THE CULTURAL CHARACTERS, STRUCTURE OF THE FRUIT BODY, AND TYPE OF INTERFERTILITY OF CERRENA UNICOLOR (BULL. EX FR.) MURR.

Abstract

The cultural characters and morphology and construction of the fruit body of Cerrena unicolor (Bull, ex Fr.) Murr. are described. In the cultures and in the fruit bodies clamp connections are present on thin-walled as well as thick-walled hyphae. Pairings between cultures derived from single spores showed the bipolar type of interfertility. Conspecificity of some of the collections studied was confirmed by means of the "Buller phenomenon". Cerrena unicolor differs from type species of the genera Coriolus Quel., Lenzites Fr., Trametes Fr., and Daedalea Fr., to which it has been referred, in the morphology of the hyphae. It differs further from the type species of the first three genera by possessing the bipolar type of interfertility and from the type species of the fourth by possessing extracellular oxidase.
