28 THIRTY-SECOND REPORT ON THE STATE MUSEUM. 
Plant 2/-5’ high, pileus 1 —3' broad, stem 2/—4'' thick. 
Decaying wood. Catskill Mountains and Gansevoort. July and August. 
AGARICUS UMBROsUsS Pers. 
Decaying wood. Indian Lake. Aug. 
Agaricus (ENTOLOMA) DYSTHALES 7. sp. 
Pileus submembranaceous, subconical, then conyex or expanded, obtuse, 
striate, furfuraceous or squamulose, lurid-brown, becoming paler with age; 
lamellz broad, subdistant, ventricose, brown or grayish-brown, then flesh- 
colored ; stem equal, hollow, slender, tomentose-squamulose, brownish ; spores 
irregularly oblong-elliptical, .0006/—.00065' long, about half as broad, usually 
containing a single large nucleus. 
Plant about 2! high, pileus 3’—6” broad, stem about 1 thick. 
Damp ground in woods. Catskill Mountains. July. 
The species belongs to the section Leptonidei. It has a peculiar starved 
deformed appearance, whence the specific name. To the naked eye the pileus 
appears to be clothed with minute branny scales, but under a lens these are 
seen to be jointed matted filaments which form a kind of thin squamulose 
tomentum. In some specimens it is more dense than in others, both on the 
pileus and stem. The general outline of the spores is narrowly elliptical, but 
they are somewhat pointed at the base and they also have the angular pro- 
jections, which are generally present on the spores of species of Entoloma. 
The adornment of the pileus and stem indicates an affinity with A. jubatus, 
but our plant is much smaller than that and is very different in its habit. 
AGARICUS MURICATUS F7. 
Decaying wood of deciduous trees. Carlisle and Indian Lake. June and 
August. 
AGARICUS TRECHISPORUS Berk. 
Ground in woods. Brewerton. Sept. 
Only a single specimen was found. The pileus is nearly white and the 
plant odorless, but in other respects it agrees well with the description of the 
species to which we have referred it.

Agaricus (INocYBE) NODULOSPORUS 7. sp. 
Pileus thin, hemispherical or convex, obtuse, floccose-squamose, dark 
cervine-brown or umber color, the scales of the disk usually erect ; lamelle 
rounded behind, adnexed, ventricose, pallid, then ferruginous-cinnamon, white 
and minutely toothed on the margin ; stem equal, solid, tomentose-squamulose, 
colored like the pileus; spores rough, .0003’-.00035! long. 
Plant about 1’ high, pileus 4-8” broad, stem scarcely 1/’ thick. 
Decaying wood in woods. Gansevoort. Aug. 
This species agrees very closely with the description of A. lanuginosus, to 
which I should have referred it but for the rough spores. It is smaller than 
A. stellatosporus, of a paler color and a more soft and woolly appearance. 
Both belong to the section Squarrosi.
