pale, smooth surface to the inner peridium. Subgleba small, 

 occupying scarcely more than a fourth part of the peridium ; 

 mass of spores and capillitium greenish-yellow, then brown- 

 ish-olivaceous ; the threads mostly thinner than the spores, 

 much branched; spores oval, even, 5-6 X 4-45 mic, usually 

 furnished with a short pedicel. Plate II, Fig. 3.

 and about i inch in height. This species is readily distin- 

 guished by its large oval spores. 



20. ly. CURTISII, Berk. Peridium globose, with a very 

 short rooting base and a .slender fibrous mycelium. Cortex 

 consisting of a pale 3'ellowish farinaceous layer, covered by a 

 coat of .soft, fragile white spines, curved and convergent at the 

 apex ; after maturity it soon disappears, leaving a pale smooth 

 surface to the inner peridium. Subgleba small, but distinct, 

 convex above and definitely limited ; mass of spores and 

 capillitium greenish-yellow, then pale olivaceous: the threads 

 long, simple, hyaline, two to three times as thick as the 

 spores ; spores globose, even, 3.5-4 mic. in diameter. Plate

Growing gregariouslj-, and sometimes caespitosely, on the

 This is L. Wrightii var. typicnin of Peck's U. S. species of 

 Lycoperdon. The peculiar characteristic of the species is the 

 hyaline threads of the capillitium : although they are of large 

 diameter, yet the walls are very thin and the threads collapse 

 in drying.
