scierotium. scierotia: a resting stage of myce-

sterilization: the rendering of a substrate to a

hum typified by a mass of hardened

state where all hifeforms have been made inviable. Sterilization by heat (steam) is more
commonly employed in mushroom cultivation than chemical, gas, UV, or radioactive

mycelium resembling a tuber and from which

mushrooms, mycelia, or conidia can arise.
Sclerotia are produced by both ascomycetes
and basidiomycetes.
sector: usually used to describe fans of mycehum morphologically distinct from the type
of mycelium preceding and bordering it.
senescence: the state whereby a living organism
declines in vigor due to age and becomes susceptible to disease.

septum, septa(pl.) structural divisions between
cells, i.e. cell walls.

septate: cells with distinct walls.
skeletal hyphae: coarse, inflated cellular network consisting of thick-walled, unbranched,

cells lacking cross-walls. Skeletal hyphae
give mushrooms a tough, fibrous texture, especially at the stem base. Except for the basal
cell, they are typically clamp-less.

spawn: any material impregnated with mycehum, the aggregation of which is used to
inoculate more massive substrates.
species: a biologically discrete group of individuals which are cross-fertile, and give rise
to fertile progeny.

sporeless strains:Strains which do not produce
spores. Sporeless Oyster strains are highly
sought after given the health problems asso-

ciated with growing these mushrooms

longed exposure to temperatures at or above
the boiling point of water (100° C; 212° F.)
at or above atmospheric pressure.

stipe: the stem of a mushroom.

strain: a race of individuals within a species
sharing a common genetic heritage but differing in some observable set of features which
may or may not be taxonomically significant.

stroma: a dense, cushion-like aggregation of
mycelium forming on the surface of substrate

which generally does not lead to fruitbody
subhymenium: the layer of cells directly below
the hymenium.
substrate: straw, sawdust, compost, soil, or any
organic material on which mushroom mycehum will grow.

super-pasteurization: prolonged pasteurization utilizing steam. Super-pasteurization
typically is for 12-48 hours at or near to 100°
C. (212°F.) at or near atmospheric pressure.
Super-pasteurization is a method commonly

used to render sawdust substrates, in bulk,

into a form usable for the cultivation of
Shiitake, Oyster, andlor similar mushrooms.



spores: discrete cells which are used to spread
fungi to new ecological niches, arid are essential in the recombination of genetic material.

any fruitbody that produces

taxon (taxa p1.): a taxonomic unit, usually in
reference to a species.

thermogenesis: the natural and spontaneous
escalation of temperature in substrates due to
