Data from: Morphological and phylogenetic evidences unveil a novel species of (Gyroporus) (Gyroporaceae, Boletales) from Indian Himalaya

Repeated macrofungal forays to East district of Sikkim followed by morphological and phylogenetic studies of collected wild mushrooms revealed an undescribed species, proposed here as <i>Gyroporus paramjitii</i>. This species is featured with hemispheric to plane dark brown to brownish orange pileus, concolorous or darker stipe, snow white to pale yellow pore surface which is immutable when bruised, 2- to 4-spored basidia, reniform to elliptic basidiospores, presence of pleurocystidia and cheilocystidia, absence of caulocystidia, trichoderm pattern of pileipellis and stipitipellis with encrusted erect hyphal elements and occurrence under <i>Castanopsis</i> sp. Macro- and micromorphological details coupled with phylogenetic analyses (based on nrITS and nrLSU data) are presented for this taxon.

对锡金东部地区开展多次大型真菌野外考察，并对采集到的野生蘑菇进行形态学与系统发育研究后，发现了一个尚未描述的新物种，本文将其拟定为*Gyroporus paramjitii*。该物种的形态特征如下：菌盖呈半球形至平展状，颜色为深棕色至棕橙色；菌柄与菌盖同色或颜色更深；菌孔面呈雪白色至淡黄色，受伤后无变色反应；担子具2~4个担孢子；担孢子呈肾形至椭圆形；存在侧囊体与缘囊体，无柄囊体；菌盖表皮与菌柄表皮为毛皮层构型，具被包裹物的直立菌丝组分；该物种生于锥属（*Castanopsis*）植物林下。本文针对该分类单元，提供了其宏观与微观形态学细节，并基于核糖体转录间隔区（nrITS）与核糖体大亚基（nrLSU）序列数据开展了系统发育分析。
