Pores medium, small, round, 2-3 oiiu long with pale cinnamon tissue

spines arranged in longitudinal ribs, which are connected by a few 
transverse ribs.

comparison Just made with the spores of Polyporus leptopus from 
piece Kindly forwarded to me by Professor Patouillard shows the 
difference between the spores as found on comparison with those 
Polyporus renidens. I believe now that Polyporus^renidens from 
Brasil, the only specimen Known to me at Berlin, is the same as 
Polyporus leptopus, although the former is pleuropodial and_ the 
latter mesopodial. The only other species with these peculiar ridg¬ 
ed spores is Polyporus longipes, Known from a collection at Paris 
from French Guiana. Perhaps they are the same, but the collection 
differs much in general size and stipe insertion. 
HYHSHOGASTBR AREDARIUS, FROM MISS A. V. DUTKIE, SOUTH 
AFRICA (Fig. 1543).- T7e determined this from Tulasne Ls monograph 
which seems to agree though all such determinations should be con¬ 
firmed by comparison. The peridium is white, unchangeable. Gleba 
argus brown (Ri tigway). Spores smooth, lemon shaped as shown by 
Tulasne for Hymenogaster Bulliardii* Me present in our figures

they are not the same as shown by Bucholtz. Hence the determi¬

however, and some day we may learn whether Bucholtz or we made tne 
best guess as to its determination.
