spines at the apex ; these at length fall away, leaving a

Subgleba, occupying about one-fourth of the cavity. 



Spores and capillitium, olivaceous brown, the thread much 

 branched. Spores globose, with long persistent pedicels. 

 Scarce in the Valley. Found specimens in Albright's jungle.

Peridium, obovate or pear-shaped, with a profusion of 

 mycelium threads ; cortex with a thin coat of minute brownish 

 scales or granules, which are quite persistent. 



Subgleba, small, compact. 



Spores and capillitium, brownish olivaceous, threads thicker 

 than the spores. 



Growing in compact clusters ; so much so as to compress the inside 

 specimens out of shape. Equally common with the h. gemmatum all 

 through the Valley. This is about the only puff ball that grows on wood. 



I,. Wrightii. B. & C. 



Peridium, globose, sessile, white, minutely spinulose, 

 often converging at the apex. 



Subgleba, obsolete. 



spores and capillitium, greenish yellow, then brown oliva-

Genus X. SCIyE^RODERMA. Pk.
