On outer bark of white oak, Newfield, N. J. 



We have I'eferred this to X. macrospon.im, 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. erosuin, E. & E. Journ. Mycol. II, p. 44. 



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

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

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

 Sporidia subljiseriate 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 perithecia 

 are greedily eaten out by a small beetle. Allied to X. scelesfum, 

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

 De Not, in its immci-sed and smaller perithecia, and its somewhat 

 smaller sporidia.

Perithecia semiimmersed, black, broad (|-1 mm.). Ostioluui 

 prominent, extending ^-| way across the perithecium. Asci clavate, 

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

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

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

Perithecia scattered, immersed, coriaceous, globose or elliptical, 

 i-3 mm. diam. Ostiolum alone erumpent, small, narrow and com- 

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

 ridia obliquely biseriate, oblong-fusoid, 5-7-septate, brown, 25^5 x 

 8-10 /i (40-50 X 10 [I, Oke.) 



On decorticated, weather-beaten oak, maple, Viburnum and pear, 

 Newfield, N. J., on decaying wood of pear tree, Helderberg Mts.,

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

 or less constricted, especially at the middle septum.
