comparison with a cotype, and questions that this species has the 

 pycnidial characters of a good Phyllosticta. 



Pleospora herbarum (Pers.) Rabh. 

 On dead stems of Triglochin mariti'mum L. Bergen 

 swamp, Genesee county. H. D. House, June 2, 19 16. 



Pyrenopeziza compressula Rehm. 

 On dead stems of Helianthus lacinatus L. Oneida 

 H. D. House, June 5, 1916. (Determined by Dearness.) 



Puccinia angustata Peck 



Manorville, N. Y., onScirpus cyperinus (L,) Kunth. 

 H. D. House, June 20, 1916. (Determined by Arthur.) The other 

 host species for this rust in New York are Scirpus atrocinc- 

 tus Fernald; S. atrovirens Muhl. ; S. sylvaticus L. 



The type of this rust is supposed to occur upon S. sylvaticus 

 collected near "West Albany," by Doctor Peck, but since that sedge 

 probably does not occur in that region the identity of the host 

 remains in doubt. The aecial stage (Aecidium lycopi Ger.) 

 is frequent upon various species of Lycopus. 



Puccinia ellisiana Thum. 

 The aecial stage was collected at Manorville, N. Y., on leaves of 

 Viola lanceolata L., June 20, 1916. It also occurs upon 

 leaves of Viola blanda and V. affinis (Aecidium 

 mariae-wilsoni Peck). The telial stage appears to be rather 

 common upon Andropogon scoparius Michx. and A. 

 furcatus Muhl. at Karner, Albany county, and on Long Island. 



Puccinia extensicola Plowr. 

 The following species are represented among the hosts for the 

 aecial stage in the state herbarium: Aster cordifolius, 

 A. macrophyllus, A. novae-angliae, A. longi- 

 folius, A. puniceus, Erigeron pulchellus, E. 

 philadelphicus, E. annuus, E. ramosus, Leptilon 

 canadense, Euthamia graminifolia, Solidago 

 canadensis, S. 1 a t i f o 1 i a, S. o d o r a, S. lanceolata, 

 S. j u n c e a, S. r u g o s a, S. thrysoidea and S. u 1 i g i-
