The taxonomy of the corticioid fungi from the class <i>Atractiellomycetes</i> (<i>Pucciniomycotina, Basidiomycetes</i>) currently addressed to the genus <i>Helicogloea,</i> is revised based on morphological and nuclear ribosomal DNA (ITS and LSU) data. The genus is restricted to 25 species with semitranslucent, gelatinous basidiocarps lacking differentiated cystidia and clamps on hyphae, of which 11 are described as new to science. The asexual genus <i>Leucogloea</i> is placed as a synonym of <i>Helicogloea s. str</i>. Since the type species of <i>Saccoblastia</i>, <i>S. ovispora</i>, is combined to <i>Helicogloea</i>, a new genus, <i>Saccosoma</i>, is introduced to encompass <i>Saccoblastia farinacea</i> and six related species, one of which is described as new. In contrast to <i>Helicogloea</i> in the strict sense, the basidiocarps of <i>Saccosoma</i> are arid, not gelatinized, and hyphae are clamped. The third lineage of the corticioid <i>Atractiellomycetes</i> is represented by the <i>Bourdotigloea vestita</i> complex. Species of <i>Bourdotigloea</i> are devoid of clamps but often possess well-differentiated cystidia, as well as long, cylindrical-fusiform basidiospores. <i>Bourdotigloea</i> encompasses nine species, of which six are described here as new.
