Abstract:

The South African white parasol, Macrolepiota zeyheri (Fr.) Sing. (Singer 1975) is a common edible mushroom growing in open stretches, pastures, along roads and in mountainous terrain, but not in forests or dense bush (Stephens and Kidd, 1968) . It is found throughout South Africa and is quite common during the rainy season. This is a large and conspicious fungus (Figure 1) and the thick fleshy, scaled white cap, with a diameter of 10-22 cm, and with its shallow cream to brown umbo is supported on a stem, 10- 20 cm long (Pearson, 1950) . Since this mushroom has a superb taste, resists insect infestation, has a good shelf life and is more nutritious than the cultivated mushroom Agaricus bisporus (Wehmeyer et al. 1981), a research project was initiated to study the physiology and possible commercial cultivation of this remarkable species. The aim of this paper is to summarize the present state of knowledge regarding aspects of the nutritional requirements, cultivation and nutrient content of M. zeyheri.
