What exactly is OVERLAY? I have heard several different explanations, could someone give me an easy definition? Thanks!

from http://www.shroomery.org/findorgrowthem/apprenticecasing.html

Overlay is the condition which results when mycelium has been allowed to completely cover the casing surface. It is caused by prolonged vegetative growth temperatures, high CO2 levels, and excessive humidity. If overwatered, the overlay will become matted, or, will form a dense, dead layer of cells on the casing surface.

A casing showing signs of overlay will begin to shrink and pull away from the sides of the container. It will also become unreceptive to water, and puddles may form on the surface after misting. If any pinheads form, they will likely do so at the edges of the casing. Most of the pinheads will abort, and only a few mushrooms will fully mature. Once this has happened, the casing layer really isn't a casing layer anymore. It is no longer serving it's three main functions, and has in essence become a second layer of non-nutritious substrate.

As previously mentioned, overlay is caused by prolonged vegetative growth temperatures, high CO2 levels, and excessive humidity. It results when the grower does not take the proper steps to initiate pinning, or, when the grower initiates the pinning strategy too late. As a general rule of thumb, the initiation process should begin as soon as mycelium is first visible in the valleys of the casing layer (or, when you can just barley make it out underneath the surface of the casing). However, Psilocybe Cubensis is a species which enjoys high mycelial momentum. Even after initiation of the pinning process, the mycelium will continue to grow for a period of time and consume more of the casing. This is why timing is critical.
