TAXONOMIC REFERENCES
Nomenclature, Taxonomic Hierarchy, Author Names

Myconet (This is the most recent, regularly updated "

CABI Biosciences   
CABI maintains several very useful Taxonomic Databases for Names of all Fungi (including Lichens).
Especially the following ones are particularly helpful (the taxonomy of the Ascomycota follows theDictionary of Fungi, and is not identical with Myconet):

        Taxonomic Hierarchy (Search of Higher Groups of Fungi)

        Family Names (Search for Family Names of Fungi)

        Index Fungorum (Search for Names of Genera and Species; extremely valuable search
        tool for references to authors, publications and types)

Standardized Abreviations of Author Names 
THE STANDARD 
[according to BRUMMIT and POWELL (1992, regularly updated!)]

ING - Index Nominum Genericorum (Database of Genus Names maintained by the Smithsonian)

ITIS - Integrated Taxonomic Reference System (General Database on Taxonomic Names)
