ZELLER & DODGE—LEUCOGASTER AND LEUCOPHLEBS 895 
ox-blood red to garnet-brown on drying, surface uneven, shining; 
fibrils anastomosing, free in places, black, shining; peridium 60- 
80 u thick, duplex, outer layer readily separating from the inner, 
leaving patches 20-30 д thick, of large, septate, olive-brown 
hyphae; inner layer 40-50 џ thick, of slender, reddish brown, 
granular, closely woven hyphae; gleba milk-white when fresh, 
drying cinnamon or clay-color; cavities globose to polyhedral, 
filled; septa thin, 50-60 y, hyaline, of large, parallel, thin-walled, 
hyaline hyphae, scissile; basidia hyaline, 7 X 12 д, narrowly 
oblong, 2-spored; sterigmata 2-4 y long; spores light olivaceous 
under the microscope, globose, minutely verrucose with a gelatin- 
ous sheath, 7-9 шіп diameter. 
Under leaf mould in beech forests. Europe and North America. 
Summer. 
The duplex character of the peridium, the color both when 
fresh and upon drying, as well as the very thin peridium, should 
serve to distinguish this species from other members of the genus.
