Growing from Odontotermes mound also side Boscia Foetida. Species of Termitomyces but don’t have a key yet to determine which one.
Other option based on this key could ne T. Schimperi
(https://www.mycokey.com/BurkinaFaso/Termitomyces.htm), actually no, not the correct geographical range so T. Reticulatus seems correct.
