  • The program itself works the same way as in recent versions.

  • About 140 species have been added. Many of these are new to science, particularly in Cortinarius. Other species have been added because there is better documentation of their presence in the Pacific Northwest.

  • About 300 primary names have been changed. In the three years since MatchMaker was updated, taxonomy has seen significant reorganization due to the study of fungal DNA. Other proposed names that we have not yet accepted are given as synonyms with an explanation in parentheses, for example "(proposed new name)". If you can't find a familiar name, use Index All Categories on the List menu, or type the familiar name into the search box on the matching form.

  • Several important new books have been published including Richard Kerrigan's Agaricus of North America, Jim Ginns' Polypores of British Columbia, and two new field guides for California. The more recent of these is Siegel and Schwarz's, Mushrooms of the Redwood Coast - it contains a lot of useful information for our area and beautiful photography.

  • The NOTES and SIMILAR sections of MATCHMAKER have been largely rewritten, this time in sentence form for easier reading.

  • We have made more use of single quotation marks and group designations for the names of species:

  • "group" implies that there are multiple named species that look similar, and

    1. we don't know which occur in the Pacific Northwest, or

    2. the members of the group are difficult to distinguish and referring to collections by the group name is convenient.

    The single quotation marks imply that we are using an unsatisfactory name. This may be because

    1. the name has not been published (e.g. Agaricus 'integer' and Isaacs' Agaricus names,

    2. the name may be invalid for some other reason (e.g. Amanita 'alba'),

    3. the name has been used for different concepts (e.g. Peziza 'repanda'),

    4. there are uncertainties about the correct name (e.g. Amanita 'pantherina', Claudopus 'parasiticus', Cortinarius 'rigidipes', Mycena 'alcalina', Mycena epipterygia var. 'viscosa', Mycena 'parabolica', Russula 'abietina'),

    5. we are using the name of a similar species, often European, which is likely to be different, but a new species has not been described (e.g. Tricholoma 'caligatum'),

    6. the name is unsatisfactory for some other reason, or

    7. combinations of the above.

    There are other names that represent a group of species, including 'clade' and 'complex'. The former refers to species that appear to be genetically related and is usually used by molecular biologists. 'complex' is sometimes used the same way we use 'group', but sometimes used to indicate genetically related species. Other expressions are 'affin.' and 'cf.'. Either is appropriate when you are using the closest name available, but there is uncertainty about the identification. 'affin.' can sometimes carry the implication of genetic relatedness. 'cf.' can sometimes carry the implication that differences are noted from the named species. We do not use any of these terms in the LATIN NAME(S) section of the description.
