Assessing the toxicity level of some useful mushrooms of Burkina Faso (West Africa)

Abstract

Objective: The goal of this study is to evaluate the potential risks of intoxication following the ingestion of wild mushrooms. Methodology and results: This study was carried out on four different species of wild mushrooms including two edible species Chlorophyllum cf. molybdites and Phlebopus sudanicus and two medicinal ones, Ganoderma lucidum and Phellinus pachyphloeus. These species were analyzed on their acute toxicity and their LD50 were calculated based on dry material. The fresh mushroom weights equivalent to the threshold of the LD50 was also evaluated. The fungal species LD50 were 695.62 mg/kg; 679.09 mg/kg; 395.19 mg/kg and 1070.79 mg/kg for P. sudanicus, C. cf. molybdites, G. lucidum and P. pachyphloeus respectively. By comparing these values to the scale of toxicity from Hodge and Sterner, the extracts of P. sudanicus, C. cf. molybdites and P. pachyphloeus are classified among the substances slightly toxic while G lucidum is classified like toxic substance. The fresh mushrooms values equivalent to the lyophilized used for the species were 2.47 kg; 3.67 kg; 1.22 kg and 7.96 kg respectively for P. sudanicus, C. cf. molybdites, G. lucidum and P. Pachyphloeus. Conclusion and application of results: By taking a minimum of precautions, these species could be developed on the nutritional and therapeutic level.However, it is necessary to undertake toxicity study on the fresh material and by oral way, form of administration generally recommended by the tradi-therapeutists.

New records and barcode sequence data of wood-inhabiting polypores in Benin with notes on their phylogenetic placements and distribution

“…Distribution : Widespread in Africa ( Ryvarden & Johansen 1980 ). In West Africa, known from Nigeria, Sierra Leone, Burkina Faso and Senegal ( Guissou et al 2008 , 2015 , Kane & Courtecuisse 2013 ). First record in Benin.…”

Taxonomical study of the genus Amanita from Western Burkina Faso

“…Up to now, most taxonomic research on fungi in Burkina Faso has focused on Russulaceae (Sanon et al, 2014;Sanon, 2015) scleroderms (Sanon et al, 2009; and in general (Guissou, 2005;Guissou et al, 2015Guissou et al, , 2008Bicaba, 2013) in the western, central plateau, central and central regions and the discoveries of amanite species in the cascade region suggest that further studies are needed in other regions of the country with different mycorrhizal hosts and ecology.…”
