Arcyria imperialis Q. Wang & Yu Li 2006

Under the SEM, spore ornamentation is formed by short and regulary distributed baculae 0.1–0.15 µm in length, of the baculate type in the sense of Rammeloo (1974). Among a majority of smaller warts larger warts are scattered that are also visible by LM. Examination by SEM reveals that they are made up of 2–5 baculae joined to form a larger wart (0.2–0.3 µm).

Syntypus, box B.M. 4068 [BM001085196]: This sample has been obtained from a culture from spores of the type, and it is better preserved than the lectotype. It consists of numerous sporocarps and the morphological and microscopic characters of this species are more uniformly developed compared to the lectotype specimen. | Published as part of Moreno, G., Castillo, A. & Thüs, H., 2022, Critical revision of Trichiales (Myxomycetes) at the Natural History Museum London (BM), pp. 1-20 in Phytotaxa 567 (1) on page 2, DOI: 10.11646/phytotaxa.567.1.1, zenodo.org/record/7137881
