NEW SPECIES,NEW VARIETY AND NEW RECORD OF THE GENUS CYATHUS FROM CHINA

In this paper three new species,one new variety and one new record of China are reported and described.The new species are Cyathus sichuanensis Liu et Y.M.Li,C.guandishanensis Liu et Y.M.Li and C.yunnanensis Liu et Y.M.Li.The new variety is C.wutaishanensis Liu,Shangguan et Yuan var. yuanquensis Liu et Y.M.Li.The new record of China is C.badius Kobayasi.C. sichuanensis is close to C.minimus Pat.,but the latter is distinguished from this new species by its absence of discoid base,and smaller peridium,spore and peri- diolum.C.guandishanensis is close to C.pullus Tai et Hung.,but this new species is distinguished from the latter by its discoid base,larger peridiolum,and peridium not plicate and externally covered with tufted hairs.C.yunnanensis is distinguished from any other species in the Group VII (Brodie,1975) and any other groups of Cyathus mainly by its broadly ellipsoid to subglobose spores.C.wutaishanensis var. yuanquensis is distinguished from the original variety by peridium covered with straw colored and downward pointed hairs,exterior light in color,interior broadly plicate and larger spores. Type specimens of the above new species and new variety except Cyathus yunna- nensis are all deposited in the Mycological Herbarium of Shanxi University(MHSU), Shanxi Province,China.C.yunnanensis is deposited in the Herbarium of Mycolo- gicum Instituti Microbiologici,Academia Sinica (HMAS),Beijing,China.
