at first, linally brown and uniseptate, and more or less constricted at 

 the septum.

The mycelium forms small (2-4 mm. long), oblong or elliptical, 

 black patches consisting of a thick growth of erect, simple, septate, 

 subnodulose, sterile hyphse, nearly hyaline at first, but soon opake, 

 130-175 x 6-9 fji, and pale yellowish, prostrate hypha?, producing 

 f'usoid-cylindrical or subfalcate, nucleate conidia 40-60 x 3 p.. Nest- 

 ling among the sterile bvphas are black, meinbranaceous, subovate 



t/ i 



perithecia J-J mm. diam.. with a very large opening above. Asci 

 clavate-cylindrical, 75x15 j, with imperfectly developed paraphyseg. 

 Sporidia 8 in an ascus, oblong-cylindrical, yellowish (nearly hyaline), 

 slightly curved, 3-4-nucleate, becoming uniseptate, 18-20x4-5 //. 

 Some sporidia were seen imperfectly 3-septate, but one septum seems 

 to 1)6 the normal state. This is remarkable for the large apical open- 

 ing more like a half-grown Genangium than like an ostiolum.

Mycelium brown-black, branching, septate, epiphyllous. Co- 

 nidia brown, ovate, uniseptate, 10-1 2 x 6 JUL. Macroconidia brown, ped- 

 icellate, submuriform, 3-septate, 35x15 fi. Perithecia brown-black, 

 subglobose, 50-100 /* diam. Asci oblong-ovate, sessile, 8-spored, 

 35-40 x 11-16 t a. Sporidia hyaline, subcymbiform, uniseptate, 2-seri-

Asterina conglobata, B. & C. Grev. IV, p. 9. 



Perithecia hypophyllous, globose, about 50 , astomous, coarsely 

 cellular, membranaceous, in compact, subcontinent groups of 46 on a 

 subcrustaceous mycelium. Asci obovate, 20-25 x 10 fjt, without par- 

 aphyses. Sporidia oblong, uniseptate, hyaline, 6-8 x 2-2J /2.
