Spathularia flavida, Pers. 

 Variety rugosa has the club rugose. It was found iu the Adiron- 

 dack region growing in a circle about fifteen feet in diameter. All 

 the plants in the circle had the club or receptacle rugose. Some of 

 the plants were affected by Hijpocrea alutacea. The stems were quite 

 as velvety as iu the form described as Spathularia velutipes, C. & F. 



Sphserotheca pannosa, Lev. 

 Variety Rlhis occurs on the stems, fruit and leaves of wild goose- 

 berry, Rihes cynosbati. Bergen. June. It forms a dense felty stra- 

 tum of mycelium, which is white at first but soon becomes brown. In 

 the form on roses the mycelium, so far as I have observed, remains 

 white. I have received from Prof.. Scribner specimens of the same 

 variety which were found on gooseberry in Colorado. 



Hypoxylon Morsel, B. £ C. 



Dead branches of poison snmach, Rhus venenata. Gnilderland 

 station. May. If H. Blahei be united to this species, which nniou 

 some advocate, then H. Morsei is an inhabitant of alders, willows, 

 poplars and sumach. 



Sordaria coprophila, C. & D. 



In the early and immature condition of this fungus, the perithecia 



are thinly clothed with a minute cinereous flocculent villosity or 



tomentum, and the spores are cylindrical flexuous and colorless and 



very unlike the elliptical colored appendaged spore of the mature state. 



Sphaeria taxicola, Ph. 

 The spores in this are .0008 to .0009 in. long, .00016 to .0002 broad, 

 triseptate and colorless. Therefore the species should be referred to 

 the genus Metasphteria of the Saccardoian system.

NEW YORK SPECIES OF PLEUROTUS, CLAUDOPUS AND 



CREPIDOTUS. 



PLEUROTUS, Ft. 



Stem eccentric, lateral or none. Spores white. 



The species of this genus grow chiefly on decaying" woocl. A few 

 grow on the ground or are attached to mosses. They are very diverse 

 in size and general appearance. For instance, there is little resemblance 

 between P. ulniarius and P. striatnlus, the one a large species with a 

 - stout stem aTid thick fleshy pileus, the other a very small one with 

 no stem and a thin membranous pileus. Yet both are included by 

 the generic description. By reason of the lateral or eccentric stem 

 and of the tufted mode of growth of .some species, the pileus is often 

 very irregular and unsymmetrical. Some of the species are also very 

 variable in color, and among the small, at first resu])inate forms, the 

 5young plant is often, in appearance, very unlike the reflexed mature
