Heterosporiura Allii, E. & M. — On withered leaves 

 of Allium vinealc, Newfield, N. J., Aug. 1883. Hypbae erect, 

 subcontinuoua, nodulose, olive-brown, about 50 x 9 ft. Conidia 

 oblong, fuscous, minutely ecbinulate, 1-3-septate, 20— 30 x 

 9 {i. Differs from H. Ornithogali in its olivaceous color and 



smaller conidia. 



Septoria Pyrolae, E. & M.— On living leaves ofPyrola 



secunda, Red Rock, Lake Superior, June, Prof. J. Macoun, 

 no. 20. Appears at first in the form of little yellowish- 

 white pustules scattered over the lower surface of the leaf 

 but visible also above. Soon the little nerve-bounded areas 

 of the leaf, in which these pustules appear, turn brown bor- 

 dered by the limiting nervelets now lurned black, and in 

 place of the yellowish- white pustules appear little black 

 perithecia, opening below and tilled witl» tiliform, 25-— 35 x 

 ^li fi spores, obtuse at each end and only slightly curved. 



Septoria consimilis, E. & M. — On cultivated lettuce, 

 Geneva, N. Y., July (Arthur), Newfield, N. J. On brown, 

 dead, rather indefinitely limited spots Va— 1 cm in diameter. 

 Perithecia, brown, subglobose, innate, amphigenous, 90 

 100 H, scattered over the spots and visible on both sides 

 of tlie leaf. Spores fiHform, multinucleate, slightly curved, 

 ends mostly obtuse, 30 — 45 x 1—2 '/a f* hyaline. Differs 

 from S. Lactucae, Pass., in growing chiefly on spots, peri- 

 thecia also a little hirgi^r and spores a little longer but not 

 distinguishable by its spf)res alone. 



Phyllosticta Grordoniae, E. & M. — On living leaves 

 of G. lasiauthus, March. Spots dark brown, dry, occupying 

 the ends and sides of the leaves. Perithecia brown -black, 

 subglobose, innate, slightly erumpeut, amphigenous, 120 — 

 140 |M. Spores hyaline, oblong, nucleate, 12 x 3 ,«. 



Phyllosticta Perseae, E. & M. — On living leaves of 

 Persea Carolinensis, March. Spots brownish-gray, covering the 

 €nds and sides of the leaves. Perithecia brown -black, lenti- 

 cular, innate-orumpent, epiphyllous, 150 — 300 fi long, 60 

 80 /t broad. Spores oblong, hyaline, nucleate, 3—8 x 1 

 3 fi. This and the preceding species with P. terminalis 

 E. & M., and P. Myricae, Cke., were collected in the same 

 locality, and, from the similarity in their mode of growth 

 and the not very striking difference in their other characters, 

 they might be considered as varieties of tlie same thing; 

 this however, is a question that can not be definitely deter- 

 mined without knowing the ascigerous forms to which they 



all probably belong. 



Pestalozzia peregrina, E. &M.— On dead leavesof 



Pririus Austriaca, still hanging on branches cut off last year.
