(2016): Lopadostoma taeniosporum revisited and a new species of Coniochaeta
SYDOWIA. 2016; 68: 87-97. FullText FullText_BOKU

Abstract:: Phylogenetic analyses of ITS-LSU rDNA sequence data revealed that Anthostoma taeniosporum, currently classified as Lopadostoma taeniosporum, does not belong to Xylariales but to the genus Coniochaeta (Coniochaetales), in which it is formally combined. Anthostoma taeniosporum is epitypified with a recent specimen for which sequence data are available. Coniochaeta taeniospora differs macro-morphologically from most other species of Coniochaeta in the immersed habit of ascomata. Furthermore, this species is well defined by its light brown, obtuse hairs, green peridium in KOH, and relatively large, ellipsoid to ovoid ascospores. A Spanish specimen initially identified as Coniochaeta taeniospora turned out to be phylogenetically distinct from the other two accessions sequenced, and is described as the new species Coniochaeta navarrae. This species differs morphologically from C. taeniospora in ascomatal habit, lack of clearly developed hairs on the peridium, colour of the peridium in KOH, and size of the ascospores, which are slightly larger and sometimes show a hyaline sheath in C. navarrae.
