红叶孔菌属（Erythrophylloporus）是一种新的牛肝菌属，具有红色层状膜托，根据形态学和多基因系统发育分析，属于牛肝菌科。 Erythrophylloporus cinnabarinus 被描述为一个新种，代表了该属的类型。从形态上看，朱砂的特征是担子体呈红橙色至黄红色，片层由红橙色至黄红色，碰伤时逐渐变为灰蓝色或灰绿松石色至灰绿色，鲜黄色背景略转为深紫色，暴露在空气中时由黑蓝色变为深蓝色，光滑且宽椭圆形，椭圆形至近卵圆形担子孢子，深黄色 棕色色素囊肿。基于内转录间隔区 (ITS) 和核糖体 RNA 大亚基 (nrLSU)、翻译延伸因子 1-α (tef1-α)、RNA 聚合酶 II 最大亚基 (rpb1) 和 RNA 聚合酶 II 第二大亚基 (rpb2) 组合序列的系统发育分析证实： Erythrophylloporus 是牛肝菌科中的一个独立属系。提供了详细的描述、线条图以及与表型相似属的比较。
Erythrophylloporus, a new bolete genus with a red‐colored lamellate hymenophore, is erected within the family Boletaceae based on morphology and multigene phylogenetic analyses. Erythrophylloporus cinnabarinus is described as a new species and represents the type of the genus. Morphologically, E. cinnabarinus is distinguished by a combination of reddish orange to yellowish red basidiomes, reddish orange to yellowish red lamellae gradually changing grayish blue or grayish turquoise to grayish green when bruised, vivid yellow context slightly turning dark violet, blackish blue to dark blue when exposed to air, smooth and broadly ellipsoid, ellipsoid to nearly ovoid basidiospores and dark yellowish brown pigmented cystidia. Phylogenetic analyses based on the internal transcribed spacer region (ITS) and the combined sequences of the large subunit nuclear ribosomal RNA (nrLSU), translation elongation factor 1‐alpha (tef1‐α), the largest subunit of RNA polymerase II (rpb1) and the second largest subunit of RNA polymerase II (rpb2) confirm that Erythrophylloporus is an independent generic lineage in the Boletaceae. A detailed description, line drawings and comparisons with phenotypic similar genera are provided.
