and the elongated clavate columella. The young plant is 
ovate-acuminate before the rupture of the exoperidium ; the 
latter when spreading measures 2-3 inches across. 
Geaster striatus, D. C. (Fig. 28). Exoperidium split into 
6-9 subequal coriaceous, thin, acute segments ; endoperidium 
subsessile, globose, often scabrid ; peristome prominent, coni- 
cal, sulcato-striate ; spores in the mass dark umber-brown, 
globose, verruculose, 4-5*5 ju, ; threads of capillitium simple, 
fusiform, 7-9 \x at the thickest part.

Endoperidium measuring when expanded from i|-2j inches. 
Distinguished from G. Bryantii by the much shorter pedicel 
which is not furnished with a groove at the apex, and from 
G. limbatus, by the absence of a pale silky zone surrounding 
the peristome. 
Tulostoma, Pers. (emended). 
Peridium subglobose, dehiscing by an apical aperture, outer 
coat (cortex) deciduous ; distinct from the elongated stem ; 
capillitium present, threads septate, swollen at the septa.

Tulasnodea , Fr. 
Resembling a Ly coper don with an elongated stem, but 
readily distinguished by the groove between the apex of the 
stem and the peridium, and the threads of the capillitium 
being nodulose at the transverse septa.
