Three new species of Phaeoclavulina from China are described: Phaeoclavulina bicolor, P. echinoflava, and P. jilinensis. Recognition of the new species is supported by morphological and molecular evidence. Phylogenetic analyses of concatenated ITS1–5.8S–ITS2 and nuclear large subunit sequences support the establishment of the new species and their placement within the Phaeoclavulina clade. A key to the known Phaeoclavulina species in China is provided.

Two new species of Trechispora indigenous to southern China, T. laxa and T. tongdaoensis, are described and illustrated, and the first record of T. khokpasiensis in China is reported. Molecular phylogenetic analyses of the concatenated nuclear rDNA ITS1–5.8S–ITS2 and nuclear large subunit sequences supported the inclusion of the three species within the Trechispora clade, together with species formerly classified in Scytinopogon. The new species are similar in micromorphology to species of Trechispora (as traditionally circumscribed) but are distinguished by having coralloid basidiomata. A key to the known coralloid Trechispora species in China is provided.
