lose Alga. The spores are of a rich red brown, and are very 
minutely echinulate. The flocci, towards the top of the 
peridium assume a yellowish tinge. The inside of the peri- 
dium, as in Fries’ Bovista suberosa, which is doubtless the 
same thing, is purplish brown. Bovista suberosa, Rostkovius 
is clearly not the same with Fries? plant.*

The very young spores have a short peduucle.

24. Lycoperdon letum, Berk. ; peridio subcoriaceo rimoso- 
areolato demum cupulari-aperto; strato sterili stipitiformi 
celluloso, capillitio sublenticulari subtus excavato sporisque 
luteis, demum fuligineo-luteis. Zeyher, n. 103.

About 14 inch high, 1$ broad. Stem 2 of an inch high, 
1 inch thick, obese, incrassated above, consisting of a rigid 
pale reddish-brown, cellular, spongy substance, externally 
reddish brown, sulcate, clothed with minute furfuraceous 
warts; sometimes more or less obsolete. Peridium subglo- 
bose or lenticular, pale, coarsely cracked, areolate, at first 
clothed with short pyramidal warts, at length nearly or quite 
smooth, opening irregularly. Capillitium sublenticular, hol- 
lowed beneath yellow ; flocci, pellucid, branched, not rough ; 
spores, minute, globose, perfectly even, with a minute, cen- 
tral nucleus, stemless, or very shortly pedicellate, yellow, in 
older plants yellow- olive. 
This species, which is very peculiar, has more the appear- 
ance of a Scleroderma than of a Lycoperdon, though its struc- 
ture is that of the latter. It resembles, in some respects, 
Lycoperdon celatum. The peridium is, however, more rigid, 
and opens, apparently, not by the mere collapsion of the cen- 
tre, but by coarse cracks. It varies with a distinct stem, and 
* I have a specimen of Scleroderma, from Dr. Montagne, with pre- 
cisely the habit of Desvaux’s Mycenastrum. The distinctive characters of 
the genus must then be taken from the Capillitium. There is a third spe- 
cies from Chili in Dr, Montagne’s Herbarium.
