NEW OR RARE 



PYRENOMYCETEtE 

 NEW YORK. 



FROM WESTERN 





Charles E. Fairman. 



Presented by title February 12, 1906. 



The species here enumerated were collected at Lyndonville, N, Y. , 

 unless other locality is given. The numbers run on consecutively 

 from the list of Pyrenomyceteae of Orleans County, printed as pages 

 165- 191 of this volume, to which this paper is supplementary.* 



Among the Ophioboli are some species distinguished by having 

 curved sporidia. The curves may occur at any point in the sporidium, 

 from one-third to one-half its length. Some are straight while in the 

 ascus, becoming curved only when free. Some of the species with 

 curved sporidia have, also, one or more of the joints swollen, at a' 

 point varying with the species. Most of the species of this genus 

 occur upon dead stems, and but rarely upon leaves. Hence the fol- 

 lowing species is deemed worthy of mention, inasmuch as it combines 

 the features of curved sporidia, swollen joints, and foliicolous habitat. 



355. Ophiobolus sceliscophorus Fairman, n. sp. 



Perithecia minute, black, seated upon dead arid spots on the 

 leaves ; asci clavate-cylindrical, mostly bent, but occasionally straight, 

 the curvature corresponding to a similar bend in the sporidia, 90-100 x 

 10 fJi; paraphyses not seen; sporidia filiform, curved, lo-ii septate, 

 the joint at a distance of 30 u from the end, (one-third the length), 

 slightly swollen, hyaline, about the length of the ascus, 90 x 2 j^ to 3 /i.

On leaves of Phlox drtimondii, in garden, Lyndonville, N. Y. , 

 1905. Etym. from Gr. skeliskos, a little leg, and pherein, to bear. 



*In reference to number 285 of the first list, Otthia morbosa (Schw.) E. & E., Professor P. A. 

 Saccardo writes from Padova Nov. 11, 1905. "J'observe que vous referez d'apres votre illustre 

 am. Ellis le Plowrightia morbosa au genr. Otthia, mais si vous pensez qu'il est un vrai parasite 

 hypertrophisant vous resterez convencu qu'il est un type tres-distinct." 



Number 331, Lophiostoma pruni E. & E., was found on decorticated branches of Salix on the 

 beach of Lake Ontario- at Shadigee, Orleans Co., Nov. 18, 1905. Det. Rehm. This is a new 

 habitat for this species.
