Abstract

Molecular phylogeny and morphological characteristics of collections of diatrypaceous fungi from Guizhou Province, China, lead to the establishment of a new genus, Stromatolinea, and the identification of four new species and two new combinations. The taxa were found growing on the dead culms of Phyllostachys bamboo. The new genus is distinguished by its well-developed, discrete linear stromata with yellow interior tissue and allantoid subhyaline ascospores. The newly described species are Stromatolinea grisea, S. guizhouensis, S. hydei, and S. xishuiensis. Additionally, two new combinations, Stromatolinea linearis and S. phaselina, are proposed based on comparative analysis and morphology. Phylogenetic analyses were conducted using ITS and TUB2 sequences. The study includes comprehensive morphological descriptions, illustrations, and a phylogenetic tree depicting the placement of the new taxa.
