Abstract:
Many species of Amanita sect. Phalloideae (Fr.) Quél. cause death of people after consumption around the world. Amanita albolimbata, a new species of A. sect. Phalloideae from Benin, is described here. The taxon represents the first lethal species of A. sect. Phalloideae known from Benin. Morphology and molecular phylogenetic analyses based on five genes (ITS, nrLSU, rpb2, tef1-α, and β-tubulin) revealed that A. albolimbata is a distinct species. The species is characterized by its smooth, white pileus sometimes covered by a patchy volval remnant, a bulbous stipe with a white limbate volva, broadly ellipsoid to ellipsoid, amyloid basidiospores, and abundant inflated cells in the volva. Screening for the most notorious toxins by liquid chromatography-high-resolution mass spectrometry revealed the presence of α-amanitin, β-amanitin, and phallacidin in A. albolimbata.
摘要:
Amanita教派的许多物种。Phalloideae(Fr.)奎尔。在世界各地消费后导致人们死亡。阿伯利巴塔天鹅尼塔,A.教派的一个新物种.来自贝宁的Phalloideae,在这里描述。分类单元代表A.sect的第一个致命物种。从贝宁已知的phalloideae。基于五个基因的形态学和分子系统发育分析(ITS,nrLSU,rpb2,tef1-α,和β-微管蛋白)揭示了A.albolimbata是一个独特的物种。该物种的特点是光滑,有时被斑驳的体积残留物覆盖的白色比目鱼,球形柄,白色边缘体积,宽椭圆体到椭圆体,淀粉样担子孢子,Volva中大量膨胀的细胞。通过液相色谱-高分辨率质谱法筛选最臭名昭著的毒素,发现存在α-amanitin,β-amanitin,和方黄中的石灰岩。
