Dearness: New Species of Fungi 
99 
On the preceding season’s basal leaves of Solidago juncea Ait., 
near Byron, Ontario, /. Dearness 3088, collected in 1904 and ob- 
served annually since until date. 
In autumn the infected leaves are extensively discolored, red- 
brown to blackish-brown, usually the entire right or left half, 
seldom both sides of the midrib. Black, subglobose “ sclerotia,” 
mostly about 140 in depth and 240 /t in breadth, are thickly scat- 
tered, 3 or 4 to the sq. mm., over most of the darkly discolored 
area, prominent on the upper side but visible beneath, containing 
a white mass of coarse parenchymatic cells about 7/4. 
Specimens wintered out of doors began to show asci by the 
middle of April. Sporidia issued freely in sections in water in 
the latter half of May. This will be distributed in Fungi 
Columbiani. 
4. Trichosphaeria breviseta sp. nov. 
Perithecia black, crowded, appearing to the naked eye as a con- 
tinuous stratum, 3 but not quite 4 to the lineal mm., globose- 
conic; bristles 15 to 20 ju, usually limited to the basal half of the 
perithecia. Asci linear, 50-75 n, shorter than the abundant para- 
physes. Sporidia uniseriate, nucleate at each end, hyaline, 6-7 X 
3 - 3-5 
On rotten coniferous wood, Victoria, B. C., April, 1915, John 
Macoun. 
5. Diaporthe Euonymi sp. nov. 
(In Euporthe). Stroma widely effused, sometimes surround- 
ing the stem or in small patches containing one or a few contig- 
uous perithecia, whitening the substance of the bark and causing 
it to adhere firmly to the wood which is marked by a black circum- 
scribing line. Perithecia single or in small groups, 2 to 4, not 
circinating, partly sunk in the wood, globose, 270-500/* in di- 
ameter; the cylindric to conic ostiola 100 /* thick, erumpent 
through the epidermis, 100-130/*, in richly fertile parts closely 
ranked and appearing to the naked eye as black parallel lines. 
Asci cylindrical to fusoid, sessile, 8-spored, paraphysate, 60-75 X 
11-15/*. Sporidia obliquely uniseriate or sub-biseriate, oblong- 
elliptic, not constricted, septum distinct, 12-15 X 6-7/*. 
On dead stems of Euonymus atropurpureus Jacq., Delaware, 
Ontario, June, 1913, /. H. Bowman.
