The following species while answering perfectly to the fun¬ 
gus named and described by Tode differs altogether in its micro¬ 
scopic detail from Pezicula carpinea Tul. 
Dermatella scotinus Morgan sp. nov.—Apothecia erump- 
ent-caespitose, fleshy-fragile, subturbinate, whitish or alutaceous; 
the disk plane or convex, farinaceous. Asci cylindric, with a 
short stalk, paraphysate, 4-8-sporous, the spores obliquely uniser- 
iate, 150-170 x 15-20 mic.; spores at first oblong, hyaline and 
continuous, becoming inaequilateral or slightly curved and trans¬ 
versely 1-3-septate, finally brownish with occasionally one to 
three oblique or longitudinal septa, 25-30 x 10-12 mic. 
On Carpinus americana, growing out of the inner bark 
through the periderm; Preston, O. December, 1897. The apoth¬ 
ecia .5-1.0 mm in diameter, more or less irregular from the 
mutual pressure, few to several in each tuft. The asci may con¬ 
tain eight immature spores, but they do not appear to mature all 
of them. This species belongs in the second section of Der¬ 
matella along with Dermatella fagi (Phillips). 
A NEW EGG PLANT FUNGUS. 
CLAYTON O. SMITH. 
During the month of September and October, what has 
proved to be a new egg-plant disease, made its appearance in 
certain parts of Delaware. For some time it was thought to be 
Phyllosticta hortorum Speg., reported by Halsted as found in 
New Jersey on Solanum mclongena L. A careful comparison 
with Halsted’s material showed the two to be distinct. It is 
quite probable that these two have been confused with each other. 
Ascochyta lycopersici Brun. Spots occurring both on the 
leaves and fruit of Solarium melongena, Leaf-spot 0.5-2 cm. and 
more in diameter, subcircular or irregular, reddish brown some¬ 
times with a darker colored center and often with a darker mar¬ 
gin, the zone between being of a lighter color. Dark concentric 
ridges of elevated plant tissue are generally present. Fruit spot 
large 2-10 cm. or more in diameter, of the same color as rind of 
fruit or often a pale flesh color with darker zones. Perithecia 
submerged forming at first slight elevations in the tissue, at 
length superficial, black, scattered; spores guttulate with oil 
drops and continuous, but at length uniseptate, hyaline, slightly 
constricted at septum, 6-12 x 3.5-4^. 
This fungus differs from Phyllosticta hortorum Speg. both 
in size and septation of spores and in character of leaf spot. 
The spores of Phyllosticta hortorum Speg., in material col¬ 
lected by Halsted, agree in size with those as given by Saccardo, 
4-6 x 2-2.5/x while those in this Ascochyta are nearly twice that 
size, 6-12 x 3.5-4 fi.
