根据DNA数据和形态学证据，对原斑壳属（Protomerulius）和异毛壳属（Heterochaetella）的分类进行了修订，并将其模式种巴西原斑壳属（P. brasiliensis）和异毛壳属（H. dubia，被证明是同源的。因此，H. dubia和相关的物种，其中四个被描述为新的，被放置在Protomerulius。Heterochaete microspora也结合在Protomerulius，属的概念被重新定义为包括渗出的物种与光滑或多刺的处女膜和单丝菌丝结构。多刺裸毛藻（Psilochaete multifora，gen. and spec. nov.）在挪威发现的Heterochaetella cystidiophora在巴西被重新收集，并被置于Heterochaete sanctae-catharinae的同义词中。本种不属于原小刺壳属-异毛壳属谱系，它被转移到Metulochaete，gen. nov.。
The taxonomy of Protomerulius and Heterochaetella is revised based on DNA data and morphological evidence, and their type species, P. brasiliensis and H. dubia, are proved to be congeneric. As a consequence, H. dubia and related species, of which four are described as new, are placed in Protomerulius. Heterochaete microspora is also combined in Protomerulius, and the genus concept is redefined to encompass effused species with smooth or spiny hymenophore and monomitic hyphal structure. Psilochaete multifora, gen. and spec. nov. is a distant relative of Protomerulius spp. found in Norway. Heterochaetella cystidiophora is re-collected in Brazil and placed in the synonyms of Heterochaete sanctae-catharinae. This species does not belong to the Protomerulius-Heterochaetella lineage, and it is transferred to Metulochaete, gen. nov.
