 Exsicc. EU. N. A. F. 1341. 



Perithecia loosely gregarious, innate, globose-papillate, black, the 

 ostiola piercing the blackened epidermis. Asci cylindric-clavate, 120 x 

 20 ft, short-stipitate ; paraphyses iiliforni, generally dichotomous. Spo- 

 ridia obliquely uniseriate or biseriate, oblong-fusoid, ends rounded, 

 25-30 X 9-10 fi, 3-septate, constricted at the septa, 4-nucleate, the two 

 inner cells darker, the end cells subhyaline.

L. algida, Rostr. Fungi Gronl. p. 560 (No. 175). 



Perithecia globulose, scattered, 160 /i diam. Asci cylindric-cla- 

 vate, somewhat curved, 50-54x12 fi, without paraphyses. Sporidia 

 obliquely uniseriate, oblong, often somewhat curved, yellow, 3-septate, 

 16-20x6-7 11.

L. Xerophylli, Ell. Am. Nat. 1883, p. 316. 



Exsicc. BU. N. A. F. 1340. 



Perithecia scattered, subglobose, 150-190 fi diam., semiimmersed. 

 Ostiolum obtuse with a rather large opening, elevating and splitting 

 the epidermis, by which it is partly covered. Asci oblong or oblong- 

 clavate, sessile, 55-60x15 fx, with obscure paraphyses. Sporidia bi- 

 seriate, broad-fusoid, slightly curved, hyaline at first with 4 large nu- 

 clei, becoming 3-septate, slightly constricted at the septa, 19-25 x 

 5_6i n. Doubtfully distinct from L. hysterioides.

Perithecia gregarious, punctiform, erunipent, emergent through' 

 cracks in the epidermis, black, subconvex, papillate. Asci clavate,
