166 PROCEEDINGS OF THE ACADEMY OF [1893. 



Perithecia gregarious, erumpent-superficial, thin, black, J— \ mm. 

 diam., closed, globose and smooth at first, soon broadly open above 

 and cup-shaped, with the margin substriate and more or less distinctly 

 fringed with short, brown hairs. Sporules navicular, continuous, 

 olivaceous, 5-6 x 2|/>-, ends acute, borne on simple, stout, olivaceous 

 basidia about 12 x 2|//.. 



Excipulina hicksiana E. & E. 



On bleached, decorticated wood, Michigan. (G. H. Hicks.) 

 Perithecia, scattered, globose or oblong and hysteriiform, J-f mm. 

 in the longer diameter, thin, membranaceous, obsolete below, darker 

 and more coarsely granular toward the margin, at first closed, soon 

 opening with a longitudinal dehiscence like a Hysterimn, base 

 adnate to the wood, hymenium, pale. Sporules oblong-cylindrical, 

 hyaline, obtuse, 2-3-septate, 8-15 x 3-4//, straight or slightly 

 curved; texture loosely cellular, thin, not fibrous. 



Catinula saligna E. & E. 



On dead limbs of Salix, London, Canada. Feb., 1890. (Dear- 

 mess, No. 1,420.) 



Perithecia scattered, erumpent, short cylindrical or obconical, sub- 

 stipitate, about 1 mm. high, broadly perforated or open at the apex, 

 black and subshining. Sporules oblong-cylindrical, hyaline, con- 

 tinuous, 15-20 x 6— 7/-/-, on basidia 15-20 x 3/i. 



This differs from 0. turgida Desm. only in its more elongated 

 perithecia and rather narrower sporules. A form occurs on Car- 

 pinus (Dearness, No. 1,565) that cannot be distinguished from C. 

 turgida, and it may be as well to consider our C. saligna as only a 

 robust form of that species. 



Hainesia borealis E. & E. 



Ell. & Evrht. N. A. F., 2,785. 



On leaves of Galium boreale, British Columbia. July, 1889. 

 (J. Macoun.) 



Acervuli hypophyllous, scattered, convex-discoid, 175-200// 

 diam., flesh-colored becoming darker when dry, subcuticular at first 

 but soon erumpent-prominent. Conidia allantoid, hyaline, slightly 

 curved, 5-Q x I/a on simple, slender basidia 12-15 x 1-1 £/i. 



The parts of the leaf occupied by the fungus soon become pale 

 brown and dead. Hainesia rubi (West.) has been sent from 

 Ontario, Canada, by Mr. Dearness.
