Two epiphytic Leptogium species from East Africa, both with transversely septate ascospores, are here describedas new. They produce plicate thalli and have a paraplectenchymatous proper exciple and a one cell layer thick cortex on thethalline exciple. Leptogium bellum has so far only been collected from Mt. Kilimanjaro, Tanzania, where it occurs from midmontaneforests up to the subalpine zone. Leptogium tiinae occurs in relatively open habitats at lower elevations, with thetype specimen collected from the Taita Hills, Kenya. Additionally, details from a Leptogium chloromeloides isotype and a keyfor Leptogium species with transversely septate ascospores are provided.
