14. Septoria malvicola, E. and M. 
Jour. Mycol.,, vol. 3, page 65. 
On leaves of Wa/va rotundifolia. 
Prof. Peck has referred our specimens to Septoria heterochroa, 
Desm. 
15. Diplodia spirzicola, E. and E., x. sf., (cz Wt.) (Plate 4, 
fig. 13). Spores smaller than either of the described species on Spiraea, 
measuring 8-10x3-4 uw. 
D. Spiraeae has spores 14-20x8 w., and D. Spiraeina, Sacc., has 
spores 20-22x10 uw. (Mr. Ellis now thinks this species may come 
under D. Spiracae.) 
On dead stems of cultivated Spiraea hyperictfolia, June, 1889. 
16. Diplodia maura, C. and E., x. var. 
Var. Americana Ell, in litt. 
On dead limbs of mountain ash, P. Americana. 
17. Morthiera Thuemenii, Cooke, var spherocysta, Peck, 
(tx litt). 
Jour. Mycol, vol. 5, page 79. 
On Crategus at North Ridgeway on the County line road between 
Orleans and Niagara counties. 
18. Haplosporella Ailanthi, E. and E. (Plate 3, fig. 5). 
Jour. Mycol. vol. 5, page 147. 
On dead Adlanthus glandulosus. 
19. Sphzropsis Lappe, E. and E., x. sp. 
Perithecia scattered, subglobose, ¥%3 m. m. in diameter, at first 
covered by the cuticle, soonerumpent superficial. Sporules elliptical, 
brown, with a single large nucleus, 15—20x8-10 wu. 
On dead stems of burdock (Zappa major), May, 1889. 
20. Sporonema pallidum, E. and E. 
Jour. Mycol, vol. 5, page 153. 
On decorticated maple, Ridgeway, N. Y., May, 1889. 
21. Sporidesmium toruloides, E. and E., x. sf., (Plate 4, fig. 3). 
Forming small(r m.m_) gregarious, cushion-like, black tufts, some- 
times subefused. Conidia various, mostly toruloid, forming simple or 
branched chains of cells, 12-25X5—7 ». Most of the component cells 
divided by a longitudinal septum, or also subglobose 5—-7x5-7 ux. 
This is closely allied to Septonema toruloideum, C. and E., and to “Conto- 
thectum’” toruloideum, B. and C., but differs from both of these in its 
longitudinally divided (muriform) cells, which are also slightly muri- 
cate-roughened. 
On dead wood and bark of Cornus, Lyndonville, June, 1889.
