The Effect Of Different Media On The Mycelial Growth Of Pleurotus Pulmonarius

ABSTRACT

The use of the word "mushroom" is often restricted to an umbrella a. shape reproductive known as carpophore or basidiocarp with gills on the lower surface belonging to basidioniycotina. In a general concept however, a mushroom is a reproductive structure of any fleshy fungus, generally edible in nature irrespective of whether it is an agaric or not (Nair and Balakristian, 1995). In popular usage, mushrooms arc fungi that produce conspicuous fruit bodies. The only visible part of a fungus, fruit bodies vary from the well known sap and steam type (Nair el al., 1995). The modern and more acceptable definition of mushroom is that they arc sp01e — producing fruits bodies of higher fungi that develop from an extensive mass of line thread-like hyphac, which are collectively known as mycelium, Presentin the ground or other substrata on which the f'ungus grows (Chang, 1992).
