Cortinarius, Flora Photographica (4-Volume Set) [English]
This 4-volume set comes in three ringbinders (volumes 3 and 4 come in one binder). Each volume consists of a 30 to 40-page booklet, a collection of 60 loose leaf plates with colour photos, and, in the first binder, a series tabs to divide the subgenera and a packet of tabs for all the sectios.
From the preface:
"This flora was initiated during a one week seminar on the genus Cortinarius, arranged by the executive committee of the Swedish mycological Society (SMF) at Borgsjö, Medelpad, Sweden, August 1982. The committee was composed of members from Sundsvall Mycological Society (MYCO), and two of the members – Håkan Lindström and Jan-Olof Tedebrand – made contact with Tor Erik Brandrud, Oslo, and Jacques Melot, Paris, who conducted the seminar. For photographic documentation of the collected material Hans Marklund, Härnösand, was engaged.
After the seminar it was decided to continue to document the Cortinarius species in order to produce a photoflora of the genus, as complete as possible. A project group consisting of Tor Erik Brandrud, Håkan Lindström, Hans Marklund and Siw Muskos have since 1982 been involved in collecting and photographing the Cortinarius species for the flora.
The collecting has been carrried out by the members of the project group in their home districts (mainly the boreal zone in Central Scandinavia), and in connection with joint excursions to Southern Scandinavia (nemoral zone) and to the Scandinavian mountain range (alpine zone).
A study of the taxonomy and nomenclature of the photographed collections has also been carried out. The project group has in this connection also had contact with other Cortinarius mycologists, particularly Meinhard Moser, Innsbruck, and Egil Bendiksen, Oslo, who have contributed with valuable points of view. Klaus Høiland, Oslo, has studied the entire section Dermocybe material. During the comlete project period we have been in close contact with Jacques Melot, and since 1988 he has been included as a regular member of the project group. One of the major aims of the project has been to attain as broad as possible agreement among the scientists studying Cortinarius, about the taxonomy and the nomenclature of the genus.
Each species included in the flora is presented on one or more separate loose leaf colour plates. Due to the system of loose leaf sheets, species can be published continuously as soon as good photographs are obtained, and the nomenclature has been revised. This system also makes it possible to change the position of species in the taxonomic arrangement – if changes in the generic classification occur. Further it gives more flexibility in connection with taxonomic revisions. The reference code of each loose leaf plate is indicated in the upper right corner (ex. A 15). The systematic position of the species on each sheet is indicated in a special register sheet (Appendix).
The photographs (transparencies; 4,5 × 6 cm) have been taken in a studio with artificial lighting. This is to ensure as homogeneous and as natural colour reproduction as possible. A number of grey coloured wooden boards have been used as backgrounds for the specimens on the photographs.
The species descriptions have been prepared by Tor Erik Brandrud (subgenus Phlegmacium and Myxacium plus the sections Leprocybe and Cortinarius) and Håkan Lindström (subgenus Telamonia plus the section Dermocybe). The texts have been revised by the entire group, including Jacques Melot. The species descriptions are mainly based on our own material and are comparatively short. Only the typical and differential characters have been emphasized. More extensive descriptions and a wider taxonomical treatment of most groups are – or will be – presented in international mycological periodicals parallell to the issue of this flora (cfr. list of references). The nomenclature and taxonomy (with few exceptions) of the section Dermocybe follows Holland (1984). The species concept also corresponds with Nordic Macromycetes, and the forthcoming revision of Flore Analytique. Under the heading Protologue in the species descriptions a reference is made to the literature where the name has been validly published. The term protologue comprises all the elements that have been associated with the name in this first, valid publication. This applies even for icones cited, cited material, references, etc. List of references concerning the species desriptions are included in the Appendix.
A number of new taxa plus a number of nomenclatoric revisions are presented in the flora. All new names and combinations are validated parallell to the photoflora in the various mycological periodicals. For a number of species where the use of the name is stabilized, the photoflora material has been selected as neotypus. The neotypifications themselves will be published in some international mycological periodical. For a majority of new species (published by the present authors), the photoflora material is selected as a holotype, and the descriptions of these are published in mycological periodicals.
The text under the heading Collection in the species descriptions refers to the material in the photograph, when and where it was collected, plus its CFP (Cortinarius, Flora Photographica) number. Spore sketches have been drawn from preparates obtained from the
pictured material. The terms used in the species descriptions are explained in chapter 3 ”lntroduction to the genus”."
