THE ‘‘CRUCIATUM’’ SECTION. 
Spores olive, smooth. Cortex of short cruciate spines, peeling 
off in patches. 
Lycoperdon cruciatum the typical species, is very common in 
the United States, very rare in Europe and does not occur in Australia 
to my knowledge. 
LYCOPERDON STELLATUM. — Cortex of strong, thick, 
rugulose, connivent spines, peeling off in patches and leaving the peri- 
dium smooth. Gleba olive. Spores smooth, globose, 5 mic. Capilli- 
tium colored. 
This is a strongly marked species 
known from a single specimen at Kew 
(fig. 34) from Miss Brooks, Israelite 
Bay, Australia. The specimen is not 
cut open and we cannot say as to the 
sterile base but it seems to be scanty. 
The plant is evidently closely related 
to cruciatum but differs in the larger, 
rough cortex spines. 
THE “GEMMATUM” SECTION. 
Gleba olive. Spores small, globose, smooth or minutely rough. 
Columella prominent. 
Lycoperdon gemmatum and Lycoperdon pyriforme are the most 
common species that occur in the temperate regions of the world, and 
form a large part of all museum collections of puff-balls So numer¬ 
ous are they in the museums of Europe that we did not keep an item¬ 
ized account of the specimens and cannot remember whether or not we 
have noted typical specimens from Australia. Both are recorded from 
Australia, but neither has reached me direct from my Australian 
correspondents. 
LYCOPERDON GEMMATUM. -Cortex of soldered warts, like 
little “gems”, which fall away and leave scars on the peridium. Gleba 
olive. Columella prominent. Spores small (4-5 mic,) globose, min¬ 
utely rough, (almost smooth).
