 Remarks:This new species is similar to Thelotrema similans but differs consistently in the larger ascospores. Material of T. similans from Japan is described as having ascospores up to 100 ´ 30 µm; our own investigation of the lectotype in S revealed a size range of 70–120 ´ 20–30 µm. A specimen from Indonesia collected by Hale had ascospores up to 190 µm long and thus fits into the concept of the new species here. Both species share the corticate thallus and weakly amyloid ascospores (not ecorticate and non-amyloid as described by Matsumoto 2000). Otherwise most similar is T. lepadinum, which has much larger, prominent to sessile apothecia and ascospores in numbers of 1–4 per ascus. The new species should not be confused with the superficially similar, European T. macrosporum P. M. Jørg. & P. James. That species has a different ascospore type with more or less equal septa and thin outer wall, and the ascospores soon become brown; the ascospores are also relatively broader (3–4 times as long as broad versus 4–6 times in T. pseudosimilans). In addition, its apothecia have a relatively wider pore and the thallus cortex is less well-developed.
