396 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Fructifications subglobose to irregular, at first whitish to flesh- 
pink, becoming brick-red to Hessian brown, surface smooth, 
uneven, viscid when moist; fibrils concolorous or darker, innate- 
appressed; peridium usually 15-35 y thick (sometimes 40-60 u), 
composed of gelatinized pseudoparenchyma, drying brittle and 
orange rufous, lined with the fine, hyaline hyphae of the outer 
layer of the gleba (showing white in cross-section); gleba drying 
cream-color or ivory-yellow when cut after drying; cavities aver- 
aging about 2 to the mm., globose to polyhedral, lined with a 
clear gelatinous mucus, embedding the long-pedicelled basidia and 
spores; septa hyaline, 35-55 y. thick, of thin-walled hyphae, be- 
coming scissile; basidia not in a definite hymenium, hyaline, pyri- 
form, 15-25 x 8-14 y, on pedicels 50-125 y long, 4-spored; sterig- 
mata 2-4 y long; spores spherical to oblong, echino-reticulate, 
almost hyaline, 11-15 y (including gelatinous sheath), spore alone 
6-10 y. 
In leaf mould under maples. Oregon. May. 
The thin pseudoparenchymatous peridium, which is vivid red, 
and the echino-reticulate spores separate this species from others 
of the genus.
