Plate 88. Figs. 22 and 23. Balansia discoidea P. Hen¬ 
nings, on stem of Chloris distichophylla, Brazil. 
Fig. 22, real size, pseudosclerotium and stromata at a. 
Fig. 23, same magnified 3 times real length and width. 
Fig. 24, Balansia discoidea P. Hennings, on stem of Andro- 
pogon, Kansas, magnified 3 times the real length. 
Figs. 25-27, Dothichloe atraemntosa (B. & C.) Atkinson. 
Fig. 25, photograph, real size, of Andropogon plant from 
Alabama showing black effuse stromata on under side of the 
leaves. This plant indicates that when the host and fungus were 
young the young stroma entirely surrounded the cluster of 
leaves, but when the leaves elongated they tore the enveloping 
stroma apart. 
Fig. 26, a single stroma on under side of a leaf magnified 
3 times the real length and width. 
Fig. 27, photograph magnified 3 times the real length and 
width of very thin stroma on leaf of grass, of No. 683 E. & E. 
N. A. F. This is the same form as occurs in Rav. F. C. Ex. 
No. 100 which usually bears the name “Dothidea atramentaria 
B. & C.” See text for discussion. 
Figs. 28, 29, Dothichloe aristidae Atkinson, on stems of 
Aristida purpurascens, Alabama. 
Fig. 28, real size. 
Fig. 29, magnified three times the real length and width. 
Note that the perithecia are larger and much more prominent 
in Fig. 29 than in Fig. 20 where they do not show because not so 
prominent.

ANOTHER FLY AGARIC. 
D. R. SUMSTINE. 
Amanita muse aria is called the fly agaric because infusions 
of it are poisonous to flies. It has now, however, a keen rival 
for this reputation in another species of the same genus. Last 
summer while drying specimens of Amanita g)litaria Bull, a num¬ 
ber of flies were attracted to them. After thedlies had remained 
on the plants for a short time they fell over apparently dead. This 
continued until thirty-nine fly mycophagists had become the vic¬ 
tims of some narcotic contained in the mushrooms. The box with 
flies and plants was then set aside for future study. After two 
hours the box was again examined, but the flies which once were 
dead were now alive and had departed with no more serious 
results possibly than a severe headache from their mycological 
■“booze.”
