it was so low that one had to bend to enter the cave (KADIC 1915). Now it is 3 m high and 4 m wide. Before the entrance there is a huge heap of rocks built during the excavations (Fig. 3). This wall throws a shadow on the very beginning of the cave. The first hall of the cave is rather bright, even direct sunshine can be seen round noon. Immediately after the excavations KADIC (1915) reported that on the N wall of this hall one could see mosses and algae, being very picturesque in green, lilac, yellow and green colours. The climate of the cave is rather even, the air humidity is high (LOKSA 1962). Register number in the Hungarian Cave Survey: 5363/1. METHODS We visited the cave Lök-völgyi-barlang in 25. April, 1985. and the cave Szeleta-barlang in 26. April, 1985. The algal coat were scraped off with a knife sterilized by burring before taking each sample, and put into presterilized collecting tubes filled with inorganic fluid Bold medium (STEIN 1973). Within 12 hours all the samples were divided into two. One part of each sample was fixed by formaldehyde solution (2-4%), the other part was cultivated in the laboratory (room temperature, 12 hours light - 12 hours darkness). After 1, 9 and 15 months of cultivation these samples were examined under microscope. This way we united the advantages of the "direct method" (cf. HAJDÚ & ORBÁN 1981) and of the cultivation method used by us in our previous work (P.-KOMÁROMY & al. 1985). Thus we could get a better knowledge on the frequency relations of the original flora from the fixed sample and the cultivated samples helped in the identification of the coccoid green algae (reproductional stages) and in finding those species which are too rare. The cultivated samples are essential when the original scraping contained too much inorganic matter. On the first occasion P.-KOMÁROMY identified the algae. The identification of the fixed material and the 9 and 15 months old samples were carried out by BI T C ZKÓ. Per manent diatom slides were made when required with the hydrogen peroxide method of HORVÁTH (1975). Four samples were taken from Lokvölgyi-barlang and 11 from Szeleta-barlang (Table 1, Figs. 2-3). Mosses were collected from all of the surfaces where they were observed. The presence of ferns and fern prothallia were only noted in the field-book. The former unpublished bryophyte collections were revised as well (Ló'kvölgyi-barlang: BOROS 22.05. 1937; Szeleta-barlang: BOROS 29.05. 1928; VAJDA 21.10. 1969). The nomenclature of mosses follows DUELL (1984, 1985). Either the bryophyte specimens or the alga samples ig. 2. The map of the cave Lök-völgyi -barlang are deposited in BP.
