The poroid species of Auriculariales have been placed in Aporpium, Elmerina, Protodaedalea and Protomerulius and include resupinate, effused-reflexed or pileate basidiomata, 4-celled basidia and globose, ovoid to allantoid basidiospores. According to recent DNA-based phylogenetic studies, those genera have good support in Auriculariales, but many species without phylogenetic treatment remain in uncertain taxonomic position, especially from the Neotropics. In the present paper, specimens with poroid hymenophore and septate basidia were collected in Brazil and morphological and DNA analyses, based in ITS and LSU regions, evidenced three new species (Elmerina brasiliensis, E. santanaensis and Protomerulis pedratalhadensis) and three new combinations (E. minipora, E. strigosa and E. obtusispora). Descriptions and illustrations of the new species, the new combinations and a comparative table of species of the genera are provided.

Elmerina 和 Protomerulius:来自巴西的基于形态和分子分析的新产品

木耳目中的孔状物种已被归入AporpiumElmerinaProtodaedaleaProtomerulius中,包括反旋、溢出反射或绒毛担子、4 细胞担子和球形、卵圆形到尿囊状担子孢子。根据最近基于DNA的系统发育研究,这些属在木耳目中得到了很好的支持,但许多未经系统发育处理的物种仍然处于不确定的分类地位,特别是来自新热带地区。在本文中,在巴西收集了具有孔状膜托和隔膜担子的标本,并在 ITS 和 LSU 地区进行了形态学和 DNA 分析,证实了 3 个新种(Elmerina brasiliensis、E. santanaensisProtomerulis pedratalhadensis)和 3 个新组合(E )。 . 小孔菌E. strigosaE. obtusispora )。提供了新物种、新组合的描述和插图以及各属物种的比较表。
