Daldinia concentrica

(Daldinia concentrica) is a wood-inhabiting fungus of the Xylariaceae. A molecular study of 35 collections of Daldinia from 11 different plant species revealed 5 different taxa for northern Europe: Daldinia concentrica, D. cf. fissa, D. grandis, D. loculata, D. cf. petriniae (the last three species almost exclusively on burnt wood), but these entities do not form a monophyletic block in the phylogenetic tree derived from ribosomal DNA analyses.15 A comparative study of the "perfect" and "imperfect" states of Daldinia concentrica and D. vernicosa confirmed their different genetic identities
