Notes: It seems that Claudopus depluens (Fr.) firstly mentioned for New Zealand by Colenso (1893) is identical with Cl. byssisedus (Fr.) described above. In spite of a thorough study no apparent differences were found between the microscopical and macroscopical characters of Claudopus byssisedus (Fr.) collected in Europe or North America (Hesler 1967: 16) and the material gathered in New Zealand.
