RYVARDEN L. (2012): Type studies in Polyporaceae 27. Species described by P. Ch. Hennings. [Polyporaceae, types, taxonomy, nomenclature, Berlin herbarium] Czech Mycology 64(1): 13-21 (published: 2nd July, 2012)
abstract
103 polypores described by P. Ch. Hennings have been examined based on the available types. Nineteen species are accepted, 63 species are reduced to synonymy, the types of 19 species could not be found, while two names are illegitimate. Two new combinations are proposed: Tyromyces aquosus (Henn.) Ryvarden and Diplomitoporus daedaleiformis (Henn.) Ryvarden. These two species are provided with descriptions, while published recent descriptions are referred to for the other 17 accepted species.

KOTLABA F., POUZAR Z., RYVARDEN L. (1984): Some polypores, rare or new for Cuba. Česká Mykologie 38(3): 137-145 (published: 1984)
abstract
Two new coprophilous species of Coprobia Boud., C. hyphopila spec. nov. and C. sordida spec. nov. are described from Czechoslovakia. Taxonomic problems of the genera Coprobia and Cheilymenia Boud. are discussed. Regarding the genus Cheilymenia, the author proposes to separate all species with superficial apothecial hairs related to Cheilymenia theleboloides from the genus and transfer them to Coprobia on the basis of a similar excipular structure and a specific cyanophilic striation of ascospore perispore consisting of extremely low longitudinal ribs. The author considers the striation of the peelable perispore (together with pustules, warts or folds) a very important feature for classification of species of Coprobia including all species of Cheilymenia with “theleboloides” type of excipulum and hairs. Moreover, the author described and pictured an outstanding ascospore ornamentation which he has found in several other species of Cheilymenia considered smooth-spored till now (e.g. C. ciliata). One new combination has been made.
RYVARDEN L. (1976): On the identity of Acia sibirica Pil. and A. licentii Pil. Česká Mykologie 30(1): 38-40 (published: 1976)
abstract
The types of Acia sibirica Pil. and A. licentii Pil. have been examined. A. sibirica is a synonym of Protodontia piceicola (Kühn.) Martin, while A. licentii is transferred to the genus Radulodon Ryv. The combination Radulodon licentii (Pil.) Ryv. is proposed.
