The Calliergon-Scorpidium-Drepanocladus complex is represented in Catalonia by Calliergon giganteum (Schimp.) Kindb., Straminergon stramineum (Brid.) Hedenäs, Scorpidium cossoni (Schimp.) Hedenäs, S. revolvens (Sw. ex Anonymo) Rubers, S. scorpioides (Hedw.) Limpr., Drepanocladus aduncus (Hedw.) Warnst., Sanionia uncinata (Hedw.) Loeske, Warnstorfia exannulata (B., S. & G.)

Ochyra. An identification key with all these taxa is provided. Calliergon cordifolium (Hedw.) Kindb. although not been found in Catalonian, appears in the key because has been reported from the Aragonese Pyrenees (next to the Catalan Pyrenees). For the present, Callialaria curvicaulis (Jur.) Ochyra and Drepanocladus sendtneri (Schimp. ex H. Müll.) Warnst. have not been collected in Spain, therefore they have to be excluded from the Spanish checklist.
