(S reg. nr F8934 type, F8935 isolectotype, as Leptosphaeria saginata). Notes Morphology Mixtura was formally established by Eriksson and Yue (1990) as a monotypic genus

represented by M. saginata based on its immersed and thin-walled ascomata, sparse, broad pseudoparaphyses, sac-like asci with a short pedicel and thick apex. Mixtura has a “mixture” of characters found in other pleosporalean genera. The peridium structure is comparable with Phaeosphaeria, the ascospores with Trematosphaeria and asci with Wettsteinina (Eriksson and selleck chemical Yue 1990). According to the structure of ascomata and hamathecium, Mixtura was provisionally assigned to Phaeosphaeriaceae (Eriksson and Yue 1990). Phylogenetic study None. Concluding remarks Morphologically, the sparse broad pseudoparaphyses and sac-like asci with a thick apical structure in Mixtura seem more comparable with the generic type of Teratosphaeria (T. fibrillose Syd. & P. Syd., Teratosphaeriaceae, Capnodiales, Dothideomycetidae) than that of Phaeosphaeria (P. oryzae). The heavily

pigmented, multi-septate ascospores and the persistent pseudoparaphyses of Mixtura however, differ from those of Teratosphaeria. Thus, here we assign Mixtura under Teratosphaeriaceae as a distinct genus until aminophylline phylogenetic work is carried out. Montagnula Berl.,

Icon. fung. (Abellini) 2: 68 (1896). (Montagnulaceae) Generic description Habitat terrestrial, saprobic. Ascomata buy TSA HDAC small- to medium-sized, immersed to erumpent, gregarious or grouped, globose to subglobose, black. Hamathecium of dense, narrowly cellular, septate pseudoparaphyses.
