Habitus of one year old, representative, cultured fungal strains belonging to Dothideomycetes and included in the phylogenetic analysis of Fig. 3. Anatomical structures were photographed from squashed sections mounted in water. Samples are reported with their number and the clade to which they belong as in Fig. 3. A1-A5) A537 (Phoma) – A1, A2 habitus of the mycelium; A3-A5 hyaline hyphae with inclusions forming a dense aggregate. B1-B3) A542 (Phoma) – B1, B2 habitus of the mycelium, B3 dense aggregate of hyphae. C1-C5) A930 (Lichenostigmatales) – C1, C2 habitus of the mycelium; C3-C5 yeast-like melanised cells forming dense aggregates. D1-D6) A931 (clade sister to Lichenotheliales) – D1, D2 habitus of the mycelium; D3-D6 plectenchymatous structure of hyaline hyphae with cylindrical cells, round cells as buds at the apexes of the hyphae (arrows). E1-E3) A 567 (clade sister to Lichenotheliales) – E1 habitus of the mycelium; E2, E3 melanized hyphae composed by elliptical and subcylindrical cells constricted at the septa, laterally budding. F1-F4) A554 (Myriangiales) – F1, F2 habitus of the mycelium; F3, F4 thin, hyaline hyphae. G1-G6) A559 (Teratospaheriaceae I) – G1, G2 habitus of the mycelium; G3-G6 melanized hyphae, branching and composed by cylindrical to subglobose cells. H1-H6) A960 (clade nested in Teratosphaeriaceae) H1, H2 habitus of the mycelium, hyphae develop inside the growth medium; H3-H6 melanized hyphae, branching and composed by cylindrical to subglobose cells. Scale bars =4 mm (A1, C1, D1, E1, F1, G1), 3 mm (B1), 2 mm (B2, H1), 1.5 mm (C2), 1 mm (A2, D2, F2, G2), 0.4 mm (H2), 50 μm (G3), 40 μm (C3, D3), 20 μm (A3, C5, E2, E3, F3, G4, H3-H6), 10 μm (A5, B3, D4-D6, F4, G5, G6)
