The second instalment of Agerer’s colour atlas of ectomycorrhizae containing 12 doublesheets each with four good to excellent colour photographs and two sets of black-and-white photomicrographs of external and internal structures of the same mycorrhiza. The following mycorrhizae are illustrated: Cenococcum geophilum, Cortinarius obtusus, Piceirhiza nigra, P. obscura, and Tuber puberulum, all on Picea; Fagirhiza cystidiophora, F. granulosa, F. tubulosa, and Laccaria amethystina, all on Fagus; Dermocybe crocea and Rhizopogon luteolus on Pinus. The introduction of this work has been rewritten and considerably extended (from 16 to 32 pages), whereas an appendix is added with synoptical tables for the most conspicuous characters (host tree, surface structures, colour and microscopical characters of the fungal sheath).
