Pileus rather fleshy, ovoid to expanded, sometimes broadly um- 
bonate, solitary or cespitose, 5-8 cm. broad ; surface fulvous to 
isabelline with intermediate shades, darker on the umbo, covered 
when young with appressed, matted fibers, which may disappear 
with age or collect into small squamules, the cuticle cracking 
areolately at times, margin not striate; context very thin, con- 
colorous, the taste mild or slightly disagreeable, the odor not 
characteristic ; lamellae rather crowded, sinuate-adnexed or ad- 
nate, somewhat ventricose, yellowish, shading to umber and spot- 
ted with black and rusty-brown as the spores mature, whitish on 
the edges; spores nearly lemon-shaped, apiculate, opaque, tuber- 
culose, very dark brown under the microscope, black in mass, 
8-10 X 4-6 /i; cysidia abundant, 40 X 9 ai; stipe equal or slightly 
enlarged below, subconcolorous, nearly white at the apex, hol- 
low, 5-10 cm. long, 8-12 mm. thick; veil of whitish, fibrous tufts 
adhering partly to the margin and partly to the stipe. 
This species is not uncommon in many parts of the eastern 
United States and Europe, in grass or weeds in the open or 
among leaves or about old stumps in thin woods, appearing from 
the middle of June to October in this latitude. It comes up reg- 
ularly on my lawn each year, sometimes solitary and sometimes in 
dense clusters, but always attractive because of its splendid color- 
ing and its peculiar “ weeping ” character. Its surface charac- 
ters vary considerably with age and weather conditions. I have 
not tested its edibility. 
The history of this species is rather confusing. It was orig- 
inally described by Bulliard as Agaricus lacrymabnndus and fig- 
ured by him and by Sowerby. Persoon gave it a new name, Agar- 
icus velutinus, which Fries reduced to a variety when he took up 
Bulliard’s name, but later, in figuring the species. Fries emphasized
