ZELLER AND DODGE—GAUTIERIA 139 
granularly guttulate, septate, 4-5 и broad, some knobbed at 
the tip, some filiform; basidia hyaline, granularly guttulate, 
clavate, 20-26 9-10 u, 1-4-spored; sterigmata less than half 
the length of the spores; spores 11-16 6.5-8 и, short-pedicel- 
late, longitudinally striate, with 7-10 wavy striations, from 
English red to burnt sienna; young spores ovate to ellipsoidal, 
short-pedicellate, smooth, then striate. 
Under conifers. Idaho. September to October. 
The color of the gleba and the prominence of the columella 
make this species distinct from all others. It is most closely 
allied with G. Trabuti in tramal characters, but the spores 
are more nearly the size of G. monticola than those of any 
other species. 
Specimens examined : 
Idaho: Priest River, J. R. Weir, type (in Weir Herb., in 
Zeller Herb., 1458, and Dodge Herb., 859).

Type: in Dudley Herb. at Leland Stanford Jr. Univ. and 
in N. Y. Bot. Gard. Herb. 
Fructifications irregularly lobed, nearly plane above and 
below, 10 em. in diameter (Harkness), about 3 em. thick, Dres- 
den brown to mummy-brown; stipe short, slender, darker; 
columella short, branching, concolorous with the stipe; pe- 
ridium evanescent; gleba ochraceous-tawny, grayish where 
cut, due to the thick, hyaline septa; cavities irregular, more 
or less anastomosing, nearly filled with spores when dry; 
septa 140—400 и thick, hyaline, composed of more or less ge- 
latinized hyphae, mostly parallel with the hymenial surface; 
eystidia none; База arising from erect, septate hyphae, 
hyaline, 166-7 и, ovate, mostly 2-spored; sterigmata fili- 
form, 7-10 д long; spores acrogenous, l-several-guttulate,

sometimes slightly warted.
