从对大西洋森林和巴西亚马逊地区的实地考察和对植物标本室材料的修订中收集到的标本显示，存在无法归属于任何已描述物种的Trechispora标本。基于nuc rDNA ITS1-5.8 s - its2 （ITS）和nuc 28S rDNA （28S）区域的系统发育分析证实，这些标本属于2个新种，分别为Trechispora mollis和Trechispora torrendii。软体线虫有致密的水样膜膜膜，与尼维虫最相似，但与之不同的是，在膜下存在膨大的细胞。激流螺旋体的膜膜类似于粉孢螺旋体，但这两个物种在遗传上有很好的分离。提出了新组合，并报道了巴西地区和生物群系的新记录。描述，插图，一个关键的巴西种，T.刚性的第一个序列，并为该属的系统发育。
Collections from field expeditions to the Atlantic Forest and to Amazonia in Brazil and revision of herbarium material revealed the presence of Trechispora specimens that could not be assigned to any described species. Phylogenetic analysis based on nuc rDNA ITS1-5.8S-ITS2 (ITS) and nuc 28S rDNA (28S) regions confirmed that these specimens belong to two new species, here described as Trechispora mollis and Trechispora torrendii. Trechispora mollis has a densely hydnoid hymenophore and is most similar to T. nivea, but differs from it by the presence of inflated cells in the subiculum. Trechispora torrendii has a minutely grandinioid hymenophore similar to T. farinacea, but these two species are genetically well separated. The new combinations T. brasiliensis and T. mellina are proposed, and new records from Brazilian regions and biomes are reported. Descriptions, illustrations, a key to Brazilian species of Trechispora, the first sequence of T. rigida, and a phylogeny for the genus are presented.
