carnose, 2-3 mm. across, discoid, obsoletely margined, brown, 

 yellowish-white inside, contracted below, centrally attached, 

 clothed with brown, bristle-like, septate hairs, 100-200 x 4 /«, 

 convex or plane above and slightly roughened by the papilli- 

 form ostiola. Perithecia buried in the stroma, sub-distichous, 

 ovate, about ^ mm. high. Asci, clavate-cylindrical, swollen 

 at the tip, looxio/^ (or about that). Sporidia navicular-ob- 

 long, or inequilaterally elliptical, brown, 7-8x3-3/^ /«.

Cespitose. Perithecia narrowed-ovate, about i x /^ mm., 

 clothed with a yellow, granulose-furfuraceous coat, crowded 

 in tufts, 2-3 mm. across, 20-100 together. Ostiolum obtuse, 

 broad-papilHform, amber-colored, soon perforated. Asci cla- 

 vate, p. sp. 80-100 X 12-15 /z, with evanescent paraphyses, 

 8-spored. Sporidia irregularly crowded, large, broad-oblong- 

 fusoid, 30-38x8-10//, yellowish-brown, uniseptate and slightl}'- 

 constricted, each cell 3-5-nucleate, finally assuming a striate 

 appearance, from being filled, apparently with linear-cylin- 

 drical bodies. 



This seems to be a well marked species; on account of the 

 nuclei, sometimes apparently 3-5-septate, but there is only 

 one true septum.
