NEW IOWA FUNGI. a^ 



DiAPORTiiE (Euportiie) cornicola £//is & Ilolzvay. 



Perithecia scattered or 2-4 valsoid-aggregated, globose, 

 whitish or gray inside, ^2-% mm in diameter, buried in the 

 inner bark, their bases slightly penetrating the wood and their 

 stout, short-cylindrical, perforated ostiola, piercing"and slightly 

 raising the epidermis but hardly rising above it. Asci oblong- 

 fusoid, p. sp. 40-45 X 8//, 8-spored. Sporidia oblong, hyaline, 4- 

 nucleate, uniseptate and constricted, obtuse, io-i/\x 3/4-^/4 /'■ 



When the epidermis is peeled off the tips of the scattered 

 ostiola resemble small perithecia. There is no discoloration 

 of the bark or wood. This is very different from D. albocar- 

 nis E. and E . on the same host.
