New species and new records in Marasmius sect. Sicci from China

During the re-examination of the Chinese Marasmius specimens of sect. Sicci preserved in the herbaria KUN and GDGM, four new species were discovered: Marasmius albostipitatus is characterized by an orange pileus, a white stipe, and the absence of pleurocystidia and caulocystidia; M. hygrocybiformis is recognized by an orange-red, plano-convex pileus, a grayish green hyaline stipe and medium large basidiospores; M. sparsifolius is characterized by an orange-white pileus, extremely distant lamellae not reaching the pileus margin; M. subabundans is similar to M. abundans in many respects, but has obviously smaller basidiospores and usually a paler pileus. In addition, M. coklatus, M. confertus var. parvisporus, M. hinnuleus and M. cf. occultatiformis are reported as new to China. All eight taxa are described and illustrated in detail according to the Chinese materials.
