A wild mushroom that usually appears only in forests has been grown for the first time on leftover farm material in Nigeria. Researchers at the Federal University of Technology Akure successfully cultivated Lentinus squarrosulus, an edible wild species, using sawdust and cocoa pod husks. The breakthrough could turn agricultural waste into a reliable source of food and income.
A forest fungus finds a new home in sawdust and cocoa husks
Lentinus squarrosulus is a mushroom that Nigerians have long foraged from the wild. It is prized for its taste and nutritional value, but its seasonal and unpredictable growth makes it hard to find. Scientists wanted to see if they could grow it outside the forest, using materials that farmers already have in abundance.
They mixed sawdust with cocoa pod husks, a common waste product from cocoa farming. The mixture was sterilized, inoculated with mushroom spawn, and kept in a controlled environment. Within weeks, the mushrooms fruited successfully. The experiment showed that the species can be cultivated without relying on forest trees.
Why local farmers and families stand to gain
Nigeria produces large amounts of agricultural waste, much of which is burned or left to rot. Cocoa pod husks alone are generated in huge quantities across the country's cocoa growing regions. Using them to grow mushrooms offers a low cost way to produce protein rich food.
The researchers noted that the mushrooms grew well on the waste substrate and required no special equipment. For rural communities, this means a potential new source of nutrition and a product they can sell at local markets. The method also reduces waste and pressure on wild mushroom populations.
What the experiment revealed about the mushroom's potential
The study was led by researchers in the Department of Biology at the Federal University of Technology Akure. They documented the entire cultivation process, from substrate preparation to harvest. The mushrooms reached full maturity in about 30 days, a relatively short cycle that allows for multiple harvests.
Cocoa pod husk based substrates performed particularly well, producing mushrooms with good size and yield. The scientists concluded that this method is viable for small scale and possibly commercial production. They called for further research to optimize the process and test other types of agricultural waste.
This work matters because it connects two pressing needs in Nigeria: managing farm waste and finding reliable food sources. By turning a wild fungus into a cultivated crop, researchers have shown that solutions can come from the most unexpected places, including the leftovers of a cocoa harvest.
