Abstract

The mycelium of the basidiomycete is not uniformly competent to differentiate. Differentiation occurs only in localized areas of young mycelia. Studies on laccase activities from whole mycelium extracts suggest a correlation between overall laccase levels and the development of mushroom primordia. However, studies of higher resolution on the localized areas of developmental competence, under a variety of light, nutrient and temperature regimes, indicate that laccase is probably not involved in the actual development of the primordia. If laccase is involved in differentiation, it is only at the initial, light-requiring, step.
