90 TWENTY-SIXTH REPORT ON THE STATE MUSEUM. 
AGARICUS GALERICULATUS 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 lamelle and a very long 
stem generally of a delicate pink color toward the top. It might 
be called var. ongipes. 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 Fisuta 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. 
AGARICUS GEOPHYLLUS Sow, 
The variety with the pileus of a beautiful lilac color oeeurs in 
Bethlehem. It is Ag. afinis Pers. and might appropriately be 
named var. lilacinus. . 
Marasmivs ve.tutipss 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 planta distinct 
species, yet so nearly related to J/. velutipes that the absence of 
an umbilicus is the only available mark of distinction ? Onur plant 
sometimes grows in lines or rows several feet in length.

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 Sprague: B. & C., 
since published, is a very closely related species, if indeed it be 
specifically distinct. 
Potyrorus BoucnEanus 7. 
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. Loucheanus 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. J 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
