78 LACTARIAE OF THE UNITED STATES 
terra-cotta, usually paler than the pileus, sometimes spotted with 
reddish-brown, becoming darker where bruised, nearly equal or 
abruptly smaller at the base, glabrous or merely with a whitish 
bloom, firm, stuffed, becoming hollow in the mature plant, up to 
4.5 cm. long, 1-2 cm. thick; flesh tinted with terra-cotta ; spores 
whitish, subglobose, strongly echinulate, 7-8 и; latex white, | 
unchanging, astringent, then very acrid, abundant. (FIGURE 13.) 
Нав.: In moist grassy wood-trails and open places near 
brooks, or even in clay-banks by wood-road, in deciduous woods, 
oak and chestnut predominating. July, August, and September. 
DISTRIB.: New York, Peck (Long Island), Benedict (Staten 
Island) North Carolina, 1000-1400 meters elevation, Burlingham 
1, 1907 (type); Alabama, Baker. 
DISTINGUISHING FIELD-MARKS: The reddish-brick-colored zo- 
nate pileus with its short coarse pile-like tomentum, the madder- 
brown color of the mature gills, and the abundant white milk, 
which is very acrid after being on the tongue a moment. The 
margin of the pileus is usually marked with darker furrows, possi- 
bly from the pressure of the inrolled margin upon the gills. The 
Zones are sometimes obscure, but are more often conspicuous. In 
the dried plant the tomentum is inconspicuous. 
A few specimens of this plant were found August 30, 1904, near 
Smithtown, on Long Island, by Professor Peck, who from the first 
was inclined to regard it as an undescribed species. In the follow- 
ing summer one specimen was collected by Benedict on Staten 
Island. But in 1907 in the “ Pink Beds,” North Carolina, this 
was the most abundant mushroom throughout July and August. 
It is frequently gregarious and sometimes cespitose in habit. 1 
have seen as many as fourteen specimens growing within a few 
square feet. What has proved by comparison to be the same 
species was collected in Alabama in November, 1896, by C. F. 
Baker, but as it was accompanied by no field notes it was then im- 
possible to classify it. 
I take pleasure in naming this species Peckii in recognition of 
Professor Peck's extensive work upon the genus Lacfaria. 
The type specimens are in the herbarium of the N. Y. Bota- 
nical Garden.
