Monilia crataegi Diedicke 



Parasitic on living leaves of various species of thorn bushes. It 

 causes the leaves to turn brown and die and is therefore more or 

 less injurious to the plant it attacks, according to the severity of 

 the attack. The fungus is at first whitish, but soon becomes ciner- 

 eous. When fresh it emits a strong odor. In the typical form of 

 the fungus the spores are said to be 13 p- long, 11 ij- broad. In 

 our specimens they vary from 12-20 ij. long, and 11-12 // broad. 

 Painted Post, Steuben co. Also Clayton, Jefferson co. and near 

 Albany. May and June. 



Myxosporium necans n. sp. 



Acervuli in longitudinal series, erumpent, whitish within, spores 

 oozing out in whitish or yellowish white tendrils or masses ; spores 

 oblong or elliptic, .00024-.0004 of an inch long, .00008-.000012 

 broad, often binucleate, supported on slender sporophores. 



Bark of living chokecherry, Prunus virginiana L. 

 North Greenbush, Rensselaer co. June. The fungus attacks the 

 trunk near the base and soon kills the shrub. 



Nolanea suaveolens n. sp. 



Pileus submembranous, convex, umbilicate, obscurely fibrillose or 

 unpolished, indistinctly striate on the margin, smoky brown ; lamellae 

 thin, unequal, close, adnate, whitish becoming dingy pink ; stem slen- 

 der, glabrous, hollow, brown; spores angular, uninucleate, .0004- 

 .0005 of an inch long, .00024-.0003 broad. 



Pileus 6-10 lines broad; stem 1.5-2 inches long, .5 of a line thick. 

 Woods. Sand Lake, Rensselaer co. August. 



The dried specimens emit an agreeable odor similar to that of 

 L a c t a r i u s c a m p h o r a t u s or L. g 1 y c i o s m u s. This 

 character is suggestive of the specific name.
