Abstract

Cryoseston algae and microfungi were recorded, for the first time, on Mt. Olympus, Greece. In total, 16 species from 10 sites were found. At lower altitudes (1622 m. a. s. l.), Chloromonas nivalis dominated in 2 sites, but at a higher altitude (2680 m. a. s. l.) only Chlamydomonas cf. nivalis was found. In one field (2149 m. a. s. l.), these two algae coexisted. The rare taxa Gloeocapsa sanguinea and Xenococcus kerneri (new cryoseston), as well as cf. Cystococcus nivicolus, cf. Stichococcus allas, Trochiscia cf. americana, cf. Chaepinnularia krokiformis and Surirella linearis var. linearis were also found. Some localities were colonised only by the fungi Chionaster nivalis, Selenotila nivalis and a few incorrectly described snow fungi (cf. Bacillispora aquatica, cf. Arthrobotrys superba, cf. Tricladium angulatum, Alternaria sp.). Selenotila proved to be a pollen grain saprophyte of Corylus sp. while Myzocytium sp. was a saprophyte in pollen grains of Pinus peuce. Macroscopically, the snow was only slightly coloured when samplings were carried out at the end of May and the beginning of June 2015.
