152 THIRTY-FIFTH REPORT ON THE STATE MUSEUM. 
CUTICLE OF THE PILEUS DRY. 
PROCERI. 
Annulus persistent, movable, distinct from the volva. 
This tribe is distinguished by its species having a well-developed 
annulus,. which soon breaks loose from its attachment to the stem and 
thus forms a movable ring upon it, and a distinct cavity or depression 
in the pileus beneath the umbo for the reception of the stem. 
The only representative thus far found in our State is A. procerus, 
but A. rhacodes, A. excoriatus, A. mastoideus and A. Morgans have 
been reported from neighboring States and will probably yet occur in 
our limits. All the European species of this tribe are classed by Fries 
as edible. 
AGARICUS PROCERUS, Scop. 
Tall Agaric. Parasol Mushroom. — 
Pileus at first ovate, then broadly convex or expanded, strongly 
umbonate, scaly or spotted from the breaking up of the cuticle, whitish 
alutaceous or brownish, the deflexed margin generally silky-fibrillose, 
the flesh soft, white; lamelle close, free or remote, whitish, sometimes 
tinged with yellow or pink ; stem fall, cylindrical or slightly tapering 
upward, bulbous, hollow, squamose or furfuraceous, colored like the 
pileus, sometimes spotted, the annulus thick, firm, movable, white ; 
spores large, elliptical, -00055 —-0007’ long, -00035—- 00045’ broad. 
Plant 5'—10’ high; pileus 3—6’ broad; stem 4’—6" thick. 
Fields, pastures, roadsides and occasionally in woods. July to Sep- 
tember. 
This Agaric resembles a parasol in shape, whence the popular name. 
It is easily distinguished from the allied species by its long stem, 
movable ring and prominent umbo. Generally the scales of the pileus 
are rather broad and distant from each other toward the margin, but 
closer toward the umbo on which the cuticle usually remains unrup- 
tured. For this reason the umbo is generally darker colored than the 
rest of the pileus. Sometimes the scales are appressed and spot-like, 
again they are slightly reflexed and then they give a rougher appearance 
to the pileus. They may be brownish, tawny-brown or reddish-brown 
in color. They often disappear almost wholly from the margin of the 
pileus which then has a whitish silky appearance. The stem is 
remarkable for its great length when compared with its thickness and 
is suggestive of the specific name, procerws. In extreme cases it is 
nearly or quite a foot long, though rarely more than half an inch thick. 
In a dried specimen before me the stem is nine inches long and one- 
fourth of an inch thick. The surface of the stem is in many cases
