ABSTRACT. A collection of Lower Cretaceous mosses from the Khasurty, Transbaikalia, South Siberia includes numerous compressions of the moss Bryokhutuliinia obtusifolia sp. n., and also specimens referred to Palaeodichelyma sinitzae and Tricostium longifolium sp. n. Preservation allows clear views of leaf areolation in these species. Three more species with strong costae are likely acrocarpous, but due to an unclear view of the cell structure they are described as Muscites sp. 1, sp. 2 and sp. 3.
