Bovistella echinella (Pat.) Lloyd 



Plate 114 



Plants small, subglobose, 5-8 mm. thick, attached by a short, blunt, sandy pad; 

 when young, white with a thin, continuous, felt-like or granular cortex, at maturity 

 becoming dark brown and papery with scattered white flecks, in age practically de- 

 corticated. Mouth apical, definite, becoming fimbriated or toothed. Mature gleba 

 olivaceous brown, glebal chambers minute and irregular; subgleba practically none. 



Spores (of plant from Lapland) subspherical, 4.2-5.5//, apparently smooth but with 

 radial lines showing in the wall, furnished with slender, tapering pedicels up to 8.5// 

 long. Capillitium of separate units, but threads long and slender and less frequently 

 branched than in most species of this genus or of Bovista; main threads about 5.5// 

 thick. 



This little species has been collected in a number of widely separated places. The 

 original collection was from Ecuador, and we have specimens from North Dakota and 

 Lapland. Dr. R. E. Fries has also reported it from Lapland, and Lloyd reports it from 

 Michigan. This last is the only record, so far as we know, from the eastern United 

 States. 



We have examined a part of the original collection from Ecuador, kindly sent us by 

 Patouillard himself, and find it to be just like our collection from Lapland. The capil- 

 litium is of long, slender branched units with main threads only about 6.5// thick; spores 

 subspherical, 4-5.2 x 4.8-5.8// with slender pedicels up to 12.8// long, the walls of the 

 spores showing faint radial lines. Patouillard describes the spores as echinulate, but 

 we see only faint lines with no projection in optical section. 



Lloyd describes from Massachusetts Bovistella Davisii (Myc. Notes, p. 286, pi. 

 89), which from the description can hardly be distinguished from the present species. 

 We have not seen an authentic specimen.
