Trama (mycology) Trama (mycology) In mycology, trama is the inner, fleshy portion of a mushroom's basidiocarp, or fruit body. It is distinct from the outer layer of tissue, known as the pileipellis or cuticle, and from the spore-bearing tissue layer known as the hymenium. In essence, the trama is the tissue we call the "flesh" of mushrooms and similar fungi. Literally, "trama" is the Latin word for the "weft" or "woof" yarns in the weaving of cloth. This probably is related to the basidiocarp trama being "filler" tissue and that analogously the woof yarn in weaving is sometimes called "fill". Furthermore, the
Amyloid (mycology) of the reagent is applied. Negative reactions, called inamyloid or nonamyloid reactions are for structures that remain pale brown or clear. A reaction producing a deep reddish to reddish-brown staining is termed either a pseudoamyloid reaction or a dextrinoid reaction. Amyloid (mycology) In mycology a tissue or feature is said to be amyloid if it has a positive amyloid reaction when subjected to a crude chemical test using iodine in either Melzer's reagent or Lugol's solution, producing a black to blue-black staining. The term "amyloid" is derived from the Latin "amyloideus" ("starch-like"). It refers to the fact that starch gives
