Matchmaker Menu

Clicking on Matchmaker then Make a New Match gives access to the most important part of the program. The Matchmaker Entry Form comes up on the screen. It allows you to check off the characteristics you know about a mushroom you are trying to identify. When you press the SHOW MATCHES button, you will be presented with a list of species that match those characteristics. You can check the written descriptions to narrow the choices further.

Clicking on Matchmaker then Change the Match is available only after a match is made. It allows you to refine your search criteria. For instance if there are no matches, or you are not sure of some of your criteria, you may want to reduce the percentage of matches required before a species is displayed. You may also want to add more characters if there are too many matches, or if none of the matches seems to fits the characters you entered.

Clicking on Matchmaker then Best Characters is a choice available only after a match has been made. It analyses the selected species to see which other characters would be most useful to cut down on the possibilities. Clicking on any character listed will cause the list of selected species to include only those selected species that also match the new character.

Clicking on Matchmaker then View Characters Checked is a choice available only after a match has been made. It is a way to remind the user which characters are now checked. (Since the characters are checked on multiple pages of the entry form, it is easy to lose track of these.)

Clicking on Matchmaker then Compare To will show a chart of the differences between the highlighted species and the next one clicked. Since the computerized data is designed to reflect choices that the user might make (not the actual characters of the mushroom) and since anything left out of the description will not be reflected in the data, this choice must be used with caution. The default is to compare all features, but it can be changed to compare all differences under the Options Menu.

Clicking on Matchmaker then Undo Last Match is a choice available only after a match has been lost by making a new match or changing the match. It will return to the previous match.

List Menu

Clicking on List then All Gilled Species restores the initial list of all species after one of the other options on the List menu has been chosen.

Clicking on List then By Species lists the species alphabetically by their Latin species name. This is useful if the species name is easier to remember than the genus name.

Clicking on List then Alternate Names gives a list of species names that are not included in the main list but are old or alternative names for the species. This is used when the user does not find the desired species in the list. The descriptions are brought up as in the main list.

Clicking on List then English Names lists the species alphabetically by their English name. If there is a compound name it is listed both under the noun and under the adjective.

Clicking on List then Similar Species is not used with matching, but will compare the characters of all the species to see which match the highlighted species closely. It is useful when the user wants to browse through descriptions or illustrations of similar species.

Clicking on List then Families gives a list of all the families. Each family description may be shown on the right half of the screen by clicking on a family in the list, then clicking the Show Description button. This operates the same way as the species descriptions.

Clicking on List then Genera gives a list of all the genera. Each genus description may be shown on the right half of the screen by clicking on a genus in the list, then clicking the Show Description button. This operates the same way as the species descriptions.

Clicking on List then Tree View gives a branching tree of the families, genera, and species. Clicking on a name expands the branches and clicking again collapses them.

Clicking on List then Glossary gives a list of terms on the left of the main screen. Clicking on one of them and then clicking the Show Definition button brings up its definition on the right. This glossary option will replace the main page. All of your previous matches will be forgotten.

Clicking on List then Glossary (new window) brings up the glossary in a new window, so that your current work is not lost.

Clicking on List then Illustrated Gilled Species displays only those species from the main list that have illustrations. Otherwise, it works the same way as List then All Gilled Species.

Advanced Menu

Clicking on Advanced then Show Species Characteristics allows you to view the data for any species that will be used to compare it to the information you enter for a match. Positive characters in the description for that species are checked.

Options Menu

Clicking on Options then Larger Illustrations will use the larger of two illustrations when there is a choice of two sizes to use (about two thirds of the illustrations). This is useful if you have a fast connection and would prefer larger illustrations.

Clicking on Options then Smaller Illustrations will use the smaller of two illustrations when there is a choice of two sizes to use (about two thirds of the illustrations). This is useful if you have a slow connection and would prefer smaller illustrations to decrease download time.

Clicking on Options then Required Character Button will make visible the button which allows you to specify that a character must be matched for the species to appear in the list of choices. It is relevant to situations where species do not match at 100%. When you are making a match, and you are absolutely sure that a certain character will be included in the description, click on this button, then on the checkbox. The highlighting will change to light blue. The program will then avoid showing you species that lack this character, when matching at less than 100%. To turn off the required character property, click on the checkbox again. Be cautious using this button, because if an obvious character should happen not to be mentioned in the description, or should happen to be specified a little differently, the correct species will not show.

Clicking on Options then Negative Character Button will make visible the button which allows you to match all the species which do not contain a particular character in their descriptions. When this is activated, click on the button, then on the checkbox. The highlighting will be white. The Negative button must be used carefully because the data used for matching is designed to be inclusive rather than exact. For instance, if the thickness is unknown for the cap flesh, both thick and thin are generally checked, so that they will not interfere with the match if you choose thick or thin. If negative thin is chosen, however, the species will not match at 100%. This is why it is given only as an option.

Clicking on Options then Enable Compare All Features will set the user preferences so that when Compare To is selected from the MatchMaker menu, it will show a chart of all the features of the highlighted species as compared with the next one clicked. Since the computerized data is designed to reflect choices that the user might make (not the actual characters of the mushroom) and since anything left out of the description will not be reflected in the data, this choice must be used with caution.

Clicking on Options then Enable Compare Differences will set the user preferences so that when Compare To is selected from the MatchMaker menu, it will show a chart of the differences between the highlighted species and the next one clicked. Since the computerized data is designed to reflect choices that the user might make (not the actual characters of the mushroom) and since anything left out of the description will not be reflected in the data, this choice must be used with caution.
