PLANTS PREVIOUSLY REPORTED— REMARKS AND 
OBSERVATIONS. 
The first twelve species of fungi here given were reported without 
description. They are now repeated with descriptions. 
Dornier cLavispora. (Hysterium clavisporum C. & P.). 
Stroma small, oblong, elliptical or linear, at first covered by the 
epidermis, then erumpent, longitudinally striate under a lens, black ; 
asci clavate; spores crowded, clavate, multiseptate, colored, .Q01”— 
.0013' long. 
Dead stems of Phragmites communis. 
The fungus frequently grows in long lines or series. Mature 
fruit-bearing specimens especially occur on the older and more dis- 
colored stems. The septa are from five to nine, the intervals between 
them being very short. The basal cell is usually the longest. 
Hysterium ExaripuM C. & P. 
Superiicial, seated on irregular bleached spots ; perithecia elliptical, 
minutely rugose, opaque, black ; lips elevated, paler, connivent ; asci 
clavate; spores filiform, hyaline. 
Fallen leaves of Kalmia angustifolia. 
Cotpoma JuniperinuM C. & P. 
Perithecia gregarious, oblong or elliptical, sometimes slightly 
elongated and flexuous, covered by the epidermis which is ultimately 
ruptured in an irregular manner, blackish, disk pallid, at length 
exposed ; asci clavate; spores filiform; paraphyses slender, filiform, 
at first curved or circinate at the tips. 
Bark of Juniperus Virginiana. 
Diatryre Morowes C. & P. 
Rather small, erumpent, the disk at length obliterated by the 
crowded somewhat prominent hemispherical black ostiola; perithecia 
crowded, blackish; asci cylindrical ; spores uniseriate, oblong, uni- 
septate, colored, .0005—.0006' long, about .0002’ broad. 
Dead alders.
