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
Biology: The Unity and Diversity of Life Biology: The Unity and Diversity of Life Biology: The Unity and Diversity of Life is a college-level introductory biology textbook that helps students learn how to apply critical thinking and scientific methods to developing their understanding of basic concepts in molecular biology and biochemistry, genetics, biotechnology, reproduction and embryonic development, anatomy and physiology of plants and animals, evolution, taxonomy, and ecology. The book is designed to create in students a broad foundation of knowledge in biology and is frequently used in AP Biology classes in American high schools. Each book includes an interactive CD-ROM with links to additional instructional material.
