REPORT OF THE BOTANIST. 10? 



MlTRULA IJ5TFLATA 8c7lW. 



Decaying wood and bark of trees. Catskill Mts. and Wor- 

 cester. July and August. 

 I have never found this plant fertile. 



Peziza adtjsta G. & P. 



Gregarious or scattered ; cups subglobose, then open and 

 hemispherical, at length flattened, one line broad, somewhat 

 irregular when dry, brown externally, with a few radiating 

 white filaments at the base ; disk amber-colored or yellow- 

 ish, darker when dry, nearly plane or slightly concave ; 

 asci cylindrical ; spores elliptical, binucleate, .0007' long, 

 . 0003' broad ; paraphyses clavate, brownish. 



Burnt ground under pine trees. West Albany. July. 



Peziza subcarkea C. & P. 



Scattered, stipitate, small ; cups at first clavate then 

 infundibuliform, wholly flesh-colored ; stem long, attenu- 

 ated at the base, expanded above into the cup ; margin con- 

 tracted, paler ; asci cylindrical ; spores linear, obtuse, 

 hyaline. 



Dead liverworts on old logs in woods. Indian Lake. July. 



The liverworts die in suborbicular patches which are some- 

 times several inches in diameter. On these patches of dead 

 plants the fungus grows. The inference is that the fungus 

 causes the death of the liverwort. The species is closely 

 allied to P. piriformis. 



Ascobolus pilosus Fr. 



Dung of deer. Adirondack Mts. August. 



Helotium acicttlare Fr. 



Decaying half-buried wood. Adirondack Mts. August. 



Helotium fastidiosum n. sp. 



Gups small, convex or plane, stipitate, pale yellow or 

 whitish ; stem slender, about equal in length to the diam- 

 eter of the cups, brownish or yellow with a brownish base ; 

 asci narrowly clavate ; spores crowded or biseriate, elon- 

 gated, subclavate, multinucleate, .001' long, about .0002' 

 broad, sometimes slightly curved. 



. Petioles and midribs of fallen alder leaves in wet places. 

 Forestburgh. September.
