Amanita pseudorufobrunnescens is described as a new species in the subgenus Amanitina section Amidella of family Amanitaceae from north-western Himalaya, India. Distinct morphological characters, odour and molecular phylogenetic analysis based on the large subunit of nuclear ribosomal DNA (nrLSU) data revealed that the present species differs from other members of sect. Amidella. This species is characterised by its whitish basidiomata that turn brownish orange with age, its whitish to cinnamon brown, floccose to radially fibrillose universal veil remnants on the pileus, its close lamellae becoming brownish orange on exposure, its elongate basidiospores and its association with Quercus oblongata (syn. Q. leucotrichophora). A detailed morphological description, line drawings, colour photographs and Maximum Likelihood (ML) phylogenetic placement of the new species are provided.

来自印度喜马拉雅山的伞形毒蕈科新种伞形毒蕈

鹅膏pseudorufobrunnescens被描述为在亚属的一个新种Amanitina部分Amidella从西北部的喜马拉雅，印度家庭捕蝇蕈的。基于核糖体DNA（nrLSU）数据大亚基的独特形态特征，气味和分子系统发育分析表明，该物种不同于该教派的其他成员。阿米德拉。该物种的特征是其白色的basidiomata随着年龄的增长而变成棕橙色，从白色变成肉桂棕色，绒毛上的絮状到放射状原纤维残留的普遍面纱，暴露时其紧密的薄片变成棕橙色，其细长的担子孢子以及与长白栎的结合（同步Q.leucotrichophora）。提供了新物种的详细形态描述，线条图，彩色照片和最大似然（ML）系统发生位置。
