g. Pleomassaria siparia) and may be symmetrical (e.g. Asteromassaria macrospora) or highly asymmetrical (e.g. Splanchnonema GS-1101 pustulatum). The peridium ranges from thick-walled textura angularis (e.g. Asteromassaria macrospora) to thin-walled compressed cells (e.g. Splanchnonema pustulatum) and medium textura prismatica (e.g. Pleomassaria siparia). Anamorphs also vary distinctly, Prosthemium in Pleomassaria siparia, Scolicosporium in Asteromassaria macrospora but no anamorphic
stage reported for Splanchnonema pustulatum. Furthermore, Asteromassaria pulchra clusters in Morosphaeriaceae in this study, thus here we tentatively assign Asteromassaria in Morosphaeriaceae (Plate 1). There seems to be considerable confusion in this family, especially when Pleomassaria siparia forms a robust phylogenetic clade with Melanomma pulvis-pyrius (Melannomataceae).
Thus in this study, Pleomassariaceae is restated as a separate family from Melannomataceae. Therefore, fresh collections of the types of these genera are needed for molecular analysis and to establish which characters are important for classification. Pleophragmia Fuckel, Jb. nassau. Ver. Naturk. 23–24: 243 (1870). (Sporormiaceae) Generic description Habitat terrestrial, saprobic (coprophilous). Ascomata small- to medium-sized, gregarious, immersed to erumpent, globose to subglobose, black, coriaceous; apex with a short papilla, or sometimes forming an ostiolar pore. Peridium thin, composed of several layers of thin-walled cells of textura angularis. Selleckchem NSC 683864 Hamathecium of dense, delicate pseudoparaphyses. Asci 8-spored, see more bitunicate, fissitunicate, clavate to cylindro-clavate, with a relatively long pedicel and an ocular chamber. Ascospores muriform, narrow oblong IMP dehydrogenase to cylindrical with rounded ends, dark brown, constricted at each septum. Anamorphs reported for genus: none.
