Abstract
Sixteen mushroom species, namely, Agrocybe broawayi, Chlorophyllum molybdits, Coprinus
africanus, Coprinus congregatus, Lentinus subnudules, Lepiota bionata, Plerotus tuber-regium ,
Psathyrella atroumbonata, Termi tomyces microcarpus, Termitomyces robustus, Termitomyces
striatus, Termitomyces species, Tricholoma lobayensis Volvariella esculents, Volvariella
speciosa, and an unidentified species were studied.
Maltose- and glucose-glutamic acid liquid media suported good mycelial growth of the five
species investigated. Some of the species contain various amounts of protein, fats, fiber, and
carbohydrates.
Mycelial growth of the five species investigated was temperature and pH dependent. Minimal
and maximal growth temperatures were 10°C and 40°C respectively for each of the species.
Optimal temperature requirements varied between 25°C and 40°C. The mushroom species grew
best around pH values of 6.5 and 7.0
The greatest amount of protein (>50%) occurred in V. esculenta. Most of the mushrooms
contained the major as well as the trace elements in measureable concentrations. Aluminium
occurred in very high concentrations in all the species tested. Arsenic was virtually absent in all
the mushroom species studied. Alkaloids and tannins were detected in most of the species
tested. Saponins were not detectable in any of the species analysed.
C. molybditis was as good as casein in promoting growth of white albino rats, but it made such
rats extremely excited and aggressive. T. straatus was found to be highly toxic. All the rats that
were fed on a diet containing the mushroom died within 4 days.
P. tuber-regi um and P. atroumbonata were successfully cultivated in the field. C.
congregates and T. lobayensis were cultivated in the laboratory using Blighia sapida and
Terminalia ivorensis (Black Afra) wood chips together with their saw dust
