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.

Similar attention has been given to the concepts of "natural selection" (what is the target of natural selection? - the individual? the environment? the genome? the species?); "adaptation; diversity and classification; species and speciation"; and "macroevolution".
