TERM DESCRIPTION
Saccardo's umber close to date brown, dark yellow brown
saccate of a volva, shaped like a sac, cup or sheath
salmon-buff a dingy pink
sanguineous blood-red
saprobe saphrophytic organism
saprophytic living on decaying organic matter
sarcodimitic consisting of generative hyphae and thick-walled, long, inflating fusiform elements, as in Gerronema
Sayal brown close to cinnamon in color, dull to dark cinnamon; between a moderate orange and a moderate yellowish-brown
scaber short projecting scale or tufted hairs
scabrous roughened by short projecting rigid scales
scale piece of tissue on surface that is not especially elongated, differentiated from surface by color or by projecting from it
scarlet a brilliant red color slightly tinged with orange
sclerotium a knot or firm frequently rounded mass of hyphae, usually underground, sometimes giving rise to mycelium or a fruiting body
scrobicula (plural scrobiculae) a large conspicuous shallowly sunken spot, pit, hollow, or depression
scrobiculate having scrobiculae, pitted with conspicuous wet-appearing slightly depressed areas
scum-like of cap, having an area of superficial dark-colored fibrils
scurfy surface covered with branlike particles resembling scales, same as furfuraceous
seceding refers to gills that have separated in their attachment to the stem and have the appearance of being free, often leaving longitudinal lines on the stem where the gills were once connected
secondary spores not borne on basidia, conidia, chlamydospores etc., formed directly on the mycelium or on hyphae of the fruit body
secotioid suggesting an undeveloped or aborted gilled mushroom, resembling Secotium
senescent becoming old
sensu in the sense of
sensu lato in a wide sense
sensu stricto in a narrow sense
separable said of stem or gill easily removed from cap
separate of gill attachment, same as secede
sepia a moderate brown; a brownish gray to a dark olive-brown
septate partitioned with cross-walls
septum (plural septa) cross-wall in hyphae
sequestrate describes fruiting bodies that have evolved from those that forcibly discharge spores to a closed or even underground form in which spores are retained until it decays or is eaten by an animal, the word referring to spores which have been sequestered (hidden). Lactarius is thought to give rise to Arcangeliella (mostly above ground, but gills not exposed or vertically oriented and do not discharge spores forcibly) and Zelleromyces (underground, no true stem). Russula is thought to give rise to Macowanites (mostly above ground), Gymnomyces (underground, no stem), Elasmomyces (no sphaerocysts in hymenial tissue), and Martiella (no sphaerocysts in hymenial tissue, underground without stem). Cortinarius is thought to give rise to Thaxterogaster (above ground) and Hymenogaster (underground, no stem). Agaricus is thought to give rise to Endoptychum and Longula. Chroogomphus is thought to give rise to Brauniellula (often buried or half buried). Pholiota is thought to be related to Nivatogastrium (grows on wood). Other postulated sequestrates are given in brackets: Amanita (Torrendia), Bolbitiaceae (Gastrocybe), Boletus (Gastroboletus), Coprinus (Podaxis), Entoloma (Richonia), Gomphidius (Gomphogaster), Lepiotaceae (Notholepiota), Paxillaceae (Austrogaster, Gymnopaxillus), Strobilomycetaceae (Gautieria), Suillus (Rhizopogon, Alpova, Truncocolumella, Gastrosuillus).

species classification grouping below family and genus, often used for organisms capable of interbreeding (though less common "hybrids" can occur between species), among anamorphic fungi that are not known to breed sexually, it refers to a certain level of similarity in form or function; named by genus name in upper case and species name in lower case, e.g. Russula emetica
spermatic resembling the odor of human sperm or semen
sphaerocyst, spherocyst a round or swollen cell in flesh of certain mushrooms, particularly Russula and Lactarius
sphaerocyte, spherocyte round cell of pellis or veil
spine long slender sharp projection
spiny having many spines
sporadic irregular in its occurrence, either in time or location
spore reproductive cell or "seed" of a fungus, produced on specialized cells, which in gilled mushrooms are on the gills
spore print a visible deposit of spores obtained by allowing a gilled mushroom to drop spores onto white paper for a few hours or overnight
spore wall in the most complex spore wall there are five layers from outer to inner: perisporium, non-pigmented and usually enveloping spore like a bag which may disappear; exosporium, usually non-pigmented and can often be distinguished chemically from other layers, episporium, a continuation of outer wall of basidium, the thickest layer and the one providing structural support, mesosporium, a barely distinguishable delicate structure, and endosporium, which can vary from very thick (in which case it can then be divided into inner and outer part) or seemingly absent, or truly absent; the presence or absence of layers varies with species
sporocarp a structure in which or on which spores are produced, often used for fruiting body, consisting of cap, gills, and stem
spotted with roundish areas different in color from the rest of the surface

subcrowded a term used occasionally of gill spacing, intermediate between close and crowded, might also be used to mean more or less crowded
subdecurrent of gills, meaning short decurrent or nearly decurrent or somewhat decurrent (i.e. intermediate between adnate and decurrent, when attachment extends slightly further down stem than when adnate)
subdistant of gill spacing, intermediate between close and distant, the order being crowded, (subcrowded), (subclose), close, subdistant, distant
subfusiform of spores, elongated, tapered at one end and rounded at the other
subgills the short gills that do not span the entire distance from margin to stem
subglobose of spores, nearly spherical or round; according to one set of criteria (Bas' work on Amanita) ratio of length to width 1.05-1.15
subhymenium a differentiated tissue just beneath the hymenium
subicule same as subiculum
subiculum a net-, wool-, or crust-like growth of mycelium under fruiting bodies
subisodiametric of spore sizes, the average length divided by the average width has a value from 1.16-1.27: with isodiametric spores this value is 1.0-1.15, and with heterodiametric spores it is greater than 1.27
subpellis the layer that separates the pellis from the trama; often considered the same as the hypoderm

subviscid slightly sticky, thinly viscid
sulcate grooved, furrowed
superior of a ring, forming on the upper part of the stem
suprahilar disc same as plage
suprapellis the outermost layer of the pellis, it may be undifferentiated (cells not distinct from those of underlying flesh), derm (cells arranged perpendicularly to surface), or cutis (cells arranged more or less parallel to surface)
synonym another name for the same species, especially an earlier or illegitimate name not currently used for the species; if two or more names are based on the same type, they are homotypic synonyms, sometimes indicated by three horizontal lines between the two names, but if they are based on different types, they are heterotypic, sometimes indicated by two horizontal lines between the two names; in this program, alternate names following the primary name are earlier or later or illegitimate names representing all or part of the concept of the primary name: the primary name includes the alternate name, but the alternate name may not include the whole taxon represented by the primary name
synonymous representing the same species
synonymize subsume a species name under another species name
