Abstract
Two epiphytic Leptogium species from East Africa, both with transversely septate ascospores, are here described as new. They produce plicate thalli and have a paraplectenchymatous proper exciple and a one cell layer thick cortex on the thalline exciple. Leptogium bellum has so far only been collected from Mt. Kilimanjaro, Tanzania, where it occurs from mid-montane forests up to the subalpine zone. Leptogium tiinae occurs in relatively open habitats at lower elevations, with the type specimen collected from the Taita Hills, Kenya. Additionally, details from a Leptogium chloromeloides isotype and a key for Leptogium species with transversely septate ascospores are provided. [ABSTRACT FROM AUTHOR]
