One new genus, Meiotheciella, and one new variety, Acroporium microcla
don var. rhizogemmae, are described for the Australian Sematophyllacea
e. Seven new combinations are proposed (Rhaphidorrhynchium amoenum var
. congruens, Sematophyllum subhumile var. contiguum, Trichosteleum sap
roxylophilum, Trichosteleum subfalcatulum, Trichosteleum wattsii, Warb
urgiella leucocyta and Warburgiella macrospora). In addition, nine new
synonyms are suggested. The reports of Clastobryum conspicuum, Semato
phyllum crassiusculum, Sematophyllum saproxylophilum and Rhaphidorrhyn
chium subcylindricum from Australia are dismissed.
