Septoria Dearnessii, n. s. On Archangelica atropurpurea , Lon¬ 
don, Canada, August, 1889. Mr. J. Dearness, 552. Spots amphi- 
genous, dark brown, irregular, angular, 1-5 millimeters in diameter. 
Perithecia innate, minute, slightly prominent, very obscure. Sporules 
issuing in white cirrlii, 15-22 by 1 4//, without nuclei or septa-, nearly 
straight. Approaches Cylindrosporium on account of the imperfectly 
developed perithecia. 
Septohia divaricata, n. s. On living leaves of Phlox divaricata > 
Lyndonville, N. Y., May, 1889. Dr. 0. E. Fairman, 44. This is the 
Septoria phlogis, S. & S. f in Journ. Mycol., III j p. 85. The Lyndonville 
specimens agree exacts with the Iowa specimens so that there is 
reason to*think this is not an immature state of S. phlogis, S. & S., but 
a different thing. In fact it differs throughout from the description of 
that species. The spots are not white, only whitish, and the sporules 
instead of being 40-C0 by 1-2// and 1-3-septate are 15-35 by lju , 
mostly 20-25/1 long, nearly straight instead of flexuous, and very faintly 
nucleolate but not septate. 
Septoria Fairmani, n. s. On living leaves of Hollyhock* (Althcea 
rosea), Lyndonville, N. Y., June, 1889. Dr. C. E. Fairman, 77. 
Spots amphigeuous, scattered, subangular, 3-4 millimeters in diameter, 
dark brown and limited in part by the veinlets, border narrow and 
dark. Perithecia epiphyllous, rather numerous, scattered quite evenly 
over the spots, black, 100-112//, subprominent. Sporules filiform, 
slightly curved, nucleate, 30-45 by l£-2//, hyaline. Whether 8. althcece , 
Thiim., is different from this it is impossible to tell, as the specimen in 
his Austrian Fungi, 955, is a Ccrcospora. He says of this (F. Aust., 
955) “perithecia arranged in a circle on dry pale brown spots,” which 
applies very well to his specimen. Apparently De Thiimen mistook 
the tuffs of Cercospora-f or perithecia. In Dr. Fairman’s specimen the 
spots are dark brown. 8. lachastreana , Sacc. & Let. has the sporules 
3-septate, and the perithecia are smaller and on minute whitened spots. 
On the same leaves is a Phyllosticta with oblong 3-4 by 1J-2// sporules, 
on white deciduous spots of about the same size as those producing the 
Septoria. The Phyllosticta agrees withP. altliceina , Sacc., only the spor¬ 
ules are smaller. 
Septoria cryptomjnije, Ell. & Fan.? J. M., Ill, p. 50. Speci¬ 
mens collected in Delaware by Mr. Commons (910) enable us to 
add the following notes: Spots white, becoming brown, angular, lim¬ 
ited by the veinlets. Perithecia epiphyllous, erumpent, black, de¬ 
pressed-globose, 100-120//, scarcely visible below. Sporules filiform, 
yellowish, attenuated towards each end, faintly nucleolate, slightly 
curved 20-30 by 1J-1J//. The leaf turns yellow around the spots. 
Perithecia not abundant. This is closely allied to S. ccgopodina , Sacc., 
which, however, has smaller perithecia. It is certainly very different 
from the specimen labeled Septoria wgopodina, Sacc. in Fungi Gallic!, 
1317. From S. sanicuUc , F. & F. (J. M., IV, 44) it differs in its huger 
spots, perithecia, and sporules.
