Association of Skvortzovia furfuracea and Coccomyxa (GPS: 48.6679583N, 14.7053083E; voucher: PRA-JV25255). (A) typical habitat – shaded surface of rotten spruce trunks; (B) S. furfuracea crust grazed by snails; (C, E) vertical sections of S. furfuracea crust. Fungal tissues coloured by lactoglycerol cotton blue. A distinct algal layer is visible below a dark blue fungal coat; (D) the red chlorophyll autofluorescence indicates locations of Coccomyxa cells in the vertical section; (F) Coccomyxa loosely integrated in the fungal tissue. Scales: (B) 1 cm; (C, D) 50 µm; (E) 20 µm; (F) 10 µm.
