Abstract:

Two monotypic genera, Arthrocormus Dozy & Molk. and Noguchiodendron TN. Ninh & Pócs are reported as new distributional records for China. Arthrocormus schimperi is widely distributed in tropical Asia and Oceania, while Nsphaerocarpum is previously reported from Bhutan, India, Nepal and Thailand. Arthrocormus schimperi looks like some Leucobryaceae species and Nsphaerocarpum resembles Homaliodendron spp. We speculate these are the main reasons why they have been overlooked by collectors. The extremely brittle tips with a cylindrical appearance in the upper portion of leaves make Arthrocormus very distinguishable in the field, while the strongly curled branch in dry condition is the most diagnostic feature of Noguchiodendron. Illustrations for both taxa reported are provided for reference purposes.

Key words: New distributional records, Arthrocormus, Noguchiodendron, Bryophyte inventory, Yunnan
