Ten new species of Trypetheliaceae are described: Astrothelium bullatothallinum from Venezuela, which is close to A. aeneum but differs by the bullate thallus with a thick cortex, intermixed in a mosaic with the prothallus; A. cayennense from French Guiana, which is similar to A. flavomegaspermum but with a yellow pigment in the pseudostroma near the ostioles; A. diaphanocorticatum from Papua New Guinea, which has a bullate thallus with a thick hyaline cortex and 3-septate ascospores of 25–28×10–12 μm; A. macroeustomum from French Guiana, with joint lateral ostioles, UV+ yellow ostiolar region and 5-septate ascospores of 50–55×12–17 μm; A. minicecidiogenum from Costa Rica, with muriform ascospores of 70–90×20–25 μm, without pseudostromata, with solitary ascomata, lateral ostioles and an inspersed hamathecium; A. palaeoexostemmatis from Thailand, which is similar to A. exostemmatis but with larger, I+ blue ascospores; A. quasimamillanum from Brazil, with muriform ascospores of 30–33×9·5–10·5 μm, without pseudostromata, with solitary ascomata, lateral ostioles and an inspersed hamathecium; A. studerae from Brazil, with astrothelioid ascomata, lichexanthone only in the pseudostromata, 3-septate ascospores of 21·5–23·0×6·5–7·5 μm; A. tanianum from Malaysia, with a bullate thallus, solitary ascomata, covered by the thallus, (9–)11(–15)-septate ascospores, 75–100×20–22 μm; and Pseudopyrenula miniflavida from Brazil, with a yellow-inspersed hamathecium, the inspersion dissolving in KOH without colour change, and 3-septate ascospores, 15–17×5·5–6·5 μm. The unusually thick, hyaline cortical layer of the thallus of Astrothelium diaphanocorticatum, through which the individual algal cells are clearly visible, is discussed. Furthermore, 30 species are reported from 34 countries in which they had previously been unrecorded; one (Astrothelium inspersaeneum) is from a new continent, Asia.
