16 Cellular Basidiomycete–Fungus Interactions 271
Fig. 3. Hypha of Colacogloea peniophorae (lower cell) in contact with a host hypha (upper
cell). The electron-opaque core (c) of the colacosome intrudes into the cell wall of the
parasite. Note the tripartite membrane (arrow) around the core of the colacosome (c).
The colacosome is covered by a thin secondary cell wall layer (arrowhead) and the
plasma membrane (double arrowhead) of the parasite. Bar 0.1 µm
