Notes on Descriptions

LATIN NAME(S) Alternate Latin names are given after the Latin name in the description, and include names thought to represent the same species or part of it. If there is a question about the inclusion of the alternate name in the species, or if the alternate name is used to include more than the main species name, a question mark precedes the alternate name.
ENGLISH NAME(S) English names are listed under English names in the List menu both by the adjective and the noun. The names are generally taken from field guides. A few obvious English names derived from the Latin name are added: they are enclosed in single quotes.
NOTES Information includes Subgenera, main distinguishing characteristics, frequency, and distribution. Frequency and distribution are not given separate categories because it is not available for a large enough proportion of species. A separate section starting with CHEMICAL REACTIONS may be included for reactions of the cap, flesh, or stem to various chemicals.
CAP Size is in the format (2)4-20(25)cm, where 4-20 is the usual range of diameter for mature caps, with occasional caps as small as 2cm or as large as 25cm. The (2) or the (25) may be omitted, and "in" may be used instead of "cm" if the descriptions have been converted to "in" format. Then shape, color and surface are described, each separated by semi-colons.
FLESH Although this section refers primarily to the flesh of the cap, notes about the flesh of the stem may be included here. For Lactarius species a separate section starting MILK is included here.
GILLS Notched gills are considered to include emarginate, sinuate and uncinate attachments.
STEM Size is in the format (5)10-15(20)cm x (0.1)0.5-1.2(2.0)cm, where 10-15 is the usual height of the stem, 0.5-1.2cm is the usual thickness, and the other figures are occasional extremes. Then shape, color and surface, each separated by semi-colons.
VEIL Both partial veil and universal veil may be described here. If there is a volva, describe it after a semi-colon starting with the word VOLVA.
ODOR "mild", "not distinctive", and "none" are slightly different in meaning but are often used interchangeably.
TASTE This refers to the taste of a tiny piece of the raw mushroom, touched to the tip of the tongue before spitting it out.
EDIBILITY The category here is taken from field guides, not from the experience of the writers. Do not eat any species based on knowledge derived from this program alone. Experience and competent first hand advice is required.
HABITAT Season is usually noted only for spring and summer species, as months usually vary with latitude and altitude within the Pacific Northwest.
SPORE DEPOSIT This refers to the color of spores on white paper, as produced when a cap is left overnight gill side down.
MICROSCOPIC Size of spores is in the format (5.5)6.5-7(7.8) x (2.5)3.5-4.5(5) microns, where 6.5-7 is the usual length of the spores, 3.5-4.5 is the usual width, and the other figures are occasional extremes.
height="77" NAME ORIGIN English meaning of the Latin species names found in a field guide is in double quotes, and derivations worked out from the Latin or Greek are in single quotes.
SIMILAR Other similar species and their distinguishing characteristics are given here.
SOURCES These are the authors of the books or articles where there are descriptions. Generally the author of the primary description used comes first. An asterisk after the name indicates an illustration.
