Stigmatomyces tschirnhausii
Stigmatomyces tschirnhausii W. Rossi & M. Leonardi, in Hyde et al., Fungal Diversity 96: 118 (2019)
Index Fungorum number: IF828163; Facesoffungi number: FoF05177
Receptacle, distal portion of the free appendage and perithecial apex 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 tapering throughout, the basal cell abruptly narrow just above the foot, the suprabasal longer, the horizontal septum dividing the two cells associated with a slight constriction. Stalk-cell of the appendage rather short and stout, broadly heart-shaped, very prominent distally. Axis of the appendage consisting of four cells, the lower distinctly larger and darker, about twice as long as broad, the others gradually smaller, each bearing a pair of relatively large antheridia with strongly curved necks, the uppermost of which is spinose. Stalk-cell of the perithecium flattened and subtriangular; the cells above distinctly prominent externally. Perithecial venter relatively short and stout, symmetrically inflated, the spiral wall cells separated by thin furrows; the neck distinctly longer, almost isodiametric above the slightly spreading base; the tip very slightly bent and tapering; the lips strongly unequal, two being short, flattened and divergent, the other two elongate, forming together a tooth-like, suberect prolongation. Total length 280–400 μm; perithecium 50–70 × 175–225 μm; free appendage 55–70 μm. (Adopted from Hyde et al. 2019)
Known hosts and distribution: on sternites near apex abdomen, antennae and legs of Dasiops sp. (Diptera, Lonchaeidae) (Kenya). (Adopted from Hyde et al. 2019)
