中国海南异斑衣属Synarthonia(斑衣菌科、斑衣菌目)一新种OA
A new species of Synarthonia(Arthoniaceae,Arthoniales)from Hainan Province,tropical China
本研究根据形态学、化学及系统发育分析发现异斑衣属 Synarthonia 一新种——海南异斑衣 Synarthonia hainanensis,该种分布于中国海南省.其主要特征为地衣体白绿色;子囊果短线状至长线状,红棕色至黑色,无粉霜;子实层遇碘变红紫色;子囊顶环 K/I 无反应;子囊孢子透明,具4横隔,呈长卵圆形,大小为18-24.5×6.5-9.5 µm,顶端细胞增大.本文提供了该新种的分子数据、分类学描述、形态学和解剖学特征图片以及与相似物种区别的讨论.此外,本文提供了世界已知该属 25 种地衣的分种检索表.
Based on morphological,chemical,and phylogenetic analyses,a new species of the lichenized fungal genus Synarthonia,Synarthonia hainanensis,is described.This species is currently known only from Hainan Province.Synarthonia hainanensis is characterized by whitish-green thallus,short lirelliform to elongate,reddish-brown to black and epruinose ascomata,I+reddish-purple hymenium,K/I-blue distinct ocular chamber in the asci,hyaline,4-septate,and oblong-ovoid ascospores with the size of 18-24.5×6.5-9.5 µm.Molecular data,detailed taxonomic description,and images illustrating the morphological and anatomical characteristics of the new species are provided.A discussion on the differences between the new species and its similar species is also included.In addition,a key to 25 species of this genus is presented herein.
