A new combination, Pseudocrossidium adustum, is proposed for Desmatodon adustus, an Australian taxon treated in the literature as conspecific with P. hornschuchianum. The range of this species is extended to South Africa. The species is described, lectotypified, illustrated and its distribution is mapped. Diagnostic characters and distinction from P. chilense and P. hornschuchianum are given. A key to Pseudocrossidium for Australia and South Africa is provided.
