Dothideomycetes » Balladynaceae


Balladynopsis Theiss. & Syd., Annls mycol. 15(6): 475 (1918) [1917].

 Index Fungorum number: IF 506; Facesoffungi number: FoF 07952, 9 morphological species (Species Fungorum, 2020), molecular data unavailable.

Parasitic on living leaves. Sexual morph: Ascomata superficial, solitary, scattered, globose to subglobose, black, with apical pore, seated on mycelium colonies, radial hyphae, branched, with hyphopodia-like structures, dark brown, with setae, thickened, black, apex subacute and bright, lacking pseudoparaphyses. Peridium comprising 2–3 layers of relatively large, hyaline to dark brown cells of textura angularis. Asci 8-spored, bitunicate, globose to subglobose, sessile, apically thickened and rounded. Ascospores multi-seriate, fusoid to ellipsoid, oblong, upper cell wider, apex rounded, tapering towards the narrow and subacute base, 1-septate, supra-median, hyaline when immature, brown at maturity, smooth to slightly verruculose. Asexual morph: Undetermined (Adapted from Boonmee et al., 2017).


Type species: Balladynopsis philippinensis Syd. & P. Syd.


     Notes: Balladynopsis was introduced by Theissen & Sydow (1917) based on the species B. philippinensis (≡ Henningsomyces philippinensis Syd. & P. Syd.). Balladynopsis is unique in having superficial hyphae with hyphopodia, subglobose asci and 1- septate ascospores. The systematic position of Balladynopsis is not clear and is currently in Balladynaceae. Fresh collections with DNA sequence data are needed to confirm the taxonomic placement of Balladynopsis.
