Under these plants grow loose mushrooms that in Congolese villages do not consume as their meats change color to the manipulation and to the cut.
It could be a Phlebopus sudanicus or a P.portentosus (which is Asian) or another Phlebopus still unknow
The plant seems to me to be a species of acacia but I do not know exactly the Congolese or African name and the Latin name.
No Congolese University has answered me.
Thanks.
