Abstract :

Acanthocorticium brueggemannii gen. et sp. nov. is introduced based on specimens from Southern Brazil. This corticioid fungus is characterized by resupinate basidiomes with smooth to tuberculate hymenophore, a monomitic hyphal system with simple-septate hyphae, finely echinulate halocystidia, cylindrical to clavate, dextrinoid acanthophyses, and globose, hyaline, smooth, and thin-walled IKI- basidiospores. Phylogenetic analyses of a LSU data set and a combined data set of ITS and LSU were carried out and the new taxon was found to be related to cyphelloid fungi within the Agaricales. Descriptions and drawings of the microscopic features ofA. brueggemannii are provided. Keywords: acanthophyses, Aphyllophorales, Corticiaceae s.l., Cyphellaceae, Henningsomyces, Rectipilus. Acanthocorticium brueggemannii gen. et sp. nov. est introduit a partir de specimens du Bresil du Sud. Ce fongus est caracterise par des basidiomes resupines avec des hymenophores lisses a tubercules, un systeme d'hyphes monomitique avec d'hyphes generatrices a cloisons simples, halocystides a parois finement echinules, acantophyses dextrinoides cilindriques a clavees, et basidiospores globoses, hyalins, lisses et a paroi mince, IKI-. Les analyses phylogenetiques d'un ensemble de donnees de LSU et d'un ensemble de donnees combinee d'ITS et LSU ont ete effectuees et le nouveau taxon fut recupere et liee aux champignons cyphelles dans les Agaricales. On present les descriptions du nouveau genre et la nouvelle espece, ainsi que des dessins et caracteristiques microscopiques de A. brueggemannii. Mots-cles : acanthophyses, Aphyllophorales, Corticiaceae s.l., Cyphellaceae, Henningsomyces, Rectipilus.
