72 Twenty-sixth Report on the State Museum. 



Stekeum tenereimum B. (& R. 



Mossy ground. Indian Lake and Croghan. September and

I have seen no description of this species, and depend, for the 

 correctness of the determination, upon a comparison of our speci- 

 mens with authenticated ones received from the late Dr. Curtis.

 brown ; hymenium uneven, marked with thick corrugations or

ExoBAsiDiuM Azalea Peck. 



Gall subglobose, often lobed or irregular, succulent, fleshy, 

 solid, smooth, pale green or glaucous, becoming pruinose ; spores 

 oblong, straight or curved, obscurely uniseptate, white, .0006- 

 .0008 in. long. 



Terminal on living branches of the pinxter plant, Azalea nudi- 

 jiora^ transforming the flower buds. 



North Greenbush and New Scotland. May and June. 



These fungus galls are usually from one to two inches in diame- 

 ter and appear cotemporaneously with the blossoms of the shrub 

 they inhabit. They are known in some localities by the name 

 "May apples" and not being unpleasant to the taste they are 

 sometimes eaten by voracious school boys. Upon attaining their 

 full size they soon become dusted by the white spores which are 

 borne upon the apices of minute filaments projecting slightly from 

 the whole surface of the gall.
