| Abstract: | The molecular phylogeny of nuclear LSU rDNA sequences (D1/D2 domain), ITS regions, and beta-tubulin gene (tub2) showed that the seven strains of Shiraia-like fungi obtained from fresh bamboo tissues as endophytes were closely related to Shiraia bambusicola and had three distinctive lineages (groups A-C). The closest group (group A) to S. bambusicola produced distinctive prawn-shaped conidioma-like structures that differed from conidiomata in the anamorph of S. bambusicola. Currently, none of the morphological structures and molecular database records were compatible with our Shiraia-like fungi. These results reveal that Shiraia-like fungi group A is supposed to be a new species that should be assigned into a novel genus/species related to S. bambusicola. |
