globose cavities, more 
cylindric basidia, shorter sterigmata, and lighter-colored, 
smaller spores.
