Type study of one species described in the genus Ceracea

Ceracea aureofulva Bres. is presented. New combination Cerinomyces aureofulvus (Bres.) Malysheva is proposed. The detailed taxonomic description and illustration of the specimen are given.


INTrodUcTIoN
The genus Ceracea cragin has originally accommodated representatives with different morphological features, so it was considered as an artificial genus.Some species characterized by corticioid habit, subclavate or clavate bifurcate dacrymycetaceous basidia and cylindrical aseptate or 1-3-septate spores were transferred to Cerinomyces G. W. Martin (Martin 1949;Parmasto 1961;McNabb 1964), now placed in the Dacrymycetaceae Bref.
This new contribution to studies on the genus Ceracea presents the result of the isotype revision of Ceracea aureofulva Bres., which specimen is available in the Mycological herbarium of the Botanical Institute (le) received as exsiccatae Fungi saxonici no.1909.Based on the morphological characteristics observed, C. aureofulva is considered as a species of Cerinomyces and the new combination is introduced in this paper.
The specimen studied represents teleomorph stage of fungus.our description of all morphological features corresponds to the type description (Bresadola in Krieger 1906) quite well.It is interesting that according to information on the electronic data bases (MycoBank -www.mycobank.org,Index Fungorum -www.indexfungorum.org) anamorph stage of this species is only known and teleomorph connection is not recorded.however, the data about holotype material studed is known also from the acTa MycoloGIca publication of Martin (1949) where features examined agreed with the protologue description except the septation of spores.

Microscopical features are described from examined material mounted in congo red and 1% Koh.Microscopic measurements and drawings were made with Micmed 2-2 and axioImager a1 microscopes.Basidiospore dimensions are based on observation of 20 spores.spore length to width ratio is reported as Q.Mean values for Q are designated as Q*.
nOtes.This species is similar to Cerinomyces altaicus Parmasto and C. lagerheimii (Pat.)McNabb but differs from the former one by longer spores and from the latter one by having clamp connections.
