REPORT OF THE STATE BOTANIST I905 25 



Living leaves of peppermint, Mentha piperita. Lake- 

 port, Madison co. July. 



The diseased tissue shrinks below the level of the surrounding 

 healthy tissue and eventually separates from it and falls away, 

 leaving circular holes in the leaves. 



Marasmius longistriatus n. sp. 



PLATE S, FIG. 1-4 



Pileus membranaceous, convex becoming plane with a central 

 depression or sometimes broadly infundibuliform, moist when 

 young and striate almost to the center, bay -brown when moist, 

 reddish gray when dry; lamellae thin, narrow, close, adnate, un- 

 equal, whitish; stem equal, externally cartilaginous, stuffed or 

 hollow, covered with a grayish downy pubescence which is some- 

 times longer at the base. 



Pileus 3-6 lines broad; stem 8-12 lines long, .5 of a line thick. 

 Under pine and hemlock trees. Bolton Landing. July. 



This resembles M. subnudus in color but it is a much 

 smaller plant with long fine striae on the pileus and with much 

 closer lamellae. The central depression resembles that of C o p - 

 rinus plicatilis. 



Melanogaster durissimus Cke. 

 Menands, Albany co. September 1904. A single specimen, 

 somewhat smaller than the type form and without the strong odor 

 attributed to that form, was found. Its hardness is remarkable, 

 and proves the appropriate character of the specific name. The 

 type form was found in India, but specimens of the species have 

 been reported from California by Dr H. W. Harkness. It is mani- 

 festly a species rarely found, but one having a wide range. 



Merulius pruni n. sp. 



Effused, thin, separable from the matrix, soft, with a definite 

 whitish or pallid scarcely byssin margin; folds forming angular or 

 irregular pores with dentate or sometimes irpiciform dissepiments, 

 ecru drab when fresh, darker or subcervine when dr^^ 



Bark of wild red cherry, Prunus pennsylvanica. 

 Horicon. July. 



It forms patches several inches long and broad, but these appear 

 as if formed by the confluence of many small orbicular patches, 

 the hymenium being faintly marked by concentric ridges or elevated 

 lines. The texture is soft and somewhat waxy yet slightly tenacious 

 and the margin is nearly glabrous. The specimens are sterile.
