Two new species of Brachytrycherus from China, Brachytrycherus conaensis sp. n. and Brachytrycherus curviantennae sp. n. are described and illustrated. Brachytrycherus conaensis sp. n. is the first species of the Handsome Fungus Beetles recorded feeding on Ascomycetes. A key to the species of Brachytrycherus known in China is provided.

The addition of cottonwood and ash sapwood powder to YPSSl2 medium influenced the mycelial growth of 13 species of freshwater lignicolous Ascomycetes and Hyphornycetes. These species fall into three groups with respect to their responses to the presence of leached or non-leached wood powder. Neither wood type showed strong inhibitory effect on the mycelial growth of the species. Leaching di...

Orbiliomycetes is one of the earliest diverging branches of the filamentous ascomycetes. The class contains nematode-trapping fungi that form unique infection structures, called traps, to capture and kill free-living nematodes. The traps have evolved differently along several lineages and include adhesive traps (knobs, nets or branches) and constricting rings. We show, by genome sequencing of t...
