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 Gyroporus paramjitii. 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 Castanopsis sp. Macro- and micromorphological details coupled with phylogenetic analyses (based on nrITS and nrLSU data) are presented for this taxon.

研究人员多次赴锡金东部地区开展大型真菌野外调查（macrofungal forays），并对采集到的野生蘑菇进行形态学与系统发育研究，最终发现了一个未被描述的新物种，本文将其拟定为圆孔牛肝菌属新种Gyroporus paramjitii。该物种具有如下形态特征：菌盖（pileus）呈半球形至平展状，颜色为暗棕色至棕橙色；菌柄（stipe）与菌盖同色或颜色更深；菌孔面（pore surface）呈雪白色至淡黄色，受伤后不会变色；担子（basidia）具2-4个孢子；担孢子（basidiospores）呈肾形至椭圆形；存在侧囊体（pleurocystidia）与缘囊体（cheilocystidia），无柄囊体（caulocystidia）；菌盖表皮（pileipellis）与菌柄表皮（stipitipellis）均为毛皮层型（trichoderm pattern），具内含物包被的直立菌丝（erect hyphal elements）；该物种生于栲属（Castanopsis）植物林下。本文还提供了该分类群（taxon）的宏观与微观形态学细节，以及基于核核糖体内转录间隔区（nrITS）和核核糖体大亚基（nrLSU）序列数据的系统发育分析结果。
