L. pedicella'tum Pk. pedicidus, a little foot. Peridium %-iK in. 



in diameter, globose or depressed- 

 globose, sessile or narrowed below 

 into a stem-like base, whitish or ci- 

 nereous, becoming dingy or smoky- 

 brown with age, echinate with rather 

 dense spines which are either straight, 

 curved or stellately united and which 

 at length fall off and leave impressions 

 or obscure reticulations on the sur- 

 face ; capillitium and spores greenish- 

 yellow, then dingy-olive, columella 

 present. Spores smooth, pedicellate, 

 4 4-5/A in diameter, the pedicel three 

 to five times as long.

 The pedicellate spores constitute the peculiar feature of this species. 

 It is one which suggests the name and which enables the species to be 

 easily distinguished from all its allies. The spore is terminally and per- 

 sistently attached to the pedicel, as in some species of Bovista. The 

 plant is sometimes sessile, but usually it is narrowed below into a stem- 

 like base. In the immature state it has a rough, shaggy appearance, 

 but the spines shrivel with age so that it appears less rough when old. 

 The pitted surface of the denuded peridium affords a mark of distinc- 

 tion from L. echinatum. L. pulcherrimum B. and C. is evidently the 

 same species, but the name here adopted has priority of publication.
