Ballantine D.L.和Ruiz H. 2010.产于加勒比海波多黎各的两个深水Peyssonnelia新种：Peyssonnelia iridescens和Peyssonnelia gigaspora（Peyssonneliaceae，红藻门）。Phycologia 49：537-544. DOI：10.2216/09-88.1描述了两种新的独特的Peyssonnelia物种，来自波多黎各西南部的深水栖息地。Peyssonnelia iridescens具有独特的蓝色彩虹色条纹，形成松散附着的叶片，直径可达6.0厘米。壳具有Peyssonnelia atropurpurea型植物组织。四孢子囊从顶端周叶细胞的远端切下，尺寸可达53 µm宽× 135 µm长。果孢子囊的最大尺寸为25-30 µm，形成于细长的线虫中。巨孢培氏菌（Peyssonnelia gigaspora）为多种颜色，棕褐色至红色，生活时有明显的放射状条纹和红色斑点。结壳紧贴底层，厚度通常可达130微米，但偶尔也有200微米厚，并具有Peyssonnelia rubra型的植物组织。四孢子囊是卵形的，非常大，可达100 µm宽× 250 µm长，并与近端的侧旁细胞分化，因此位于中间位置。
Ballantine D.L. and Ruiz H. 2010. Two new deepwater Peyssonnelia species, Peyssonnelia iridescens and Peyssonnelia gigaspora (Peyssonneliaceae, Rhodophyta) from Puerto Rico, Caribbean Sea. Phycologia 49: 537–544. DOI: 10.2216/09-88.1 Two new distinctive Peyssonnelia species are described from deepwater habitats in southwestern Puerto Rico. Peyssonnelia iridescens possesses a distinctive bluish iridescent fringe and forms loosely adherent blades up to 6.0 cm across. The crusts possess a Peyssonnelia atropurpurea-type vegetative organization. Tetrasporangia are cut off distally from apical perithallial cells and measure up to 53 µm wide × 135 µm long. Carposporangia measure 25–30 µm in their largest dimension and are formed in elongate nemathecia. Peyssonnelia gigaspora is variously coloured, tan to reddish, with obvious radial striations and reddish spots when living. The crusts are closely appressed to the substratum and normally measure up to 130 µm in thickness, but are occasionally 200 µm thick and possess the Peyssonnelia rubra-type vegetative organization. Tetrasporangia are ovate and extremely large, measuring up to 100 µm wide × 250 µm long, and differentiate from the proximal paraphysal cell, thus being situated in an intercalary position.
