(18) In-situ image of the holotype specimen. Scale bar = 2 cm. (19) Habit of the holotype specimen. Scale bar = 2 cm. (20) Radial section of a free margin showing frequently produced unicellular rhizoids (arrows) penetrating the thick hypobasal cuticle. Scale bar = 100 μm. (21) Section showing secondary pit connections (arrowhead) and cell fusions (arrow) in the lower perithallus, as well as the rapid decrease in cell size around the mid-perithallus. Scale bar = 100 μm. (22) Well-developed epithallus with frequently branching filaments whose cells are commonly pit connected (arrowhead) or fused (arrow) with those of adjacent filaments. Scale bar = 100 μm. (23) Radial-vertical section of the thick crust with well-developed epithallus lacking hair bases or trichocytes. Scale bar = 100 μm.
