BULGARIA BICOLOR 7. sp. (Plate IT, figs. 4-6.) 
Cups irregular, expanded, sessile, appressed, about an inch broad, externally 
gelatinous, whitish or subolivaceous, the disk reddish-brown or dark watery- 
chestnut; asci cylindrical; spores uniseriate, elliptical, .0009'—.0011' long, 
.00045'—.0005' broad ; paraphyses filiform, thickened at the tips, brownish. 
Wet decaying birch wood  Brewerton. Sept. 
The spores are generally furnished with one or two large nuclei. The con- 
trast between the dark color of the disk and the light color of the cup suggests 
the specific name. 
BULGARIA DELIGATA 7. sp. (Plate II, figs. 1-3.) 
Cups small, 1-2'' broad, plane or convex, scattered or crowded, sessile, 
the margin obliterated, purplish-black when moist, black and more or less 
angular when dry, surrounded at the base by whitish filaments which bind 
them to the matrix; spores elliptical, uniseriate, binucleate, .001/—.0013/ 
long, .0006'—.0007' broad; paraphyses numerous, filiform, thickened above, 
slightly colored. 
Wet decaying hemlock wood. Catskill Mountains. July. 
The numerous white filaments that appear to bind the cups to the matrix, 
constitute a marked feature in this species, and suggest the specific name. 
Exoascus Pruni /ckl. 
Immature fruit of sand cherry and wild plum, Prunus pumila and 7’. 
Americana. Center and Carlisle. May and June. Also Buffalo. CZinton. 
When the fruit of the sand cherry is attacked by this fungus, it enlarges 
in size, becomes elongated and pointed, soft and discolored. Sometimes it 
assumes a bright-red hue, but usually a pale whitish-green or yellowish-green 
varied somewhat by red or pinkish tints. The pit even is destroyed, and the 
whole texture of the pulp is changed. Rarely the leaves also are attacked, 
in which case they become swollen, distorted and discolored. 
The fruit of the wild plum, when attacked, becomes enlarged and soft, and 
assumes a whitish or pale green color, but does not become elongated or 
pomted. Of course, its value asa fruit is wholly destroyed. At Carlisle, one 
tree was observed which had been cultivated in a court-yard, and which had 
all of its fruit affected by this fungus.

The propriety of keeping this and the preceding species generically dis- 
tinct is perhaps doubtful, but I give the names as I find them. 
HyYPpoMyYces LUTEOVIRENS Fr. 
On decaying Russula. Center. Sept. 
Thé spores in our specimens are longer than required by the description of 
the species to which we have referred them. They are .0012-.0015' in 
length, acuminate at each end, and at length uniseptate. The asci are very 
long and slender,
