Abstract in another language

The tropical genus Thamnomyces is characterized by having wiry, black, brittle stromata andearly deliquescent asci, lacking an amyloid apical apparatus. Thamnomyces is regarded as amember of the Xylariaceae, because the morphology of its ascospores and anamorphicstructures are typical for this family. However, its relationship to other xylariaceous generaremained to be clarified. Cultures of three Thamnomyces species were obtained and studiedfor morphological characters and their secondary metabolite profiles as inferred from highperformance liquid chromatography hyphenated by mass spectrometric and diode arraydetection (HPLC-MS/DAD) were also compared. Cultures of Thamnomyces closelyresembled those of the genera Daldinia and Phylacia and even produced several secondarymetabolite families that are known to be chemotaxonomic markers for the aforementionedgenera. These findings were corroborated by a comparison of their 5.8S/ITS nrDNAsequences We conclude that Thamnomyces, Daldinia and Phylacia are derived from the sameevolutionary lineage, despite these genera drastically differ in their stromatal morphology andanatomy. Along with Entonaema and Rhopalostoma, these fungi comprise an evolutionaryderived lineage of the hypoxyloid Xylariaceae. A new species of Thamnomyces is erected,and preliminary descriptions of three further, potentially new taxa are also provided.
