50 THIRTIETH REPORT ON THE STATE MUSEUM. 
LYCOPERDON SACCATUM FA’. 
Ground. Sandlake and Center. Autumn. 
AMAUROCHATE ATRA A. & SN. 
Trunks of pine trees. Adirondack Mts. August. 
PHYSARUM LUTEOLUM 7. sp. (Plate II, figs. 15-18.) 
Peridium small, closely gregarious, sessile, yellowish inclin- 
ing to tawny, rupturing irregularly ; flocci abundant, yellow- 
ish-white ; spores globose, purplish-brown, .0004’ in diameter. 
Living leaves of Cornus Canadensis. Adirondack Mts. 
July. 
PHYSARUM ALBICANS 7. sp. (Plate II, figs. 5-8.) 
Peridium whitish, fugacious, except at the base, externally 
mealy with lime granules, globose, as well as the more persist- 
ent whitish capillitium ; stem white, tapering upwards, some- 
times connate at the base, slightly penetrating ; spores globose, 
purplish-brown, .00033' in diameter. 
Bark and mosses. Adirondack Mts. July. 
The fragments of the base of the peridium sometimes remain 
just below the capillitinm, surrounding the stem like a calyx 
or collar. The stem is even and generally longer than the 
peridium which it penetrates. After the spores have fallen the 
whitish color of the capillitium becomes apparent. It then 
resembles a small globose tuft of wool. The plants grew on, 
the branches and mosses of a standing dead birch tree. 
Didymium subroseum is apparently the same species with a 
pinkish tinge to the peridium. 
DIACHHZA SPLENDENS 7. sp. (Plate II, figs. 1-4.) 
Peridium steel-blue or violaceous, delicate, globose, subper- 
sistent, rupturing irregularly ; flocci delicate, colored; stem 
white, slightly penetrating ; spores black in the mass, globose, © 
rough, .0003—.0004' in diameter. 
Fallen leaves and twigs. North Greenbush. October. 
This is a very pretty and distinct species. The globose 
peridia and rough spores make it easily recognized. It is near 
D. elegans in color, but at once distinguished from it by its 
globose peridium.
