Bertia De Not., Gior. Bot. Ital. 1(1): 334 (1844)
MycoBank number: MB 551; Index Fungorum number: IF 551; Facesoffungi number: FoF 01366; 32 morphological species (Species Fungorum 2020), 9 species with sequence data.
Type species – Bertia moriformis (Tode) De Not.
Notes – The type species, Bertia moriformis, is characterized by tuberculate ascomata and clavate asci and brown ascospores (Mugambi & Huhndorf 2010, Maharachchikumbura et al. 2016b). We provide a multi-gene phylogenetic tree (Fig. 11), which reveals that Bertia is closely related to members of Nitschkiaceae (Nitschkia, Acanthonitschkea and Fracchiaea) with good support (Fig. 11).
Figure 11 – Phylogram generated from maximum likelihood analysis based on combined LSU, tef1 and ITS sequence data for Coronophorales. Related sequences are referred to Hongsanan et al. (2017). Seventy-nine strains are included in the combined analyses which comprised 2211 characters (1044 characters for LSU, 627 characters for tef1, 540 characters for ITS) after alignment. Members of Torpedosporales are used as outgroup taxa. Single gene analyses were carried out and the phylogenies were similar in topology and clade stability. The best RaxML tree with a final likelihood value of -23354.525618 is presented. Estimated base frequencies were as follows: A = 0.228019, C = 0.288494, G = 0.281955, T = 0.201533; substitution rates AC = 1.194725, AG = 2.787601, AT = 1.703067, CG = 0.955075, CT = 3.781057, GT = 1.000000; gamma distribution shape parameter a = 0.736138. Bootstrap support values for ML greater than 50% are given near the nodes. Ex-type strains are in bold. The newly generated sequences are indicated in blue.
