Hypocrea britdaniae and H. foliicola: two remarkable new European species

Mycologia. 2012 Sep-Oct;104(5):1213-21. doi: 10.3852/11-429. Epub 2012 Apr 13.

Abstract

Two new species of Hypocrea are added here to the European funga. Hypocrea britdaniae, a fungus with unknown anamorph and large, conspicuous stromata resembling basidiomata of a corticiaceous fungus, is a sister species to the Longibrachiatum clade, while H. foliicola, a leaf-dwelling species that forms pulvinate stromata, is recognized as an additional member of the pachybasium core group. Hypocrea foliicola sporulates in culture in a reduced verticillium-like manner, while it produces a white, typical pachybasium-like anamorph in nature. Ecologically H. foliicola is remarkable in inhabiting leaves, a substrate rarely recorded for Hypocrea. All relevant morphological teleomorphic and anamorphic traits are given. The phylogenetic placement of the new species within Hypocrea/Trichoderma was determined with combined analyses of rpb2 and tef1 exon sequences.
