Publisher Summary Basidiomacromycetes represent a circumscribed group of higher fungi of the class Basidiomycetes, wherein the basidia bearing the exogenously produced basidiospores represent the fertile layer (hymenium), which in turn is lined up, encroached, and covered by tufts of tissues to form distinct objects of the Earth's beauty, namely the basidiocarps. Genetic incompatibility factors (bipolarhetrapolar) allow these fungi fungi great diversity in their ability to grow over a range of conditions: fermented or unfermented; pasteurized or unpasteurized; sterilized or unsterilized; on soft woods or hardwoods; on cereal straws or oil crop residues, or plantation crop residues. Moreover, Basidiomacromycetes display an array of physiological properties that have a range of useful applications. Edible species represent the best examples: they grow over a range of lignocellulosic substrates to yield fruiting bodies, and the degarded substrates can in turn be used in a number of useful ways. The search for new species of basidiomacromycetes and research on new and different ways to use these fungi should be a matter of priority. It is a task that requires much intelligence and perseverance. Increasing the list of their applications depends on prolonged and continued research. It can take the ingenuity of mankind, coupled with nature's mercy, to unravel the untapped potentialities of the basidiomacromycetes.
