Abstract Three new species of Terriera, T. guizhouensis, T. houjiazhuangensis, and T. ilicis are described and illustrated based on collections from Anhui, Guizhou, and Hubei provinces in China. Sequence analyses of ITS rDNA and the combined nrLSU and mtSSU supported the establishment of the new species. The specimens formerly identified as Lophodermium minus (syn. Terrierra minor) in China need further studies. Keywords 3 new taxa1 . Rhytismatales . Terriera . Phylogeny
Introduction In 1970, Eriksson erected the monotypic genus Terriera for T. cladophila (Lév.) B. Erikss (Eriksson, 1970). Johnston (1988, 1989) regarded the structure of ascomata as an important character for identifying Terriera. A phylogenetic analysis by Lantz et al. (2011) supported Terriera as monophyletic. Subsequently, many Lophodermium species which have typical ascomatal structures of Terriera have been transferred to Terriera (Johnston 2001). Up to now, 35 species in Terriera are recognized worldwide (http://www.indexfungorum.org/), and 17 species have been reported from China (Li et al. 2015; Zhang et al. 2015; Song et al. 2012; Zhou et al. 2012; Chen et al. 2013).

In the present study, some specimens of Terriera were collected from Anhui, Guizhou, and Hubei provinces in China, and described here as new species.
Materials and methods Morphological studies All observations were made from dried and dead herbarium material. Microscopic preparations were made in distilled water, Melzer’s reagent, 5% (w/v) KOH, or 0.1% (w/v) cotton blue in water. For observation of ascomatal outlines in vertical section, sections were mounted in lactophenol solution or cotton blue with pretreatment in water. Gelatinous sheaths surrounding the ascospores and paraphyses were observed in water or cotton blue. Measurements were made from 20 ascospores and asci for each specimen using material mounted in distilled water. Schematized drawings were made from microscopy preparations using dead specimens observed in water.
Molecular methods Genomic DNA was extracted from ascomata using NuClean Plant Genomic DNA Kit (CWB
