ExoBA^siDiuM Andromeda Pech, 



Gall usually flattened or somewhat cup-shaped, more or less 

 lobed, hollow, the cavity containing shreds of loose soft cottony 

 filaments, smootli, 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 

 found 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 Yacci- 

 nium at Center and one has been received from Florida, but I 

 have not yet fully determined the characters of these. JExolasi- 

 dium Yaccinil Woronin, occurs in Europe on Yaccinium Yitis- 

 Ida&a, It is perhaps worthy of remark that thus far these peculiar 

 fungus galls have been observed on Ericaceous plants only. 



^THALIUM FeRRINCOLA Schw, 



Iron rails of railroads. Worcester and Schenevus. July. 



Geaster Bryantii Berh. 

 Ground. Schoharie. 



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. pyri forme, 

 but the outer peridium is more coarse and shaggy than in that 

 species. 



Lycoperdon separans n. 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.
