Mangifericomes E. F. Yang & Tibpromma, 2022

Notes.

Mangifericomes was established by Yang et al. (2022) as a monotypic genus in the Pleosporales genera incertae sedis to accommodate M. hongheensis E. F. Yang and Tibpromma as type species, which was isolated from Mangifera indica L. in China. Mangifericomes is characterized by immersed or semi-immersed, globose to subglobose, dark brown to black ascomata with or without ostioles; a hamathecium comprising filiform, hyaline, septate, branched cellular pseudoparaphyses (sensu Liew et al. 2000); 8 - spored, bitunicate, cylindrical-clavate, pedicellate asci; and ellipsoid, muriform, pale brown to brown ascospores, wrapped in a gelatinous sheath ( Yang et al. 2022). The updated phylogenetic tree of Mangifericomes is shown in Fig. 5 .

Figure 5. Phylogram generated from ML analysis of Pleosporales based on combined LSU, ITS, SSU, tef 1 - α, and rpb 2 sequence data of 159 taxa, which comprised 4584 base pairs of LSU = 1201, ITS = 534, SSU = 1018, rpb 2 = 930, tef 1 - α = 901. The best-scoring RAxML tree with a final likelihood value of - 91408.743991 is presented. The matrix had 3121 distinct alignment patterns, with 41.32 % of undetermined characters or gaps. Estimated base frequencies were as follows: A = 0.246701, C = 0.244302, G = 0.274425, T = 0.234571; substitution rates: AC = 1.391138, AG = 3.919388, AT = 1.582417, CG = 1.094328, CT = 7.887132, GT = 1.0; gamma distribution shape parameter α = 0.418663. Bootstrap support values for maximum likelihood (ML) equal to or greater than 70 % and clade credibility values greater than 0.90 from Bayesian inference analysis are labelled at each node. The tree is rooted with Orbilia auricolor (AFTOL-ID 906) and O. vinosa (AFTOL-ID 905). The new isolates are indicated in red, and the ex-type strains are in bold.
