A survey was made of the Boletales, Agaricales and Russulales, and
their mycorrhizal fungi in the Nothofagus forests in central
Chile between Talca (55°24’S—71°) and Angol (57°48’S—72°45’W).
This work is divided into two principal sections: 1. A mycorrhizal survey and 2. A systematical analyse.
A bibliographic compilation is given of all ectomycorrhizal fungi associated with Fagaceae (excluding Quercus). A total of 1198 mycorrhizal fungi (distributed in 108 genera) are established as fagaceous hosts. From these the Basidiomycetes is the most important group with 1159 taxa (96 genera), as opposed to the Ascomycetes which is represented with only 37 taxa (11 genera) and the Zygomycetes with only 2 species (1 genus). Within the 43 families the Cortinariaceae predominate with 516 taxa. They are followed by the Tricholomataceae with 158, the Boletaceae with 153 and the Tricholomataceae with 75 taxa. The Cortinariaceae is the most important mycorrhizal group associated with the southern beeches. From the Russulaceae 103 taxa are associated with Fagus and 38 taxa with Nothofagus.
In the systematic section around 170 taxa were cataloged, described and illustrated. From these 150 originated from central Chile and ca. 20 from southern Chile. The latter are included as species extralimitatae. The majority of the species belong to the families Cortinariaceae (52 taxa) and Tricholomataceae (51 taxa).
In addition, the following 5 maps are included: 1. Ectotrophic areas from South America, 2. Ecto- and anectrophic areas of central and southern Chile with the distribution of Nothofagus and its parasites, 5. Mycological survey areas in Chile, 4. Distribution of the genus Boletus in Chile, 5. Distribution of the genus Paxillus in the southern hemisphere.
