New species of Hydnotrya (Ascomycota, Pezizomycetes) from southwestern China with notes on morphological characteristics of 17 species of Hydnotrya

More specimens of Hydnotrya have been collected from southwestern China in recent years. Morphological and molecular analyses showed that they belonged to three species of Hydnotrya, of which two are new to science, H. oblongispora and H. zayuensis. The third one was H. laojunshanensis, previously reported in 2013. The new species are described, and their relationship to other species of Hydnotrya is discussed. H. laojunshanensis is re-described in more detail. The main morphological characters of 17 species of Hydnotrya are compared and a key to them is provided as well.
