44 Thirty-fourth Annual Report of the 



mountains. Aug. This fungus differs but slightly from Cribraria 

 tenclla. The persistent cup or basal part of the sporangium in that 

 species is entirely wanting in this, hence its resemblance to species of 

 Dictydium, This character appears to be constant, but should it fail 

 this fungus could scarcly be regarded as any thing more than a variety 

 of C. tenella. When this report was written this fungus was deemed 

 an unpublished species. Prof. Wm. Barbeck, then of Philadelphia, 

 had detected it, pointed out its distinctive character, and given it the 

 name Cribraria dictydioides, but before its publication it was distrib- 

 uted in Oooke and Kavenel's Fungi American! Exsiccati under the 

 name, which, owing to the delay in the publication of the report and 

 to avoid synonymy, I am permitted to here insert. 



Hendersonia Oydoniae, C. & E. Living leaves of pear, crab-apple 

 and apple. Catskill mountains and Sandlake. Aug. and Sept, 



Phyllosticta Sambuci, Desm. Living or languishing elder leaves. 

 Catskill mountains. Aug. 



Phyllosticta Grossularise, Sacc. Living leaves of red currant. Sand 

 lake. Sept. 



Phyllosticta Nesseae, n. sp. Spots suborbicular, scattered or some- 

 what confluent, pale-rufous; perithecia hypophyllous, numerous, very 

 minute; spores oblong, straight or slightly curved, colorless, .0003 in. 

 to .0004 in. long, about .0001 in. broad. Living leaves of swamp loose- 

 stripe, Nesma verticillata. South Ballston. Sept. 



Septoria Galeopsidis, West. Living leaves of hemp-nettle, Galeopsis 

 Tetrahit. Catskill mountains. Aug. 



Septoria Hydrocotyles, Desm. Living leaves of water pennywort, 

 Hydrocotyle Americana. Catskill mountains. Aug. 



Septoria Violae, West. Living leaves of violets. Catskill mountains. 

 Aug. 



Septoria Cucurbitacearum, Sacc. Living pumpkin leaves. Cat- 

 skill mountains. Aug. 



Septoria corylina, n. sp. Spots suborbicular, scattered, brown or 

 reddish-brown, with a darker margin; perithecia few, epiphyllous, 

 minute, blackish-brown, opening widely when moist; spores filiform, 

 curved, colorless, .0015 in. to .0018 in. long. Living leaves of hazel- 

 nut, Corylus rostrata. Millerton. June. The spots are usually one 

 and a half to three lines broad. They are darker on the lower than on 

 the upper surface. 



Septoria betulicola, n. sp. Spots small, often large by confluence, 

 angular, reddish-brown above, paler below ; perithecia hypophyllous, 

 verv minute, blackish; spores filiform, curved, colorless, .0012 in. to 

 .0018 in- long. Living leaves of birch, Betula lutea. Catskill moun- 

 tains. Aug. This is distinct from S. Betulm, both in the color. and 

 character of the spots and in the length of the spores. The perithecia 

 are so minute that they are scarcely distinguishable by the naked eye. 

 In variety marginalis the spots are marginal and confluent. 



Septoria microsperma, n. sp. (Plate 1, figs. 8-5.) Spots indefinite, 

 brown, sometimes confluent, perithecia hypophyllous, numerous, small, 

 irregular, brown, wrinkled when dry, rupturing irregularly ; spores 

 allantoid, colorless, .00035 in. to .0005 in. long. Fading leaves of birch,
