摘要利用mtSSU序列,采用贝叶斯和最大似然系统发育分析方法,对泡囊藻属的分子系统发育进行了研究。亚盘状囊瘤被判定为B的姐妹。citricola而不是B。leucoblepharum clade,B. subundulatum组(种间具紧密的柱头缘)是一个单系群,并描述了3个海南新记录种:B.褐盘草C. Wang & J.C. Wei,具深褐色的凹苞,囊壳中有结晶,并含有2,5,7-三氯-3-O-甲基去甲环己酮; B.红褐藓C. Wang & J.C. Wei,具红褐色的子囊盘,3-6隔子囊孢子,含5,7-二氯-3-O-甲基去甲环己酮; B.黑盘果木C. Wang & J.C. Wei,具有纯黑色的子囊盘,一个K+橄榄黑色的子囊盘,并存在托布津酸。
Abstract A molecular phylogeny of the genus Byssoloma is inferred from mtSSU sequences using Bayesian and maximum likelihood phylogenetic analyses. Byssoloma subdiscordans is resolved as sister to B. citricola rather than to the B. leucoblepharum clade, the B. subundulatum group (species with a compact apothecial margin) is shown to be a monophyletic group, and three species belonging to this group are described as new to science from Hainan Province in China: B. brunneodiscum W. C. Wang & J. C. Wei, with dark brown apothecia, crystals in the excipulum and the presence of 2,5,7-trichloro-3-O-methylnorlichexanthone; B. rubrofuscum W. C. Wang & J. C. Wei, with red-brown apothecia, 3–6-septate ascospores and the presence of 5,7-dichloro-3-O-methylnorlichexanthone; B. melanodiscocarpum W. C. Wang & J. C. Wei, with pure black apothecia, a K+ olive-black hypothecium and the presence of thiophanic acid.
