REPORT OF THE BOTANIST. 73 
- Exosastp1um Anpromep# Peck. 
Gall usually flattened or somewhat cup-shaped, more or less 
lobed, hollow, the cavity containing shreds of loose soft cottony 
filaments, smooth, pale green or green varied with red, paler and 
pruinose with age; spores narrow, oblong, simple, often curved 
near one end, white, .0007-.0009 in. long. 
Lateral or rarely terminal on living branches of Andromeda 
ligustrina, transforming the leaf buds. Center. May and June. 
_, Sometimes the dried blackened galls of the preceding year are 
round adhering to the branches in company with the new crop. 
The loose shreddy substance contained in the cavity of the gall is 
found by microscopic examination to be composed entirely of 
coarse irregular jointed filaments. 
Smaller but similar galls have been seen on a species of Vacci- 
nium at Center and one has been received from Florida, but I 
have not yet fully determined the characters of these. Hxobasv- 
dium Vaccinti Woronin, occurs in Europe on Vaccinium Vitis- 
Idea. It is perhaps worthy of remark that thus far these peculiar 
fungus galls have been observed on Ericaceous plants only.

LycoPERDON PEDICELLATUM Peck, 
Subpyriform, whitish, the outer peridium persistent, forming 
dense angular spinose processes which are smaller toward the base 
of the plant ; capillitium and spores greenish ochre or dingy oliva- 
ceous, the latter pedicellate, smooth, .00016-.00018 in. in diame- 
ter, the pedicel three to five times as long. 
Plant about one inch in diameter. 
Ground and rotten wood. Croghan and Center. September 
and October. . 
In shape this plant resembles the ordinary form of L. pyriforme, 
but the outer peridium is more coarse and shaggy than in that 
species. 
LycoPERDON SEPARANS 1%. Sp. 
Subglobose, sessile, white, the outer peridium forming dense 
pyramidal substellate warts which easily separate from the mem- 
branaceous inner one; capillitium and spores dingy olivaceous, 
the latter globose, smooth, .00016 in. in diameter. 
Ground in pastures and grassy places. Worcester. July.
