Abstract: 2 tables. 9 figures. ["It was estimated tentatively that, on an overcast day, cryptoendolithic lichens may have been photosynthetically active for about 15 h, although these conditions were suboptimal. On a clear and windy day, photosynthesis may have been possible for 11 h, with 4 h optimal activity. On a clear, warm and clam day, the estimates amounted to 13.5 and 6.5 h, respectively."]
