Pseudovalsaria Spooner, Trans. Br. mycol. Soc. 86(3): 405 (1986)
MycoBank number: MB 25775; Index Fungorum number: IF 25775; Facesoffungi number: FoF 13014; 2 morphological species (Species Fungorum 2020), 1 species with sequence data.
Type species – Pseudovalsaria foedans (P. Karst.) Spooner
Notes – Spooner (1986) introduced Pseudovalsaria as a member of Trichosphaeriaceae, Barr (1994) transferred it to Clypeosphaeriaceae and Rappaz (1995) referred it to the Boliniaceae. Untereiner et al. (2013) provided sequence data for Pseudovalsaria ferruginea which was closely related to Apiorhynchostoma (Boliniaceae) (Fig. 6).
Figure 6 – Phylogram generated from maximum likelihood analysis based on combined LSU, ITS and tub2 sequence data of Boliniales. Related sequences are taken from Læssøe et al. (2013). Seventy-three strains are included in the combined analyses which comprised 2081 characters (867 characters for LSU, 561 characters for ITS, 653 characters for tub2) after alignment. Members of Diaporthales are used as outgroup taxa. Single gene analyses were also carried out and the phylogenies were similar in topology and clade stability. The best RAxML tree with a final likelihood value of -34809.341208 is presented. Estimated base frequencies were as follows: A = 0.209463, C = 0.298053, G = 0.289389, T = 0.203095; substitution rates AC = 1.086242, AG = 2.378803, AT = 1.369068, CG = 1.213916, CT = 6.024342, GT = 1.000000; gamma distribution shape parameter a = 0.567627. Bootstrap support values for ML greater than 60% are given near the nodes. Ex-type strains are in bold. The newly generated sequences are indicated in blue.
