FIGURE 1. A in The lichen family Physciaceae in Thailand-II. Contributions to the genus Heterodermia sensu lato

FIGURE 1. A. Heterodermia pseudospeciosa, longitudinal section through thallus showing the periclinal hyphae of the upper cortex forming a prosoplectenchyma characterizing Heterodermia s.lat. (scale 20 µm). B. Physcia erumpens, longitudinal section through thallus showing the anticlinal hyphae of the upper cortex forming a paraplectenchyma, characteristic for Physcia s.lat. C. Leucodermia leucomelos f. albociliata, lobes dichotomously branched, ribbon-like with conspicuous long marginal rhizines. D. Polyblastidium subneglectum (Elix) Kalb, comb. nov., Mycobank MB 813851, Basionym: Heterodermia subneglecta Elix, Australas. Lichenol. 68: 17 (2011), lobes irregularly to sympodially branched, appressed to the substrate not or only slightly ascending towards the tips. E. Heterodermia galactophylla, tufts of apically ascending lobes with white marginal rhizines. F. Heterodermia comosa, thallus subfruticose, lobes affixed mainly near the base, with paddle-shaped tips and white cilia.
