摘要
Abstract
Based on morphological,chemical,and phylogenetic analyses,a new species of the lichenized fungal genus Synarthonia,Synarthonia hainanensis,is described.This species is currently known only from Hainan Province.Synarthonia hainanensis is characterized by whitish-green thallus,short lirelliform to elongate,reddish-brown to black and epruinose ascomata,I+reddish-purple hymenium,K/I-blue distinct ocular chamber in the asci,hyaline,4-septate,and oblong-ovoid ascospores with the size of 18-24.5×6.5-9.5 µm.Molecular data,detailed taxonomic description,and images illustrating the morphological and anatomical characteristics of the new species are provided.A discussion on the differences between the new species and its similar species is also included.In addition,a key to 25 species of this genus is presented herein.关键词
