Q R S T

R

Rhizomorphs
Long lace webs of hyphae. They carry water and nutrients from the mycelium to fruiting bodies and ensure fungi life under unfavourable conditions.

Ring
A rim left from sectional veil on brewits stalk.

S

Saprophyte
An organism living on the remains of plants and animals turning organic matter into the inorganic one.

Saprophytes
Fungi living on dead organic matter, mainly on the decayed parts of plants. Their feed by decomposing dead plant remains.

Sectional veil
The protective coat of fungi hymenium spanned from the cap edge and a stalk. As a fungi matures it tears to release formed spores.

Sowing mycelium
Sterilized wheat, rye or millet inoculated with mycelium germinated from spores or fungi tissue. It is delivered to mushroom-growers in special plastic bags or bottles.

Spawn
(or mycelium), a typical fungi body found in substrate consisting of very thin interwoven branched web-like filaments (hypha).

Spores
The reproductive cells («seeds») of fungi, bacteria and plants.

Sterilization
(Lаt. sterilis)
Disinfection, the act of annihilating microorganisms with a high temperature, chemicals or by filtration.

Strain
A group of microporganisms (e. g. fungi) with its own peculiarities and strong points. (like a plant kind or an animal breed)

Stroma
A compact pillow-like mass of mycelium, formed on the compost or cover mixture. It indicates that a mushroom will reproduce asexually.

Substrate
(Lat. substratum)
The material on which mycelium grows (this can be a tree, soil, compost, grain, etc.).

Substrate dampness
(absolute humidity)
The degree of moisture in the substance expressed in %. The index is calculated according to the formula Humidity = (wet weight – dry weight)/dry weight*100%

T

Tamping
The process of stowing substrate tightly. Note that substrate is not exactly tamped: e. g. while stowing compost into the substrate is compressed under 100kg/m pressure, i. e. slightly tamped.

The first stage
The first composting stage, during which raw materials are mixed, moistened and processed into the nutrient medium for growing mushrooms.

The second stage
The stage, during which mushroom compost is pasteurized and conditioned.

Thermal probe
A device for measuring the temperature in the compost

Thermophiles
Microscopic organisms growing and reproducing at a rather high temperature (70ºС).

Tide
Simultaneous mass mushroom maturing.

Tossing
Tedding a substrate pile while composting it and turning it upside down.
