Pararamichloridiaceae Crous, Persoonia 39: 357 (2017)
MycoBank number: MB 823463; Index Fungorum number: IF 823463; Facesoffungi number: FoF 05314; 3 species.
Pathogenic on plant leaves. Sexual morph: Undetermined. Asexual morph: Mycelium consisting of hyaline, smooth, septate, branched, hyphae. Conidiophores erect, solitary, straight to flexuous, septate, branched at apex or not, subcylindrical, subhyaline to medium brown, smooth. Conidiogenous cells terminal and intercalary, subcylindrical, subhyaline to medium brown, smooth, polyblastic, denticulate. Conidia solitary, hyaline, smooth, aseptate, thin-walled, clavate to ellipsoid (adapted from Crous et al. 2017a).
Type genus – Pararamichloridium Crous
Notes – Crous et al. (2017a) introduced Pararamichloridiaceae and accepted Pararamichloridium and Woswasia. However, Woswasia, along with Xylochrysis and Cyanoannulus, was placed in Diaporthomycetidae families incertae sedis by Zhang et al. (2017a) based on morphology, phylogenetic analysis and molecular dating. In the multi-loci ITS, LSU, SSU and rpb2 phylogenetic tree, Pararamichloridium livistonae (CBS 143166) and P. verrucosum (CBS 128.86) grouped together and formed a separate clade with 99% MP bootstrap support, 92% ML bootstrap support and 100% Bayesian posterior probabilities (data not shown). Woswasia atropurpurea (CBS 133167), Xylochrysis lucida (CBS 135996) and Cyanoannulus petersenii (R044a and R044b) formed a separate branch which is distant from Pararamichloridium clade (data not shown). In this study, we exclude Woswasia from Pararamichloridiaceae based on its close phylogenetic affinity with Xylochrysis and Cyanoannulus in Woswasiaceae.
