Stigmatomyces papei

Stigmatomyces papei W. Rossi & M. Leonardi, in Hyde et al., Fungal Diversity 96: 117 (2019)

Index Fungorum number: IF828162; Facesoffungi number: FoF05178

Perithecium pale reddish brown; the rest of the thallus is almost hyaline or faintly tinged with reddish brown, with the exception of the lower cell of the free appendage which stands out with brilliant rusty red. Receptacle rather short and stocky, tapering throughout, the basal cell subtriangular with its content contracted above, the suprabasal distinctly longer. Stalk-cell of the appendage relatively long and narrow, distally prominent. Free appendage slender and attenuate, straight or sigmoid, its axis usually consisting of 9 cells, each bearing a pair of slightly diverging antheridia arranged in two rows, except for the uppermost cell, which bears three superimposed antheridia. Stalk-cell of the perithecium large, longer than broad, its outer margin overlapped for most of its length by the secondary stalk-cell, which is only slightly smaller. Perithecial basal cells subequal, large, longer than broad. Perithecium longer than the rest of the thallus, slender and elongate, the venter oblong, the neck hardly distinguished, about as long as the venter, very slightly tapering towards the tip and ending with two large and unequal outgrowths, of which the shorter is broadly ovoid, the other beanshaped and bending outwards. Total length 575–640 µm; perithecium 60–70 × 340–380 µm; free appendage 105–140 µm; ascospores 55 µm. (Adopted from Hyde et al. 2019)

Known hosts and distribution: on tergites of Plagiostenopterina submetallica (Loew) (Diptera, Platystomatidae) (Tanzania). (Adopted from Hyde et al. 2019)
