58 THIRTY-SECOND REPORT ON THE STATE MUSEUM. 
Peronospora Viticota B. & C. 
Leaves of wild grape-vines. Catskill Mountains. A Peronospora which 
is scarcely distinguishable from this species occurs about Albany on leaves of 
the great ragweed, Aibrosia trifida. 
MorcHELLA SEMIi.IBERA DC. 
Mr Warne finds two forms of this species at Oneida, one with the pileus 
conical, the other with it hemispherical and obtuse. In both the stem may be 
either short or long. The pileus is often free nearly or quite to the apex. 
GyRoMITRA ESCULENTA FY. (Helvella esculenta.) 
This plant sometimes grows so large that a single one will weigh a pound. 
HELVELLA ELAstica Bull. 
This species is described as having the pileus free. It is not uncommon to 
find it with the pileus attached in one or two points to the stem. 
VERPA DIGITALIFORMIS Pe7s. 
Buffalo. Clinton. 
HeELoTIUM PILEATUM PA. 
Decaying stems lying in water. Sandlake. May. 
ying ying Mf 
This is a large form about an inch high, with a conical or subcampanulate 
pileus 2 '-.3!’ broad. 
VaLsa Oxyspora PA, 
The habitat of this species was, by an error, stated to be dead oak branches. 
It is dead branches of mountain holly, Nemopanthes Canadensis. I have 
not found it on oak. It is very distinct from V. faleola, if the published 
characters of that species are at all reliable.

NEW YORK SPECIES OF LYCOPERDON. 
LycopERDON Tourn. 
Peridium membranaceous, vanishing above or becoming flaccid; bark 
adnate, subpersistent, breaking up into scales or warts; capillitium soft, dense, 
adnate to the peridium and sterile base. Syst. Myc., Berk. Ouil., Cooke's 
Handbook. 
The species of Lycoperdon are commonly known as “ Puff-balls.” They 
belong to a family of fungi called Gasteromycetes, because of their habit of 
produci ing their spores in the inner cavity of the plant. The particular order 
to which “they belong is called Trichogasters, a name having reference to the 
hair-like filaments with which the interior of the mature plant is filled. 
These filaments form a somewhat elastic mass, and are interspersed with vast 
numbers of minute dust-like spores. When, therefore, the mature plant is
