Taxonomic studies including morphological observations and phylogenetic analyses were conducted on Japanese “uragin-take”, an unidentified species from Amazonia, Brazil and their allies. Phylogenetic analyses using ITS, nrLSU and RPB2 regions revealed that “uragin-take”, Neofomitella polyzonata and the unidentified species formed a monophyletic clade separate from the clade including the other four Neofomitella spp. and that “uragin-take” is conspecific with N. polyzonata. Morphological investigations on authentic specimens revealed that Polyporus subradiatus is a prior name for N. polyzonata. We propose Hirticrusta gen. nov. typified by H. subradiata segregated from Neofomitella, and we erected H. amazonica sp. nov. for the unidentified species. Hirticrusta is characterized by annual to biennial and sessile basidiocarps, semicircular to dimidiate pileus, velutinous to tomentose hairs on pileus surface, buff to brown context with a crustose layer indicated by a dark brown line forming a longitudinal section below the superficial hairs, a trimitic hyphal system, crustose layer composed of parallel and densely arranged brown hyphae and cylindrical basidiospores. The new species, H. amazonica is distinguishable from other polypores by downy and long tomentum on the pileus surface (up to 20 mm thick), brown context with a dark brown layer below the tomentum and round pores (5–7/mm).

对日本“尿精”进行了分类学研究，包括形态学观察和系统发育分析。日本“尿精”是一种来自亚马逊，巴西及其盟友的未鉴定物种。使用ITS，nrLSU和RPB2区域进行的系统发育分析显示，“尿精”，多带新孢子虫和未鉴定物种形成了与包括其他四个新孢子菌的进化枝分开的单系进化枝。而“尿精摄取”与多带猪笼草是同种的。对真实标本的形态学研究表明，por多孔猪笼草（Polyporus subradiatus）是多带猪笼草的前身。我们提出Hirticrusta gen。十一月 以H.subradiata为代表从Neofomitella分离，我们竖立了H. amazonica sp.。十一月 对于未知物种。荨麻锈病的特征是一年生至两年生的无柄基底果皮，半圆形至半圆形的绒毛，绒毛表面为绒毛状至绒毛状，浅黄色至棕色，壳皮层由暗褐色的线表示，在浅层毛发下方形成了纵切面，三生菌丝系统中，壳层由平行且密集排列的棕色菌丝和圆柱形担子孢子组成。新的物种，H。amazonica与绒毛和绒毛在绒毛表面长绒毛（厚达20毫米），棕色背景，绒毛下面的暗棕色层和圆形孔（5-7 / mm）有别于其他多孔。
