Spots suborbicular, rusty brown, and finally whitening out in 
the centre, 1-3 mm. diam., or by confluence more; hyphae cespi- 
tose, short, abundant, 20-30 3 4, smoky hyaline, continuous, sub- 
undulate and obscurely toothed above; conidia clavate-cylin- 
drical, 30-60 3 y, 1—-3-septate.

Specc. on Bigelovia or Gutierrezia from Baldwin, Colo., differ 
from the type in the conidia varying from globose, 12-20 4, to ob- 
long or oblong-elliptical, 15-30X12-15 y, this latter form of 
conidia being most abundant. 
STIGMELLA CraTagcI E. & E. N. A. F., 3492; F. Col., 995. 
On leaves of Crataegus parvifolia, Newfeld, N. J., Aug.—Sept 
1895. 
Hypophyllous. Tufts punctiform, subeffused, black; prostrate 
hyphae hyaline, branched, bearing the globose, elliptical, or ob- 
long-elliptical dark olive-brown 1—3-septate and submuriform con- 
idia on short lateral pedicils. 
Outwardly resembles Hirudinmaria macrospora Ces. on the same 
host (see N. A. F., 373), but is really very different. 
IsaRIopsis MExIcANA E. & E. 
On dead shrubby stems, Monterey, Mexico, March, 1897. (Dr. 
B. F. G. Egeling.) 
Hyphae simple, brown, septate at intervals of about 35 y, 
loosely compacted into erect stipitiform tufts 300-400 y high and 
100 yz thick, thickly scattered over the stems and appearing like 
the cylindrical ostiola of some Diaporthe. The tips of the hyphae 
are paler above and recurved and swollen, developing at length 
into brown, multi-septate, 70-100 10-12 y# conidia. 
Differs from 7. gviseola Sacc. in its septate, longer hyphae and 
conidia ; from /. Grayiana EIl., in its coarser hyphae and multi- 
septate, much longer conidia and from /. Linderae E. & E., only 
in its habitat and much longer hyphae.
