Rem.vrks. Dietel (9) described this species from the specimen col-

 BracJiypodiinn by the naked telcutosori and non-coronato teleiitospores and 

 by the invariable occurrence of the sori on the culm.

Remarks. By the kindness of Mr. N. Nambu, I have been able to

 of this species differ from those on Calamagrostis by the darker color of 

 their epispore.
