Spores are shown in Fig. (Sp.). It was found that the spores 
readily germinated in water and still more freely in a decoction 
made from Lactuca stems, the germ tube appearing within 24 
hours. A few germinated spores are shown in the Fig. at g. 
The diagnosis of the species may be given as follows: 
N^emosph^era lactucicola Kellerm. n. sp. — Pycnidia 
beaked, clustered but distinct, occupying large areas, deeply 
seated, at maturity barely perforating the epidermis, black, brit¬ 
tle, globular to pyriform, 150-250/* in diameter, ending in a 
rather broad beak of varying length but usually about one-half 
that of the pycnidium; spores brown with an olivaceous tint, 
broadly oval or oblong, not septate, 18-24x7-12/*. 
On old stems of Lactuca virosa, Columbus, Ohio. April 
15, 1904. (Kellerman, 4208.)

Uncinula parvula. — When examining herbarium speci¬ 
mens of various species of Uncinula recently, it was found that 
my copy of “No. 149/ Uncinula polychaetae B. & C., A. B. Sey¬ 
mour & F. S. Earle, on Celtic occidentalis, Starkville, Miss.” 
contained both Uncinula polychaeta and Uncinula parvula. These 
were mostly on separate leaves but in one case both species grew 
intermixed 011 the same leaf. Of S. M. Tracy’s “Plants of the 
Gulf States, No. 8273, Uncinula polychaeta B. & C., on Celtis 
occidentals, Weatherford, Texas, Oct. 20, 1902," the copy belong¬ 
ing to the Carnegie Museum, Pittsburg, [Acc. No. 2263] is not 
as named, but exclusively Uncinula parvula Cke. & Peck. 
Mycological Flora of Cedar Point. — This locality is a 
sand spit opposite Sandusky Bay, on the Southern shore of Lake 
Erie. Its length is about six or seven miles, mostly only 500 
to 2,000 feet in width except the upper (outermost) portion which 
for the distance of nearly a mile is from 3,000 to 4,000 feet 
across. I11 this widened apex are a couple of swales and most of 
the season ponds remain of considerable area. The sandy soil 
supports no sod generally, but a herbaceous flora of perhaps 
300 species grows with some luxuriance. The bog and aquatic 
plants are abundant on the Bay side of the spit where the out¬ 
line is very irregular, one or two of the recesses or bayous occu¬ 
pying considerable area. The trees are rather abundant through¬ 
out— the Cottonwood, Willows and Oaks (especially the black, 
and shingle Oaks) are abundant and many other species occur in 
lesser quantity. The mycologic flora is more abundant than 
would be expected perhaps. The following species have been 
collected.
