【摘要】 通过对地卷属地衣形态和化学的研究,并结合核基因ITS序列的系统发育分析,报道了采自中国西北地区地卷属的1个中国新记录种——芽片地卷(新拟)。它的典型特征是沿着地衣体边缘或地衣体上表面裂隙具有大量的薄片状phyllidia,且常常覆有粉霜。地衣体上表面的边缘具有白色绒毛,下表面具有丛生假根,而且假根在边缘为白色,逐渐向中心变为深色。该研究提供了该种的详细描述,并与近缘种进行了细致的讨论。更多还原

【Abstract】 A new record species Peltigera monticola Vitik.was identified from the northwest of China,based on morphological and chemical analysis,and a phylgenetic analysis of nrDNA ITS sequence was also carried out.It was distinguished by its numerous laminal phyllidia,often pruinose,along the margin or cracks,marginal parts tomentose,tufted rhizomes with pale near margins and darkened towards center.Detailed description and discussion with allied species were provided.更多还原
