90 Twenty-sixth Report on the State Museum, 



Agakicus galerictjlatus Scop. 



Two well-marked varieties of this very variable species were 

 observed the past season. One grows on the ground among fallen 

 leaves. It has a dark-brown pileus, close lamellae and a very long 

 stem generally of a delicate pink color toward the top. It might 

 be called var. longipes. The other grows under pine trees, has a 

 broadly convex or expanded grayish-brown pileus and a short 

 stem. It might be called var, expansus. 



Agaricus Fibula Bull. 



A form of a pale color with the center of the pileus and the 

 upper part of the stem brown occurred on mossy logs in woods at 

 Worcester and Croghan. July and September. 



AgAEICUS GEOPHTLLrS SoW. 



The variety with the pileus of a beautiful lilac color occurs in 

 Bethlehem. It is Ag. affinis Pers. and might appropriately be 

 named var. lilacinus. 



Marasmius velutipes B. (& C. 



This with us is one of the most common species of the genus, 

 occurring in all our woods and wooded swamps, but I have never 

 been able to find it with an umbilicate pileus. Can it be that 

 there are two forms, one northern with a convex pileus, the other 

 southern with an umbilicate pileus? Or is our plant a distinct 

 species, yet so nearly related to M. "celutipes that the absence of 

 an umbilicus is the only available mark of distinction ? Our plant 

 sometimes grows in lines or rows several feet in length. 



BOLETUS^PICTUS PTc, 



This plant was erroneously described in a former report as 

 '' viscid when moist." Subsequent observations satisfy me that it 

 is not viscid even in the moist state. Boletus Spraguei B. & C, 

 since published, is a very closely related species, if indeed it be 

 specifically distinct. 



POLYPORUS BOTJCHEANUS Ft. 



The American plant commonly referred to this species is quite 

 variable and has been a source of considerable perplexity. It has 

 been ascribed by eminent mycologists to Polyporus, Favolus and 

 Hexagona, and Fries in his Epicrisis places P. Boucheanus in the 

 section Pleuropus, while Berkeley, in his Notices of N. A. Fungi, 

 puts it in the section Mesopus, though he adds the remark that it 

 is frequently pleuropous. I have seen very many American speci- 

 mens of our so called P. Boucheanus^ yet in but a single instance 

 have I seen it with a central stem. There are three prominent 

 points of disagreement between our plant and the description of 

 P. Boucheanus in the Epicrisis. The stem does not become
