Peziza Earliana. — Erunipent, scattered, liver-color; darker 
when dry, closely surrounded by the epidermis, hemispheric and 
nearly closed at first, at length expanding so as to show the pallid 
disk; margin suberoded, minute (.12-17"""-); ^sci sessile, oblong, 50- 
55x12//; paraphyses stout, and, wdien mature, distinctly and abruptly 
swollen at the tips ; sporidia crowded, oblong-cylindrical, obtuse at 
each end, 3-4-nucleate, hyaline, 15-.18X 2.5-3/^. 
Differs from P. Dehnii, Rab., in its smaller size, scattered mode 
of growth, broader asci, larger sporidia and club-shaped paraphyses. 
On the under side of dead leaves of Fragaria. Anna, 111., May. 
1883. F. S. Earle. 
Nectria Canadensis. — Perithecia c^espitose, ovate, .33"""* ^^p^^ 
by about .5"^"^- high, densely tuberculose-granulose, dull red ; ostiola 
broad, obtuse, not prominent, but distinctly stellate cleft and slightly 
collapsing when dry ; asci and paraphyses evanescent, the former 
about 75-80x10-12// (spore-bearing part) ; sporidia irregularly 
crowded, hyaline, oblong, 3-septate, slightly curved, ends obtu-se, 
18-2 1x7-9//* 
The conidial stage is a Tnbercidaria, .5-2"'"'* high, with an orange- 
colored head bearing oblong, 5-7x1.5// conidia and brick-red stem 
bursting out through cracks in the bark in continuous series two or 
three inclies or more in extent. From the basal portion of this 
Tubercularia the perithecia arise, and finally entirely surround ana 
overtop the orange heads of conidia, which are either entirely hid- 
den or remain partly visible in the midst of the dense clusters 01 
perithecia.

Boselltnia Macouniana. — Gregarious, superficial, ovate, ,^2>l 
lUlll. 
in diameter, covered, with the exception of the prominent ostiohim, 
with a coat of short, light purplish tomentum; asci long and narrow 
(loo// and over); sporidia uniseriate, overlapping, 19-22 by about 6/<, 
2-nucleate, brown, oblong or subnavicular. 
On rotten wood. Ottawa, Canada, Oct., 1883. Macoun (No. 
253.) From other localities I. have received specimens of what 
appears to be the same, only with the perithecia denuded and black 
(old) and much resembling old specimens of Sp/iccHa siibicidata, 
Schw., which, in the absence of the yellow evanescent subiculuni, 
may be distinguished from this by its smaller (10-13/^ long) sporidia. 
Nummulakia pezizoides. — Stroma carbonaceous, erumpent, 
superficial, depressed-obconic, black outside and rufous brown withm, 
about i'^"'- broad and .5*^'"- thick, with a narrow sublobate margin, 
disk thickly studded with the strongly prominent, papillate ostio^a, 
perithecia flask-shaped, or subangular by compression, about i 
high; sporidia narrow-elliptical, a little bulging on one side, brown, 
i-2-nucleate, 11-13x4-5/*. , -. q\
