From: Alcobiosis, an algal-fungal association on the threshold of lichenisation
Chlorophyll fluorescence imaging of fungal-algal associations. Minimal fluorescence (Fo), visual frame and maximal quantum yield of photosyntem II (Fv/Fm) for Resinicium bicolor-Coccomyxa (A, B, C, J, K), Skvortzovia furfuracea-Coccomyxa (D, E, F, L, M) and Lyomyces sambuci-Desmococcus (G, H, I, N, O). Each sample contains both algal patches and alcobiosis where fungal crust completely covers the algae. Bottom pairs of frames demonstrate shielding effect of fungal crusts. Upper frames are intact alcobioses (J, L, N), whereas fungal part of the system was carefully removed by razor blade in red frames of the bottoms (K, M, O).
