gated, often curved, lying in various directions on the matrix, ends 

 acute ; lips narrow, slightly swollen, edges somewhat remote. Asci 

 oblong, 8-spored,subsessile, 60-75x20-22 /i. Paraphyses branched 

 above. Sporidia inordinate, subelliptical, hyaline, muriform, 20-30 x 



12-15 li. 



On bark of Carya alba, New Paltz Landing, N. Y. (Gerard), on 

 dry, exposed wood, Ohio (Morgan), on cast-off bark of Acer and of 

 Pyrus Mains, and on decorticated oak limbs, Newfield, N. J; com- 

 mon, but not abundant.

Perithecia erumpent-supei-ficial, lying in the direction of the fibers 

 of the wood, frequently parallel, linear, narrow, rounded at each end, 

 1-2 mm. long, straight, faintly striate ; lips acute, nearly closed. Asci 

 cylindric-clavate, paraphysate, 8-spored, subsessile, 57-60 x 12 /.i. Spo- 

 ridia biseriate, clavate-oblong, 3-septate, with one or two of the broader 

 cells often divided by a longitudinal septum, 12-15 (exceptionally 20) 

 X 5-6 fi, hyaline. 



On dry, hard wood of deciduous trees. New York State (Peck & 

 Fairman), Louisiana (Langlois), on old, dry oak wood. New Jersey 

 (Ellis). 



The above diagnosis is from the original specimens of Hysterium 

 gloniopsis, determined by Gerard. The specc. of H. hyalinum, 

 C. & P., determined by Cooke, do not differ appreciably. .In the 

 diagnosis of H. hyalinum, in Disc. U. S. the sporidia are said to be 

 26-28 X 6-8 11, but we can only make them as stated above. In a 

 spec, of Hysterium hyalosporum, Ger., from Gerard, the sporidia, 

 when mature, become brown, though they remain for a long time 

 hyaline, but in all other respects the spec, agrees so well with the 

 characters given above that it cannot well be separated. In the 

 original description o^ Hysterium hyalinum, 0. & P., nothing is said 

 of any longitudinal septa in the sporidia, but in the mature sporidia 

 they are always present.
