On outer bark of white oak. Xewfield, N. .). 



We have referred this to L. macrosporum,Speg., though we have 

 not seen any appendages on the sporidia or any hyaline envelope, but 

 as the specimens are mature, these may have disappeared. 



L erosum, E. & E. Journ. Mycol. II, p. 44. 



Peritheeia buried in the substance of the wood, globose, |-| mm. 

 diam. ( )stiola erumpent, narrow, only slightly prominent. Asei cla- 

 vate-cylindrical, 90-100x12-15 /i, with abundant filiform paraphyses. 

 Sporidia subbiseriate above, oblong-fusoid or subnavicular, about 

 5-septate, hyaline at first, then yellowish and finally nearly opake, 

 mostly 20-25 x 7-8 //, with a shriveled appearance. The peritheeia 

 are greedily eaten out by a small beetle. Allied to L. scelestum, 

 C. & E., but with smaller sporidia. Differs from L. macrostomoides, 

 De Not, in its immersed and smaller peritheeia, and its somewhat 

 smaller sporidia.

 8-spored, 70x12 //. Sporidia biseriate, fusiform, widest above the 

 middle, curved, 6-8-septate, constricted, yellow-brown, cells minutely 

 binucleate, end cells paler, 30 x 9 //.

Peritheeia scattered, immersed, coriaceous, globose or elliptical, 

 \-\ mm. diam. Ostiolum alone erumpent, small, narrow and com- 

 pressed. Asci clavate-cylindrical, paraphysate, 100-120x15 //. Spo-

The sporidia are mostly 25-35 /i long and about 8 a wide, more 

 or less constricted, especially at the middle septum.
