Studies on Chinese species of Gelidiella and Pterocladiella (Gelidiales, Rhodophyta)

A detailed study of materials from our herbarium shows the presence of two species of Gelidiella and three species of Pterocladiella, including two new records and a new species. Previously recorded species include G. acerosaand P. capillacea. G. bornetii and P. caerulescensare new records for China and P. yinggehaiensisis believed to be a new species. This new species is characterized by its small thalli, 1.5–2 cm high, that are more densely branched on the middle to upper parts for one half their lengths. These characteristics are so distinctive that they can be used to separate this species readily from other species now reported in this genus.
