Trichocytes in Lithophyllum kotschyanum and Lithophyllum spp. (Corallinales, Rhodophyta) from the NW Indian Ocean / D. Basso, A. Caragnano, G. Rodondi. - In: JOURNAL OF PHYCOLOGY. - ISSN 0022-3646. - 50:4(2014), pp. 711-717. [10.1111/jpy.12197]
Abstract:
The current diagnosis of the genus Lithophyllum includes absent or rare trichocyte occurrence. After examining holotype material, single trichocytes have been revealed to occur abundantly in Lithophyllum kotschyanum Unger, and in freshly collected specimens of Lithophyllum spp. from the Red Sea, Gulf of Aden and Socotra Island (Yemen). Trichocyte occurrence is not considered a diagnostic character at specific or supraspecific levels in the Lithophylloideae, and the ecological significance of trichocyte formation is discussed. The generitype species, L. incrustans Philippi, does not show trichocytes nor do many other Lithophyllum species from diverse geographic localities, but the presence of abundant trichocytes in other congeneric taxa requires emendation of the genus diagnosis. Therefore, the diagnosis of Lithophyllum is here emended by eliminating the adjective "rare" in the sentence concerning trichocyte occurrence, as follows: "Trichocytes present or absent, if present occurring singly.
