ABSTRACT: Three new species Trimmatothelopsisanthracina, 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. Trimmatothelopsisanthracina is characterized by carbonized apothecia, a biofilm at the immature apothecia base, and IKI+ blue turning red hymenial gel. Trimmatothelopsisknudsenii is characterized by rimose thallus, numerous reddish brown apothecia, and IKI+ blue turning red hymenial gel. Trimmatothelopsisshandongensis is characterized by dull brown thallus, thick hymenium, IKI+ red hymenial gel, and small asci.
