Dec. 1903] 
New Species of Fungi 
223 
spots, sub-prominent, broadly perforated above, 100-125 n diam. 
Sporules narrow-clavate, 30-50 x 2-J /x , continuous, hyaline, grad¬ 
ually narrowed from the apex down. 
Calospora allantospora E. & E.—On dead limbs of 
Cornus alternifolia, and on Maple, Acer saccharinum, London, 
Canada, Oct. 1903 (Prof. J. Dearness, 2010). 
Perithecia scattered, buried in the bark and penetrating to 
the wood, depressed-globose, mm. diam., brown, not polished, 
walls carbonaceo-coriaceous; ostiolum conic- or short-cylin¬ 
drical, erumpent, rupturing the bark. Asci clavate, p. sp. 45-55 x 
7-9 . Paraphyses 50-90 long. Sporidia biseriate, cylindrical, 
curved, hyaline, obtuse, very faintly 3-septate, 15-20x2^-3 [i, not 
constricted at the septa which are so faint as to be easily over¬ 
looked. 
In the specimens on Maple the sporidia are smaller than in 
the specimens on Cornus. 
The ostiolum arises through a flat black disc visible through 
the ruptured epidermis, as in Clypeosphseria, and is easily broken 
off. 
Thyridium stilbostomum E. & E.—On dead Maple limb 
partly decorticated. London, Canada, Oct. 1903. (Dearness 
3001). 
Perithecia globose, ? J mm. diam., buried in the wood or 
bark, white inside. Ostiolum depressed-hemispherical, black and 
shining, pierced in the center with a minute opening. Asci cylin¬ 
drical, stipitate, paraphysate, p. sp. 75-80 x 8-10 ^ . Sporidia 
uniseriate, elliptical, brown, 6-7-septate and sparingly muriform, 
more or less constricted at the middle septum, 22-27 x 7-10 fj-. 
The perithecia are scattered or 3-5 in a genuine stroma, and 
those on the decorticated wood are smaller but all have the same 
sporidia. 
Diaporthe caryigena E. & E.—On dead Hickory limbs, 
London. Canada, Oct. 1903. (Dearness, 2863). 
Perithecia lying 3-6 together in the inner bark but not pene¬ 
trating the wood, globose, small (J mm.), each group surrounded 
by a black, circumscribing line which penetrates the wood for 
■J-i mm. and when the limb is split appears like a section of a 
shallow cup, the included wood being of a much lighter color. 
Ostiola fasciculate, raising the epidermis into pustules and finally 
piercing but not laciniately rupturing it or rising above it, tips 
of ostiola smooth, papilliform. Asci subcylindrical, p. sp., about 
60 x 10 u. Sporidia mostly uniseriate, elliptical, uniseptate, ends 
rounded and obtuse, constricted, each cell with a large transparent 
nucleus, 9-13 x 3J-4J v. 
D. eusticha E. & E., D. woolworthii Pk., D. apocrypta C. & 
E. have no circumscribing line and D. corymbosa C. & E. to 
which it comes nearest, has larger sporidia.
