From: Alcobiosis, an algal-fungal association on the threshold of lichenisation
Snail-grazed Skvortzovia furfuracea. (A) a green area of exposed algal layer formed by snail grazing; (B) regenerated mycelium overgrowing grazed areas. Algal cells are indicated by the red chlorophyll autofluorescence. (C) fresh snail excrement; (D) excrements are quickly overgrown by regenerated mycelium; (E) the red chlorophyll autofluorescence indicates high density of Coccomyxa cells in an excrement; (F) a mixture of Coccomyxa and remnants of fungal tissue in an excrement. Scales: (A) 2 mm; (B) 0 µm; (C, D) 1 mm; (E, F) 20 µm.
