REVISION OF POLYSACCUM. 
Peridium smooth, even, or rather tuberculose, fragile, dehiscing 
irregularly, reddish-brown, tinged olive, 1-3 in. diam. Sowerby’s 
plant is undoubtedly this species, and was at the time correctly re- 
ferred to the fig. of Alb. and Schw. given above, which in turn is 
synonymous with P. pisocarpium. 
On the ground in sandy places. Europe, N. America, Australia, 
New Zealand. 
P. boreale, Karst., Myc. Fenn. (Basidiomycetes), p. 363. 
Peridium subsphieroid or obovoid, substipitate, white. Peridiola 
irregular, oblong, 2x3 mm. Spores spherical, echinulate, brown, 
8-13 p. Karst. Fung. Fenn., Exs., 570. 
The specimen in the Kew Herbarium from Karsten is altogether 
white externally, and the spores coffee-colour, with a tinge of 
purple in the mass. Related to P. pisocarpium . 
Amongst sand. Pudasjarvi (lat. 65^°). 
P. microcaxpum, Cke. $ Mass. 
Peridium subglobose, coarsely tuberculate, ochraceous brown ; 
stout, short stem-like base, bright citrin. Peridiola small, angular, 
about 2 mm., septa very thin and fragile. Spores spherical, 
minutely warted, ochraceous, with a tinge of olive, 6-7 p. 
Related to P. pisocarpium , but distinct in the size of the peri- 
diola and spores, and also in the colour of the latter. Peridium 
from 1J-2 in. diam. 
Torvoomba, Queensland. 
P. crassipes, D. C. ; Voy I., p. 8 ; Flor. Fr.. vi., p. 103. 
Peridium varying from spherical to clavate or subcylindrical, 
stem-like base, stout, often lacunose. Peridiola minute, oblong or 
polyhedral, about 2 mm., golden yellow, then ferruginous. Spores 
spherical, warted, coffee-colour, 9-12 p. Fries S. Myc. iii., p. 53.
