Additions to the genus Savoryella (Savoryellaceae), with the asexual morphs Savoryella nypae comb. nov. and S. sarushimana sp. nov.

Abstract

Two asexual trichocladium-like species were recorded from coastlines in Japan and Thailand. Phylogenetic analysis of multi-gene sequence data placed them in Savoryella (Savoryellaceae), grouping with an unidentified strain isolated from submerged wood in a saline environment, but distinct from other Savoryella species. In this paper, we propose a new combination as Savoryella nypae based on Trichocladium nypae and a new species Savoryella sarushimana. Savoryella sarushimana differs from S. nypae in having larger conidial dimensions, with a rough to spiny surface and the proliferation of conidia. Detail morphological features coupled with sporulation in culture of the new taxa are illustrated. Notes on the phylogenetic placement of the discussed taxa and emendation of the genus Savoryella are provided.
