Abstract

A revision of the Australasian (Australian and New Zealand) species of Dicranoloma (Renauld) Renauld is presented. Fifteen species are accepted: Dicranoloma austroscoparium (Müll.Hal. ex Broth.) Watts & Whitel., D. billarderi (Brid. ex anon.) Paris, D. braunii (Müll.Hal. ex Bosch & Sande Lac.) Paris, D. daymannianum E.B. Bartram, D. diaphanoneuron (Hampe & Müll.Hal.) Paris, D. dicarpum (Nees) Paris, D. eucamptodontoides (Broth. & Geh.) Paris, D. fasciatum (Hedw.) Paris, D. leichhardtii (Hampe) Watts & Whitel., D. menziesii (Taylor) Renauld, D. obesifolium (R.Br.bis) Broth., D. platycaulon Dixon, D. plurisetum Dixon, D. robustum (Hook.f. & Wilson) Paris and D. trichopodum (Mitt.) Broth. Fifteen new synonymies were made. New lectotypifications have been made where necessary. Thirteen species occur in Australia and 10 in New Zealand. D. austroscoparium, D. diaphanoneuron and D. leichhardtii are endemic to Australia, while D. plurisetum and D. obesifolium are endemic to New Zealand. Moreover, D. platycaulon, D. fasciatum and D. trichopodum are endemic to the region. D. daymannianum and D. fasciatum are newly reported from Australia. All recognised species are described and illustrated and distribution maps and a key to the species have been provided.
