Resumen
Las Rhizogoniaceae en las regiones Fueguina y Patagónica están representadas por cuatro taxa: Goniobryum subbasilare, Pyrrhobryum mnioides, Leptotheca gaudichaudii y Rhizogonium novae-hollandiae. Dado que en estas áreas sólo se conocen esporófitos de las dos primeras especies intentamos distinguirlas por medio de caracteres vegetativos. Con ese objetivo, se presenta una clave y notas taxonómicas y ecológicas adecuadas. Además presentamos y describimos las ornamentaciones esporales de las dos especies que fructifican. Por fin, citamos algunos nuevos sinónimos y determinaciones erradas, halladas en el curso de este estudio, que decidieron la exclusión de Rhizogonium lindigii (Hamp.) Mitt. y Pyrrhobryum breviofolium (Broth.) Manuel del área.
In Fuegian and Patagonian regions the Rhizogoniaceae are represented by 4 species, e.g. Goniobryum subbasilare, Pyrrhobryum mnioides, Leptotheca gaudichaudii and Rhizogonium novae-hollandiae. Due to the fact that in this area sporophytes are only known for the two former species, a definition of the four taxa based on vegetative characters is presented. A key to species, together with appropriate taxonomic and ecological notes, aid in the identification. SEM spores ornamentation of the two fruiting species are figured and described. A few new synonyms and various missidentifications are also discussed. These last resulted in Rhizogonium lindigii (Hamp.) Mitt. and Pyrrhobryum brevifolium (Broth.) Manuel, being excluded from the area.
