Books received by the Rijksherbarium library

This is the first delivery of what is meant to become a long series of coloured and black-and-white photographs of ectomycorrhizae, arranged according to fungal species. Of each species a plate with four high-quality colour photographs of the mycorrhizae at different magnifications are provided together with an additional series of half-tone photographs showing important characters, such as details of structures, mantle, and rhizomorphs, both in surface views and in sections. The colour of the mycorrhizae is considered to be of prime importance for the identification of a species. A key and synoptic tables are included for determination of the mycorrhizae shown. Each year 10—15 plates will be delivered as part of a loose-leaf system. Finally this will contain 200—300 species.
