Abstract:

The number of edible fungi which have been successfully cultivated under unsterile conditions is still very limited. Although many species are known to be edible the production of cultivated mushrooms is dominated by Agaricus bisporus (Lange) Sing., which accounts for approximately three-fourths of the total world’s production. The next important species in terms of world output is Lentinus edodes Volvariella volvacea (Bull. ex Fr.) Sing. (Paddy straw mushroom), Pleurotus ostreatus Fr. (Oyster mushroom), Auricularia (Ear mushroom) Tuber (Truffles) and the jelly fungus, Tremella (San Antonio, 1975).

The production of A. bisporus is predominantly a crop of the temperate world but it has been successfully introduced in various sub-tropical countries like Mexico, South Africa and Taiwan in particular. The success of this species can be attributed to its easily procured straw based substrate and to the scientific approach of its method of cultivation. Volvariella is being extensively grown in South East Asia, while in Madagascar its cultivation has been attempted on various industrial vegetable residues and on rice straw (Bouriquet, 1964). The production of both A. bisporus and V. volvacea is being tried in Mauritius.

The work presented in this paper is a preliminary investigation of an indigenous edible species. The domestication of new edible mushrooms is well known to be a most challenging problem because the environmental and physiological factors involved in the control of their morphogenesis and reproduction are unknown at the outset and extremely difficult to elucidate. However the association of a giant species of Tricholoma with the sugar cane plant (Peerally and Sutra, 1972, 1973) has posed a problem worthy of investigation for several reasons among which may be cited:
(a) its excellent taste,
(b) its prolific natural production of sporophores
(c)and the position of sugar cane as the predominant crop in Mauritius.

Species of Tricholoma have been reported to be edible. T. nudum Quel. and T. personatum (Fr.) Quel, occur in the temperate areas. T. mongolicum Imai has been described as the most delicious mushroom of Eastern Asia (Heim, 1969b). T. caffrorum kalch. and McOvan is a well known edible species in South Africa. The edible T. mauritianum Peerally and Sutra has been reported from Mauritius (Peerally and Sutra, 1972, 1973). Of these species only the cultivation of T. nudum has been attempted (Constantin and Matruchot, 1901; Matruchot, 1908 a, b, c; Heim, 1942). A non-edible rare speci
