Abstract

Five new species of corticolous pyrenocarpous lichens are described from tropical and subtropical forests in the Chaco and Misiones provinces in NE Argentina: Aspidothelium submuriforme with globose, grey ascomata and ascospores mostly 7-septate with 0–2 oblique longitudinal septa, 25–28×8–10 µm; Pyrenula inspersoleucotrypa, characterized by a thallus without pseudocyphellae, aggregated ascomata, an inspersed hamathecium, and ascospores of 17–20×6·5–8·0 µm with diamond-shaped lumina; Pyrenula punctoleucotrypa, which has a thallus with pseudocyphellae, aggregated ascomata in a conical pseudostroma, with fused ostioles, not inspersed hamathecium, and ascospores of 10–12×4–5 µm with rounded lumina; Strigula muriconidiata, containing immersed pycnidia with hyaline, densely muriform, ellipsoid conidia, 90–103×32–35 µm; Trypethelium globolucidum, forming sessile pseudostromata with black and whitish parts, an inspersed hamathecium, ascospores 13–19-septate, (65–)83–97×11·5–14·5 µm, lumina rounded to lentiform and containing lichexanthone.
