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.
