A report of two novel cyanobacterial species from Aphanocapsa for flora of Iran

In summer 2013، phytobenthos and periphyton cyanobacterial samples were collected from Sirch hot springs which are located in 50 Km of southeast of Kerman city (Iran) with coordinates of 30° 09´ 44˝ N and 57° 35´ 50. 0˝ E (Fig. 1A). Aphanocapsa rivularis، A. delicatissima are new species for Iran flora. The species of Aphanocapsa genera which have been reported previously from Iran are: Aphanocapsa grevillei (Berkeley) Rabenhorst by Faghir & Shafii (2013)، Soltani et al. (2012); A. incerta (Lemmermann) G. Cronberg & Komárek by Ramezanpoor (2004); and A. crassa Ghose by Tahami (2013). The description of new recorded species are as follows: 1. Aphanocapsa delicatissima West، W. & West، G. S. (1912) On the periodicity of the phytoplankton of some British Lakes. Journal of the Linnean Society of London، Botany 40:395–432. Syn.: Microcystis pulverea f. delicatissima (West، W. & West، G. S.) Elenkin 1938، M. delicatissima (West، W. & West، G. S.) Starmach 1966. Description: Colonies are spherical or elliptical in shape of free floating blue-green small cells which distributed frequently with equal distances throughout of a colorless glaze. Cells are 1 µm in diameter (Fig. 1. B). 2. Aphanocapsa rivularis (Carmichael) Rabenhorst، L. (1865) Flora europaea algarum aquae dulcis et submarinae. Sectio II. Algas phycochromaceas complectens. Pp. 1–319، 71 figs. Lipsiae [Leipzig]: Apud Eduardum Kummerum. Syn.: Palmella rivularis Carmichael 1833، Aphanocapsa anodontae Hansgirg 1892، A. endolithica Ercegovic 1925، A. endolithica var. rivulorum Geitler 1928، Microcystis anodontae (Hansgirg) Elenkin 1938، M. calciphila Schwabe 1947، M. anodontae var. rivulorum (Geitler) Kann 1978. Description: Irregular form or spherical floating colonies of round bright blue green cells which are single or in pairs with distance located in a mucilaginous sheath. Each cell is about 7 µm in diameter (Fig. 1C).
