Spore classification in the genera bangia and porphyra

Abstract

Prior to the presentation by Drew (1956) of a system of classification for spores involved in the life histories of members of the Bangiophyceae, there was no uniform scheme. With the increased attention given to field and culture studies, particularly within the Bangiaceae, it is essential that a more comprehensive terminology be developed that considers experimental data on spore production. Drew’s definition of Type II spores is re-examined and a system of classification based on cell fate and ceil function as defined by studies on the photobiology of the Bangiaceae is proposed. © 1972 Taylor & Francis Group, LLC.
