… the “velcro” tissue (Rod’s terminology), seen in many amanitas with a naked eye, courtesy of schizohymenial ontogenesis. This is why the gill edges are “sterile”. i.e., devoid of basidia (probably no cystidia either?).
Here is a quote from Rod found in his website:
“The sterile condition can be recognized as follows: In Amanita, the gill edge is comprised of a “cable-like” grouping of hyphae running the length of the gill edge and giving rise to balloon-like cells of various shapes (singly or in short chains) which separate, collapse, gelatinize, and/or break, facilitating the the separation of the gill edge from the stem or from the partial veil (ring, annulus, skirt) as the elements of the expanding Amanita basidiome are separating.”
