Abstract |
A new species of Orbilia related to O. luteorubella is described
mainly based on morphological characters of its asexual
morph and molecular data. The sexual morph does not significantly
differ from O. luteorubella, whereas the asexual
morph obtained from its ascospore isolate resembles members
of the non-predacious genus Dactylella, because it has
fusiform phragmoconidia borne singly at the apex of conidiophores.
Phylogenetic analysis showed that this strain clustered
with a clade that included available strains of the O.
luteorubella aggregate and was distant from all analysed Dactylella
species. Within this clade, the new strain fell between
species with filiform conidia and those of a Pseudotripoconidium
anamorph. By combining morphological and phylogenetic
analyses, we conclude that our isolate belongs to a
new taxon. Pleomorphism of the new taxon is described and
discussed. |
