在对巴西圣埃斯皮里托州的红海藻调查中，在潮间带或漂流物中采集到五种Peyssonnelia，它们是Borgesen的Peyssonnelia armorica（P.Crouan et H.Crouan）Weber-van博塞，Borgesenii Weber-van博塞（南大西洋第一个记录），P. boudouresquei Yoneshigue，P. capensis Montagne和P. inamoena Pilger。本文对叶状体的结构和生殖发育进行了详细的研究。生殖结构，早期受精后阶段，和果孢子体发育以前已经调查了只有少数Peyssonnelia种，本研究的目的是提高我们的知识属。
Abstract During a survey of red marine algae from Espirito Santo State, Brazil, five species of Peyssonnelia were collected in the intertidal zone or as drift material: Peyssonnelia armorica (P.Crouan et H.Crouan) Weber-van Bosse in Borgesen, P. borgesenii Weber-van Bosse in Borgesen (the first South Atlantic record), P. boudouresquei Yoneshigue, P. capensis Montagne, and P. inamoena Pilger. Detailed studies of thallus structure and reproductive development are presented. Reproductive structures, early postfertilization stages, and carposporophyte development have been investigated previously for only a few Peyssonnelia species; the present study aims to improve our knowledge of the genus.
