Data from: Hymenophyllum subg. Hymenophyllum (Hymenophyllaceae) in the Brazilian Atlantic forest
<p>A revision of the species of <i>Hymenophyllum </i>subg. <i>Hymenophyllum</i> in the Brazilian Atlantic forest domain is presented. Morphological and molecular analyses were performed, based on herbarium material and samples collected during fieldwork. For the molecular analyses, data of the plastidial markers <i>rbcL</i>, <i>rbcL-accD</i>, <i>rps4-trnS</i> and <i>trnG-trnR </i>were used. The analyses demonstrated the existence of three distinct and independent lineages of subgenus <i>Hymenophyllum</i> in Atlantic forest domain. Three taxa were recognized: <i>H. fucoides</i>, <i>H. megachilum</i>, and an additional new species, <i>H. bradeanum</i>, a narrow endemic to the Itatiaia Massif, southeastern Brazil. Distribution maps, identification keys, descriptions and illustrations are present, together with an update of the conservation status of the species.</p>
