Diversity of green algae (Chlorophyta) from bromeliad phytotelmata in areas of rocky outcrops and "restinga", Bahia state, Brazil

Abstract A floristic survey for green algae (Chlorophyta) from bromeliad phytotelmata of areas of rocky outcrop (Serra da Jibóia) and "restinga" (Parque das Dunas), Bahia state, Brazil is presented here. A total of twenty-three taxa were identified, including three species (Asterococcus superbus, Gongrosira papuasica and Lagerhemia chodatti) that are newly reported for Brazil and two Oedogonium species (Oedogonium pulchrum and O. areschougii) that were recollected in Brazilian territory after 115 years.

摘要 本研究针对巴西巴伊亚州岩石裸露地（希博伊拉山Serra da Jibóia）与滨海砂质植被（restinga）分布区的杜纳斯公园（Parque das Dunas）内凤梨科植物的积水附生小生境（phytotelmata）开展绿藻（绿藻门Chlorophyta）的区系调查。本研究共鉴定出23个分类群，其中3个物种（华丽星球藻Asterococcus superbus、巴布亚胶毛藻Gongrosira papuasica、乔达蒂 Lagerhemia chodatti）为巴西新记录种；另有2种鞘藻属（Oedogonium）物种——美丽鞘藻（Oedogonium pulchrum）与阿尔榭鞘藻（O. areschougii）——在时隔115年后于巴西境内被重新采集到。
