Annellosympodia McTaggart, R.G. Shivas & U. Braun, Australas. Pl. Path. 36(6): 574 (2007).

Index Fungorum number: IF 510980; Facesoffungi number: FoF 08583, 1 morphological species (Species Fungorum 2022), no molecular data available.

Associated with leaf spot. Sexual morph: Unknown. Asexual morph: Conidiophores reduced to conidiogenous cells. Conidiogenous cells on minute pulvinate sporodochia, macronematous, dark brown, aseptate, verrucose, thick-walled, ampulliform, doliiform or obovoid, mono- or polyblastic, proliferating sympodially (rectilinear). Conidiogenous loci ring-like with a central pore, slightly thickened and darkened, apical at first and later displaced laterally. Conidia solitary, brown, coarsely verrucose, cylindrical to ellipsoidal, apex rounded, base truncate with a marginal frill and a dark conspicuous hilum, aseptate or septate, sometimes constricted at the septum; secession rhexolytic (adapted from Videira et al. 2017).

 Type species: Annellosympodia orbiculata McTaggart, R.G. Shivas & U. Braun

Notes: Annellosympodia is characterised by minute pulvinate sporodochia, and solitary, brown, coarsely verrucose, cylindrical to ellipsoidal conidia. There is no culture available for Annellosympodia and its phylogenetic position is uncertain. The placement of Annellosympodia in Mycosphaerellaceae is doubtful.
