northern range only. It is much more common in Canada. In Europe 

 it is also a rare plant and of a northern range. The plant was named 

 by Prof. Peck Lycoperdon pedicellatum about 1875, and a year or so 

 afterwards, in Europe, by Schroeter as Lycoperdon caudatum.

FORM. BOVISTELLA GEMMATUM (Fig. 

 '126 ). \Ve have from R. H. Denniston, Madison, 

 Wis., a form with reduced, scabrous cortex (fig. 

 (126 enlarged), agreeing with tiie normal form in 

 all ether particulars. It may be only a sport. 



SPECIMENS IN OUR COLLECTION. 

 Wisconsin, R. H. Dennistcn. Fig. 127. 



BOVISTELLA DOMINICEXSIS (Fig. 127). Peridium glo- 

 bose, contracted to a short stem-like base. Cortex short, furfuraceous 

 (?),f falling away and leaving the surface smooth. Gleba olive. 

 Capillitium long, inter- 

 twined, colored threads. 

 Spores globose, 4-5 mic., 

 minutely spinulose, with 

 long pedicels (16-20 mic.). 

 (Fig. 127, type at Kew.) 



These specimens I 

 found in the herbarium at 

 Kew, labeled Lycoperdon 

 Dominicensis, in the hand- 

 writing of Prof. Massee. I Fig 12 s 

 think it was never published. 



The specimens were collected by the "West Indies' Exploration Com- 

 mittee," on the island of Dominica. It is very close to the preceding 

 species but differs in having rough spores. These are very minutely - 

 echinulate, however, and appear smooth except under a strong ob- 

 jective. 



Section 3. Bovistella-Bovista. 



Capillitium short, separate, branched threads. Spores pedicellate. Sterile 

 base none. 



This section is very close to the genus Bovista from which it differs in habits. 



|We can not be sure but that the plants have had stronger cortex spines that have fallen 

 away. There is a sketch with the plant showing such spines, but we think it is not authentic.
