Pink oyster mushroom has economic value, non-cholesterol food source and high nutrition. Gliricidia leaves and rice husks are abundantly available in nature, but not utilized optimally yet. They contain nutrients for the growth and development of pink oyster mushrooms. This study aims to determine effect of gliricidia leaves and rice husks as additional supplements to growing media on the growth, yield, and nutritional content of pink oyster mushrooms. The study used completely randomized simple design consisting of six treatments, repeated four times. The treatments consisted of control, 150 g rice husk + 30 g gliricidia leaves; 120 g rice husk + 60 g gliricidia; 90 g rice husk + 90 g gliricidia; 60 g rice husk + 120 g gliricidia; 30 g rice husk + 150 g gliricidia. The data were analyzed using analysis of variance with F test. The results showed addition of gliricidia leaves and rice waste in form of rice husks as additional supplements to pink oyster mushroom growing medium was able to increase production by 2.2 times or 120 %; increase the nutritional value of mushrooms as indicated by an increase in protein, ash, and water content; and reduced fat content.

Based on the literature and an ethnomycological survey in the dense rainforests of Ivory Coast, the number of edible fungi of Ivory Coast now counts sixty-seven species. All species are listed and local names are given in Abidji, Bété and Gban languages. Two edible species from the genus Agrocybe are reported: Agrocybe broadwayi (Murrill) Dennis and A. elegantior Watling. Full morphological descriptions and illustrations are given for both taxa, as well as an identification key including most related taxa in Agrocybe. Ethnomycological data present basic use of these taxa and suggest that local people recently started using this species for food, particulary A. elegantior.

Abstract : The objective of this study was to contribute to the establishment of mushroom cultivation practices that increase productivity of the mushroom by using locally available materials. These substrates were cut and dipped in cold tap water and drained for 24 hours. Rice bran was added thereto as an additive. The bags were filled at 1 kilogram of substrate, and then pasteurized in steam in a half shaft for 2h30, then cooled for 24 hours and then inoculated with the mother culture. The pouches were incubated until the mycelium has fully colonized the substrate. At the outcome of a study, fruiting technique and substrate type influenced the weight and diameter of pileus. The highest averages in terms of weight were obtained on the technique of casing and the bean vines based substrate while the lowest average was obtained on the shelf. Effects due to strains were not significant.
