Abstract

Mallomonas acaroides Perty emend. Ivanov bloom in the Calcescu subalpine lake of the Parang Mountains, Romania. Plankton samples collected in autumn 1992 from the glacial Calcescu Lake, located at an altitude of 1924 m in the Parang Mountains, southern Carpathians, revealed an unexpected bloom of Mallomonas acaroides var. acaroides. according to TEM observations the population was very uniform, exhibited individuals with elongated, ellipsoidal to almost cylindrical cells bearing all over their surface outstandingly long, slender bristles, with helmet shaped tips. Bristles lacking helmet shaped tips, with gradually tapering distal ends and recurved proximal teeth were also present, but very rare. Most individuals possessed very thin, poorly silicified, imbricated scales, mostly without or with rudimentary meshwork on the shield. This is the first record of such Mallomonas bloom in a Romanian alpine lake, very similar with that documented by Kristiansen in a Bulgarian mountain lake.
