Species composition of cryoseston was studied in the Vitosha Mountains (Bulgaria). In May 2005, snow fields were large, at the edge of timber line, not coloured but with dirty surface. The snow algal community was dominated by zygospores of Chloromonas nivalis (syn.Scotiella nivalis) and zygospores of * Chloromonas brevispina (syn. Cryocystis brevispina). In July 2005, only a few small snow fields with characteristic shell-form surface persisted above timber line; one field had a very light pink tint. Zygospores of Chloromonas nivalis were again dominant, but characteristic alpine species of snow algae, Chlamydomonas cf. nivalis and * Chloromonas rostafińskii, as well as cells of * Chromulina elegans and * Stichococcus bacillaris f. cryophila were also observed in the samples. Chlamydomonas cf. nivalis was dominant in late June 2006, forming patches of red snow on snow fields in the alpine zone (2100 m a. s. l.). In addition to algae, we also identified two fungal species in our samples from the Vitosha Mountains: Chionaster nivalis and * Selenotila nivalis. This is the first record of cryoseston from the Vitosha Mountains. Five taxa (*) are newly recorded for Bulgaria.
