A phylogenetic analysis of Antrodia s.l. based on nrDNA ITS sequences, with emphasis on rhizomorphic European species

The rhizomorphic European species of Antrodia, belonging to the traditionally called Antrodia radiculosa group, are investigated. On the basis of morphological and molecular analysis, the genus Fibroporia is supported. Specimens from Central Europe previously ascribed to Antrodia radiculosa constitute a species of their own, and are herein described as Fibroporia bohemica. Moreover, a new combination, Fibroporia citrina, is proposed.
