Asci clavate. Sporidia biseriate", shortly fusiform, hyaline, biseptate. 

 No measurements given. 



On Lycopodium, New Jersey. 



CERIOSPORA, Niessl. (Plate 32) 



Not. Pyr. p. 9. 



Perithecia scattered, sunk in the matrix, with the ostiolum erum- 

 pent, and the perithecia themselves finally suberumpent or exposed. 

 Asci 8-spored. Sporidia fusoid, 1-3-septate, yellow or yellowish- 

 brown, with a hyaline, mucronate appendage at each end. Paraphyses 

 evanescent. 



In the original diagnosis of the genus, only the ostiola are erum- 

 pent, but in both the species here described the perithecia themselves 

 are finally erum pent-superficial. Dr. Winter includes this in Fam. 

 Gnomoniece, but it seems to us more closely allied to Pleosporece. 



C. Montaniensis, (E. & E.) 



Lophiostoma Montaniensis, E. & E. Journ. Mycol. IV, p. 64. 



Perithecia scattered or oftener seriate in longitudinal cracks in 

 the bark, erumpent-superficial, depressed-globose, J-f mm. diam., 

 smooth, with a small, tubercular-papilliform ostiolum pierced with a 

 slightly elongated opening. Asci cylindrical, p. sp. 80-90x7-8 u, 

 with filiform paraphyses. Sporidia uniseriate, oblong-elliptical, 3-sep- 

 tate, the two middle cells brown, the terminal cells hyaline and acute, 

 prolonged into a filiform appendage 6-8 p. long. Colored part of the 

 sporidia 12-14x6-7 y.. The sporidia are exactly like those of a 

 single-crested Pestalozzia, but they are produced in asci. 



On dead stems of Clematis ligusticifolia, Montana (Anderson). 



A more careful examination shows that this can not be a Lophios- 

 toma. The description in Journ. Mycol. is faulty, "cm." should be 

 "mm./ 7 and the measurements of the sporidia are omitted. 



C. Alabamiensis, E. & E. (in Herb.) 



Perithecia scattered, tubercular-hemispherical, but covered by 

 the epidermis, obtuse and perforated above, brown, J-| mm. diam.. 

 base broadly adnate and slightly sunk. Asci cylindrical, short-stipi- 

 tate 90-100 x 6-8 /i, paraphysate. Sporidia uniseriate, ends over- 

 lapping, fusoid-oblong, yellowish-hyaline, subinequilateral, 12-15x4- 

 5 //, with a straight, hyaline bristle or awn 10-15 ju long at each end, 

 with a large nucleus at first, becoming uniseptate. 



On dead herbaceous stems, Alabama (Atkinson).
