Abstract
Bjerkandera is a worldwide polypore genus characterized by the pileate grayish basidiomes, often becoming darker when dried, and monomitic hyphal system. Tyromyces atroalbus is a rare Brazilian species re-discovered in recent surveys in São Paulo State. Even though it has been placed in Tyromyces, it presents a characteristic darkening of basidiomes when touched or dried, a feature absent in other species of the genus. In order to understand the evolutionary relations of T. atroalbus with Bjerkandera and Tyromyces and find its proper phylogenetic placement, morphological and molecular studies were carried out. Specimens from Brazil and Mexico were studied morphologically and selected specimens were used for DNA sequence analyses of internal transcribed spacer (ITS) and large subunit (LSU) of ribosomal RNA genes and translation elongation factor 1-alpha genes. Type specimens of T. atroalbus and T. humeana were also morphologically examined to confirm their possible synonymy as well as to confirm the identity of the recent collections. Molecular and morphological characters of T. atroalbus place the species in Bjerkandera. Our results also revealed that the specimens from Brazil and Mexico represent two distinct species. Therefore, the new combination Bjerkandera atroalba and description of new species B. centroamericana is published. In addition, the type study of T. atroalbus and T. humeana supports their synonymy.
