The new species Tubakia chinensis, collected on living leaves of Castanea henryi (Fagaceae) in China, Jiangxi Province, is described, illustrated and compared with other species of the genus Tubakia. T. chinensis is morphologically comparable with T. japonica and T. seoraksanensis, two Asian species characterised by having similar conidia, but differs from the two species in the size of conidia, conidiogenous cells and scutellum. An additional undescribed Tubakia found on Castanea henryi together with T. chinensis is briefly described, illustrated, discussed and tentatively referred to as Tubakia sp. The species assigned to Tubakia are discussed and keyed out. 2015-03-09 14:44:58 UTC prep SP14e Foliar and Fungal pathogens Lydia Hönig lydia.hoenig@botanik.uni-halle.de Steffen Bien steffenbien@uni.de Braun, U., Bien, S., Hönig, L., & Heuchert, B.
