Pseudopassalora
Pseudopassalora Crous, in Crous et al., Persoonia 27: 41 (2011).
Index Fungorum number: IF 560570; Facesoffungi number: FoF 08083, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on leaves. Sexual morph: Unknown. Asexual morph: Mycelium consisting of smooth, hyaline, septate, branched hyphae. Conidiophores solitary on hyphae, micronematous, reduced to conidiogenous loci, or erect, cylindrical, straight to flexuous, hyaline, smooth, 1–2-septate. Conidiogenous cells integrated, reduced to loci on hyphae, or terminal on short conidiophores, cylindrical, hyaline, smooth, containing a solitary terminal, truncate locus, or at times polyblastic with 1–3 phialidic loci that are thickened along the rim. Conidia solitary, fusoid-ellipsoidal, brown, verruculose to warty, widest in the middle of the upper third, tapering to a subobtuse apex, aseptate or medianly uniseptate; base truncate, at times slightly thickened along the rim (adapted from Crous et al. 2011).
Type species: Pseudopassalora gouriqua Crous
Notes: Pseudopassalora is characterised by branched hyphae, solitary, erect hyaline conidiophores, polyblastic with 1–3 phialidic loci conidiogenous cells, and solitary, fusoid-ellipsoidal, brown conidia. Pseudopassalora resembles Passalora in having slightly thickened loci, but is distinct in having hyaline hyphae and conidiogenous cells, and conidia that become warty when mature. Pseudopassalora also resembles Retroconis, but differs in producing solitary conidia (Seifert et al. 2011). The placement of Pseudopassalora is uncertain and is currently in Pleosporales genera incertae sedis. Molecular markers available for Pseudopassalora are ITS and LSU.
