This has the outward appearance of the specc. on white oak bark, 

 mentioned in N. A. Pyr. , p. 178, but the asci and sporidia are 

 smaller, and the latter are brown. Notwithstanding these discrep- 

 ancies, the Newfield specc. are no doubt referable to Sphceria papilla 

 Schw. 



Trematosphseria mastoidea (Fr. ). 



Starback, 1. c, gives as syn. of this species: Sphceria albicans 

 Schw., Syn. Car., 176, and Sphceria obtecta, Schw., Syn. Car., 206. 



The spec, in Herb. Schw. is entirely without fruit. 



Sphceria denudans Schw., Syn. N. Am., 1,625, is appai'ently a 

 Trematosphceria, but the spec, in Herb. Schw. is old, and the peri- 

 thecia mostly broken down. A few free spores were seen, oblong, 

 dark brown, 3- septate, 20-22 x 7-8//. 



Trematosphseria applanata (Fr. ). 



Sphceria applanata Fr., S. M., II, p. 463 (in part at least). 

 Sphceria applanata Oudern., Anwinst. Myc. Neder., 1875-1876, p. 11. 

 Sphceria Aspergrenii Fr., in Herb. Schw. 

 Trematosphceria applanata Sacc, Syll., II, p. 120. 



From the spec, in Herb. Schw. the following diagnosis has been 

 made: — 



Perithecia scattered, erumpent-superficial, depressed-hemispherical, 

 170-200;/. diam., becoming more or less collapsed above, with a 

 papilliform ostiolum. Asci oblong-cylindrical, short- sti pi tate, p. 

 sp. 75-80 x 18-22//, paraphysate, 8-spored. Sporidia obliquely 

 uniseriate, or biseriate, clavate- oblong, 4-5- (mostly 4-) septate, 

 and finally constricted at the septa, 24-30 x 7-9//, surrounded with 

 a hyaline envelope. 



This is certainly different from Trematosphceria, applanata (Fr.), 

 Fckl. Symbolse Myc, p. 162, N. Am. Pyr., p. 206, which is an 

 Amphisphceria, having uniseptate sporidia broader below, while this 

 has 4-5-septate sporidia narrower below. Apparently it is the same 

 as that described by Oudemans, 1. c, though he says nothing of the 

 hyaline envelope, which is very distinct in the Schweinitzian spec. 



Trematosphaeria astroidea (Fr. )? 



Sphceria astroidea Fr. ? (in Herb. Schw.). 



Perithecia gregarious, superficial ovate-globose, black, with a few, 

 short, spreading, bristle- like hairs around the base. Ostiolum 

 minute, acutely conical. Asci not seen. Sporidia oblong-fusoid, 

 3-4-septate, pale brown, 12-15 x 3-3 h>- 



On rotten wood, Bethlehem, Pa. (Schweinitz).
