48 ROCHESTER ACADEMY OF SCIENCE. [March 24, 



Among the Discomycetes we have a wide range of forms from our 

 largest morel — Morchella esculenta var conica — to the microscopic 

 Pezizas. The genera represented are Peziza, Morchella, Propolis, 

 Stictis, Patellaria, Dermatea, Tapesia, Encoelia, Helotium y Ascophanus 

 and Ascobolus. Our earliest species is Peziza coccinea, J acq., which 

 occurs at the same time as the spring beauty {Claytonia) and the Hepatica. 

 Some of our species are quite rare, as for instance Tapesia Rosa, (Pers.), 

 found on dead stems of wild rose. Mr. Ellis, to whom specimens 

 were sent, says that he had never before had Tapesia Rosa; from this 

 country. We have also, recently, found a Dermatea growing on twigs 

 of Lindera benzoin, which is apparently near D. Vlburnicola Ell. in 

 Torr. Bulletin {D. purpurea, Ell. olim). 



The following list contains the new species and varieties which we 

 have added to the mycologic flora of Western New York. 



1. Fenestella amorpha, E. and E. 



Jour. Mycol, vol. 4, page 58, vol. 5, page 79. 



On fallen branches of hickory (Carya) in the spring. We have 

 attempted to trace the development of the sporidia of this fungus in 

 an article prepared for Jour. Mycol, vol. 6, on the " Development of 

 Some Fenestrate Sporidia." See also plates I and II, Jour. Mycol. vol. 

 6, for figures of the Fenestella. 



2. Didymosphaeria accedens, Sacc, //. sp., (Plate 4, fig. 12). 



" Peritheciis gregariis, tectis, %~Yi m. m. lat., ostiolo laeve 

 papillato erumpento, nucleo primo albo. Ascis tereti-clavatis 120x10 /i., 

 paraphysibus obsoletis. Sporidiis senis octonisve, ellipsoideis, utrinque 

 rotundatis, 1 septatis, leviter constrictis, 20-22x9-11 //., fuligineis 

 monostichis. Affin. D. Rhamni et D. incarcerato ostiolo ascisque 

 diversa." Saccardo in litt. Hab. on dead branches of some tree (Ash ?). 



April and May, 1889, Lyndonville, N. Y, 



3. Anthostomella eructans, E. and E., n. sp., (Plate 4, figs. 7-8). 

 Perithecia gregarious, globose, /^-^ m. m. diam., with thick 



coriaceous walls, buried in the wood, abruptly contracted above into a 

 short neck with an obtuse-conical erumpent ostiolum. Asci cylindrical, 

 75-80x7 jx. (p. sp.) with abundant paraphyses. Sporidia uniseriate, 

 brown, continuous, rather acutely elliptical, 10-15x5-7 //. (mostly 

 12x5 fi.). The surface of the wood is uniformly blackened and the 

 sporidia when mature are discharged as in Massaria. 



On decorticated (maple ?) limb. 



Lyndonville, N. Y., May, 1889. Fairman, No. 42.
