NEW SPECIES AND NEW VARIETIES OF THE GENUS CYATHUS

In this paper four new species and two new varieties are reported. The new species are Cyathus neimonggolensis Liu et Y. M. Li, C. discostipitatus Liu et Y. M. Li, C. taiyuanensis Liu et Y. M. Li and C. hirtulus Liu et Y. M. Li. The new varieties are C. tianshanensis Liu et Cao var. tomentosus Liu, Cao et Y. M. Li and C. annulatus Brodie var. wuyishanensis Liu et Y. M. Li. C. neimonggolensis Liu et Y. M. Li is close to C. novae-zeelandiae Tul, but this new species is distinguished from the latter by annulate colourous peridium, compress-orbicular peridiola, ovoid spores somewhat pointed at one end. C. discostipitatus Liu et Y. M. Li is close to C. colensoi Berkeley, but distinguished from the latter by its discoid bases, smaller peridiola and spores, thicker walled spores and peridium. C. taiyuanensis Liu et Y. M. Li is close to C. berkeleyanus (Tul.) Lloyd, but distinguished from the latter by ovoid to broad-ovoid spores, somewhat pointed at one end, epispore 0.4μm thick. C. hirtulus Liu et Y. M. Li is close to C. wutaishanensis Liu, Shangguan et Yuan, the differences are the forme(?)aying larger ellipsoid peridiola, somewhat curved spores, larger peridium covered with downward pointing brown shaggy. C. tianshanensis Liu et Cao var. tomentosus Liu, Cao et Y. M. Li is distinguished from the original variety by peridinm covered with short tufted hairs, exterior different colours and stipitate bases. C. annulatus Brodie var. wuyishanensis Liu et Y. M. Li is distinguished from the original variety by compress-orbicular peridiola, ellipsoid to oblong-ellipsoid spores, epispore 1.5—2μm thick, basal emplacement conspicuous. Type specimens of above new species and new varieties are deposited in the Mycological Herbarium of Shanxi University (MHSU), Taiyuan, Shanxi Province, China.
