Cop. atramentarius, noted for the whole plant dissolving in 
age into a black inky fluid—came about the same time and was 
smoky or silvery gray in color. The most striking Coprinus 
however is C. comatus—tall, barrel-shaped, and covered with 
shaggy scales,—and this species to a mycophagist, is a dainty 
morsel. 
Among other dark-spored species, we found abundant Hy- 
pholoma, both the common creamy H. appendiculatum and the 
brick-red H. sublateritiwm— lasting from May to October. 
Stropharia semiglobata was not uncommon, but its relative 
S. aeruginosa was a dainty rarity with its delicate robin’s-egg 
blue cap and pale chocolate gills. 
In this brown spored division is also the genus Agaricus: 
Agaricus campestris being the common mushroom of culture 
caves and shops. In the latter part of summer came an interesting 
series of Agarici—the broad-topped, delicately scaly species pla- 
comyces, the horse-mushroom A. arvensis, the delicate little wood 
form, A. silvicola, and the fine, stout, crimson-gilled A. rod- 
mani. It is especially interesting with mushrooms, so difficult at. 
best to determine accurately,—to be able to examine a series of 
related species and note the minor points of difference together 
with the typical characters of the genus. 
The largest group of Agarics is the section having white 
spores. Here we studied the most poisonous of all mushrooms, 
the Amanitas, and found numerous species: the beautiful A. 
phalloides, pure white or tinted with gray or buff; tall, with 
graceful white collar and distinct cup at base. Some of these 
we watched with great interest, developing from the egg. Close- 
ly related is the smaller A. verna, called the destroying angel—its 
exquisite purity together with its fatal principle giving sufficient 
warrant for the poetic term. 
Then A. virosa, A. velatipes, (properties untested but prob- 
ably vicious), the little 4. floccocephala, the bright orange A. 
muscaria called the fly-mushroom, and the reddish-tinted A. ru- 
bescens. Amanitopsis is closely related and lacks only the collar 
on the stem; we found that with gray and salmon-tinted caps. 
Next in order of relationship comes Lepiota the parasol
