Leptopterigynandrum austro-alpinum looks very much like Pseudoleskeella tectorum-- a small pleurocarp growing on rocks with quite small leaves and a short and forked costa. Leptopterigynandrum austro-alpinum are nearly julaceous when dry, compared to P. tectorum which has a more chained appearance. The leaf cells of Leptopterigynandrum austro-alpinum are 2-3 to 1 in length rather than the shorter 1-2 to 1 leaf cells of P. tectorum. There are foliose pseudoparaphyllia present in Leptopterigynandrum austro-alpinum, though they can be difficult to spot. Leptopterigynandrum austro-alpinum has roughened, micropapillose laminal cell walls, though this is difficult to appreciate at any magnification less than 400:1. Leptopterigynandrum austro-alpinum is found at middle to upper elevation in rocky crevices.
