On outer bark of white oak. Xewfield, X. J. 



We have referred this to L. mawospomm, 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. Jotiru. Mycol. II, p. 44. 



Perithecia buried in the substance of the wood, globose, J-J mm. 

 diam. Ostiola erumpent, narrow, only slightly prominent. Asci ela- 

 vate-cylindrical, 90-100x12-15 p, 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 u, with a shriveled appearance. The perithecia 

 are oreedilv eaten out by a small beetle. Allied to L. scelestvm.

 De Xot, in its immersed and smaller perithecia, and its somewhat 



smaller sporidia.
