Some fungi species thanks to their antioxidant activities have been found able to protect the liver against toxic substances. There is a lack of data on the antioxidant and the hepatoprotective potential of tropical Africa mushrooms. This study was to assess the antioxidant and protective effects of 22 wild mushrooms from the Noun Division in Camer...

Cytospora is a genus of fungi belonging to the Cytosporaceae family (Sordariomycetes, Ascomycota) considered as a prolific source of specialized metabolites due to their ability to produce diverse secondary metabolites with a broad range of biological activities. Since the first chemical investigation of this genus in the 1980s, further studies hav...

With the increased incidence of Type 2 diabetes worldwide, many therapeutic foods have been used for the reduction of blood glucose amongst which are different varieties of mushrooms. This study determined the effect of Termitomyces le-testui bread on blood glucose reduction. T. le-testui powder was used at up to 30% to replace wheat flour to produ...

Article history: Home gardens are subsistent agricultural production systems consisting of diverse crop plants which are easily accessible and adjacent to homesteads. They sustainably contribute to livelihoods in developing countries. Regarding the modernization in tropical Africa, there are changes in plant composition of urbanizing areas like Tub...

Home gardens are subsistent agricultural production systems consisting of diverse crop plants which are easily accessible and adjacent to homesteads. They sustainably contribute to livelihoods in developing countries. Regarding the modernization in tropical Africa, there are changes in plant composition of urbanizing areas like Tubah Sub-Division,...

Macrolepiota africana is a fungus used as food in Gabon for its culinary properties. However, its nutritional value, mycochemical contents, antioxidant properties and health potential still unknown. The present study investigated the phytochemicals and antioxidant properties of this mushroom species. This chemical screening was followed by a study...

A study of the diversity of gill mushroom was carried out in the primary and secondary forests of Kedjom-keku montane forest, North West region, Cameroon. The purpose of this study was to conduct a comparative study of the specific diversity of fungi collected in these two forest types. Out of the two hundred and fifteen samples collected, there we...

To meet the need for wood in the African savanna zone, forest plantations have been established since the 1930s. Exotic tree species of the genera Pinus and Eucalyptus are the major groups planted in the Western Highlands of Cameroon where they form artificial forests whose mycoflora is not yet documented. This study aimed at comparing the macro-fu...

Lentinus sajor-caju and L. squarrosulus are two important wild edible saprotrophic mushrooms used in tropical Africa. However, they have not yet been commercially cultivated and their uses depend largely on the environmental conditions. In order to improve the management of agricultural wastes and contribute to insure food security in Cameroon, a s...

Termitomyces species are among the most utilised mushrooms in tropical Africa and Asia, with some species having putative medicinal properties. However, data on their diversity, distribution, ethnomycology, biological activities and metabolites are still to be completed, especially in central Africa. During field surveys in the Western Highlands of...

Abstract Fungi are among organisms producing molecules with potential biotechnological applications like ligninolytic enzymes capable of breaking down recalcitrant molecules. Few species especially from tropical Africa have been screened for this purpose. In this study, ligninolytic enzymes of fresh sporophore extracts of 21 wild mushrooms includin...

The milkcap genus Lactifluus is one of the most common ectomycorrhizal genera within Central African rainforests. During a field trip to the Dja Biosphere Reserve in Cameroon, a new Lactifluus species was found. Molecular and morphological analyses indicate that the species belongs to LactifluussectionXerampelini and we formally describe it here as...

Background Termitomyces clypeatus (T. clypeatus) is an edible mushroom specie which grows in various areas in Cameroon. It is indicated by several healers in treatment of several infectionsand is frequently used for this purpose. However, no study has been reported on its antibacterial and immunomodulatory activities which were the aim of this stud...

Background Globally, Termitomyces letestui is used by different communities to treat various illnesses, including bacterial infection, although with limited scientific evidence. The current study aims to assess the immunomodulatory and antibacterial properties of the water extract of a wild mushroom, T. letestui in mice model. Methods The base stu...

This study assesses land cover change of the Koupa Matapit forest gallery, West Cameroon, in relation to anthropogenic factors. Ethnobotanical surveys were conducted to investigate the relationships between the local population and the gallery forest; the spatio-temporal dynamics of the landscapes around the gallery forest were studied from the dia...

During field work in the Noun division of western Cameroon during 2011, 2012, and 2014, several collections of an unknown Lactifluus species were discovered in a gallery forest with Uapaca guineensis. Molecular and morphological research shows that these collections represent a new species, Lactifluus persicinus, which is described in this paper. L...

The ectomycorrhizal milkcap genus Lactifluus is commonly found within Central and West African gallery forests. During field expeditions in Cameroon and Togo, several collections of white Lactifluus species were found, resembling Lactifluus foetens. Molecular and morphological research indicates that these collections belong to two unrelated specie...

This article presents discussions of mushrooms as a source of food, income, as well as medicine among the Bamoun people of the highlands of West Cameroon, where the vegetation is mainly savannah mixed with forest galleries. Like most tribes in tropical Africa, the Bamoun people use a wide range of natural products as mushrooms. This study attempts...

Fungi play major roles in ecosystem processes, but the determinants of fungal diversity and biogeographic patterns remain poorly understood. Using DNA metabarcoding data from hundreds of globally distributed soil samples, we demonstrate that fungal richness is decoupled from plant diversity. The plant-to-fungus richness ratio declines exponentially...

A preliminary inventory of the species belonging to macrofungal genera Lentinus and Panus within the Dja Biosphere Reserve and its periphery brings to light the identification of nine species; Lentinus cladopus, L. retinervis, L. sajor-caju, L. squarrosulus, Panus courtetianus, P. fasciatus, P. similis, P. fulvus and Panus cf. ciliatus. L. retinerv...

Background and aims – Lentinus species are a major component of the agaricoid flora of tropical Africa where fifteen species have been documented with few studies in Cameroon. This work aims to contribute to the taxonomy of the genus Lentinus by describing a putative new species collected in south-western Cameroon. Methods – A unique lentinoid fun...

Inhabitants of the Mount Cameroon region depend on the forest resources of the region for their livelihood, including the diverse use of macrofungi. With the increasing loss of forest due to exploitation and urbanization, they are liable to rapidly lose their indigenous knowledge of the forest resources, especially of mushrooms. An ethnomycological...

Two new forms of Termitomyces striatus are described from Cameroon and a preliminary key to the central African taxa is provided for the first time. T.striatus f. pileatus is characterized by an often subinfundibuliform pileus that is usually squamulose greyish orange when young and cocoa brown or leather brown in age. This new form is additionally...
