Abstract

Three new species Trimmatothelopsis anthracina , T. knudsenii , and T. shandongensis are reported from the eastern coast of China, based on morphological, chemical and molecular data (ITS, LSU, and mtSSU). All three new species have IKI+ blue ascus. Trimmatothelopsis anthracina is characterized by carbonized apothecia, a biofilm at the immature apothecia base, and IKI+ blue turning red hymenial gel. Trimmatothelopsis knudsenii is characterized by rimose thallus, numerous reddish brown apothecia, and IKI+ blue turning red hymenial gel. Trimmatothelopsis shandongensis is characterized by dull brown thallus, thick hymenium, IKI+ red hymenial gel, and small asci. Comprehensive descriptions, detailed illustrations, and phylogenetic analysis of the new taxa are presented. Additionally, a worldwide key to Trimmatothelopsis species, including 21 species, is provided.
