Trama (mycology) trama tends to be soft tissue, and in weaving, the woof yarn is not tightly stretched; it therefore need not as a rule be as strong as the warp yarn. 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
Amyloid (mycology) 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 a similar reaction, also called an amyloid reaction. The test can either be on microscopic features, such as spore walls or hyphal walls, or the apical apparatus on an ascus, or be a macroscopic reaction on tissue where a drop
