Stroma very broadly effused, forming a thin (.7.")-! nnii.i. smooth, 

 whitish or gray crust which is flush with the surface^ of the surrounding 

 bark, irregularly dotted with the black ostiola. usually surrounded by a 

 black, sterile margin or circumsciibing line, substance hard and rigid, 

 black inside. Peritliecia in a single layer, not crowded, ovate, about .H 

 mm. high, sometimes reaching almost to the base of the stroma. Asci 

 abruptly contracted below into a short, stii)itate base. 17r)-22U x 1.1-17 mi-

On Fagus and Quercus. vicinity of F.loomington. Tiid. Also in Orange 

 County, Indiana. 



This spe( ics often extends in broad exjtanses for many feet along 

 dead, standing tree trunks. It is easily overlooked on beech because of 

 its similarity in color to the bark, but is readily identified by its black- 

 punctate character.

Stroma broadly effused, varying greatly in extent, sometimes 1-2 cm. 

 \\ ide and .5-10 cm. long, occasionally continuous or interruptedly contin- 

 uous for two or three feet in strips 1-3 cm. wide; 1-2 mm. thick; brown 

 or purple, changing to dark-purple or almost black ; margin of stroma 

 rounded and distinct; surface papillate from the slightly prominent peri- 

 tliecia which are .6G-1 mm. high, oblong or obovate, and are closely packed 

 in a single layer. Spores ovate, subacute at each end, opaque, 9-13x4.5-6 

 microns. No asci were present in our specimens. (B. & E. — Asci, spore- 

 bearing part, 50-60x7-8 microns. Spores 10-14 x5-(i microns.)
