26 Thirty-thikd Annual Eeport of the 



Cytispora minuta, Tlium. Dead branches of ash, Fraxinus Ameri- 

 cana. West Troy. May. 



Gloeosporium Trifolii, n. sp. Spots suborbicular often concentric- 

 ally zoned, brown ; spores oblong or cylindrical, obtuse, simple, color- 

 less, .0006 in. to .0009 in. long, .00016 in. to .00025 in. broad 

 Living leaves of red clover, Trifolium pratense. Albany. July. 



Gloeosporium salicinum, n. sp. Spots large, irregular, indefinite, 

 arid, pale; spores elongated, subfusiform, curved or flexuous, ob- 

 scurely triseptate, each cell usually containing two nuclei, colorless, 

 .0016 in. to .002 in. long. Living leaves of willow, Salix sericea. 

 Sandlake. Aug. Usually one end of the spore is more acute than 

 the other. 



Gloeosporium Hepaticae, n. sp. Spots large, irregular, often discolor- 

 ing the whole leaf, blackish-brown ; pustules minute, scattered, 

 epiphyllous, the thick tendrils pinkish when dry ; spores oblong or 

 cylindrical, colorless, obtuse at each end, straight or slightly curved, 

 .0006 in. to .001 in. long, .00025 in. to .0003 in. broad, usually with 

 two to four nuclei. Living leaves of liverwort, Hepatica acutiloba. Hel- 

 derberg mountains. July. This species appears to be very destruct- 

 ive to the leaves it attacks. The discoloration apparently spreads 

 rapidly and finally involves the whole leaf. 



Gloeosporium Laportae, n. sp. Spots orbicular, yellowish-green with a 

 dark-margined arid center ; spores simple, globose or elliptical, color- 

 less, .00016 in. to .00025 in. long, uninucleate or binucleate, forming 

 a pallid globule on the upper surface of the spot. Living leaves 

 of wood nettle, Laportea Canadensis. Charlton. July. 



•Coryneum pustulatum, n. sp. (Plate 1, figs. 1-3.) Pustuliform, 

 seated on the inner bark, covered by the elevated epidermis which is 

 at length pierced or slightly ruptured ; spores long, subclavate or sub- 

 fusiform, colored, five to seven septate, often strongly curved, .0025 in. 

 to .003 in. long, about .0005 in. broad; sporophores short. Dead 

 branches of oak or chestnut. Sandlake. May. The spores some- 

 times ooze out and stain the matrix black. This and its pustulate 

 form give the fungus the appearance of a Stilbospora, though the struc- 

 ture indicates that it is a Coryneum. 



Pestalozzia Guepini Desm. Living leaves of Camellia in conserva- 

 tories. Buffalo. Clinton. 



Asterosporium betulinum, n. sp. (Plate 1, figs. 4-5.) Pustulate, 

 erumpent, with a black orbicular disk, the stroma filamentous ; spores 

 three or four-radiate, slightly colored, the rays oblong-ovate or elon- 

 Igate-conical, subacuminate, three to five-septate, .0008 in. to .0015 in. 

 ong, .00035 in. to .00048 in. broad in the widest parts, slightly narrowed 

 at the base, the cells often uninucleate, the terminal one paler. Dead 

 branches of birch, Betula lutea. Quaker Street. June. Externally 

 this closely resembles A. Hoffmanni, but in European specimens of 

 that species the rays are triangular-ovate and widest at the base where 

 they are .00065 in. broad. In our plant they are paler, narrower, 

 more elongated and abruptly narrowed at the base. I have been un- 

 able to detect a perithecium else I should refer our plant to Prostlie- 

 mium betulinum Kze. 



Melanconium cerasinum, n. sp. Stroma distinct, thin, white ; 

 spores very unequal, globose, ovate, elliptical or oblong, .00065 in. to .001
