Stigmatomyces vikhrevii
Stigmatomyces vikhrevii W. Rossi & M. Leonardi, in Hyde et al., Fungal Diversity 96: 119 (2019)
Index Fungorum number: IF828164; Facesoffungi number: FoF05179
Receptacle almost hyaline; the rest of the fungus is unequally colored with diluted rusty red, with the perithecial venter and lower cell of the free appendage distinctly darker. Receptacle rather stout, nearly uniform, with the basal cell abruptly tapered at the base and the suprabasal longer, sometimes slightly broader above. Stalkcell of the appendage short and stout, its outer margin more or less convex. Free appendage also short and stout, with the axis composed of three cells, the lower distinctly darker, each producing a pair of large antheridia, the uppermost of which bears a tiny spine. Stalk-cell of the perithecium much compressed, the secondary stalk-cell larger, with lower and outer convex margins. Perithecial venter elliptical in outline, its wall cells very slightly spiral with a verruculose surface, the verrucosity disposed more or less transversely; passing without abrupt transition to the base of the paler, smooth and shorter neck; the latter erect, its margins very slightly concave, distally broader at its junction with the stout, tapering tip; the subtruncate apex ends in four lips, three of which are very small, subequal and flattened, the fourth rounded and more prominent. Total length 210–415 μm; perithecium 45–60 × 140–220 μm; free appendage 50–55 μm; ascospores 40–45 μm. (Adopted from Hyde et al. 2019)
Known hosts and distribution: on the tergites near the apex of the abdomen of Discomyza maculipennis (Wiedemann) (Diptera, Ephydridae) (Malaysia). (Adopted from Hyde et al. 2019)
