nails (6 penny) slightly offset relative to one another. With this "scratching stick", the casing is
lightly ruffled prior to the mycelium breaking through to the surface. After the surface has been
scratched, the casing should be given its final waterings prior to pinning.
A modified application of this technique is "deep scratching". When the mycelium is midway
through the casing, the entire layer is thoroughly ruffled down to the bulk substrate. The agitated
and broken mycelium rapidly reestablishes itself and within three to four days it completely colonizes the casing. The result is an early, even and prolific pinhead formation. Before using this
technique, the grower must be certain that the substrate and casing are free of competitor molds
and nematodes.

Casing Moisture and Mycelial Appearance
Moisture within the casing layer has a direct effect on the diameter and degree of branching
in growing mycelium. These characteristics are indicators of moisture content and can be used as
a guide to proper watering.

1. Optimum Casing Moisture: Mushroom mycelium thrives in a moist humid casing,
sending out minute branching networks. These networks expand and grow, absorbing
water, CO2 and oxygen from the near saturated casing. This mycelial growth is characterized by many thick, white rhizomorphic strands that branch into mycelia of smaller diameters and correspondingly smaller, finer capillaries. The overall aspect is lush and
