The objective of this research was carried out the pathological studies on Lasiodioplodia theobramae the causal agent of gummosis infected African mahogany. The experiment was laid out in a completely randonized design (CRD) with five replicates. The effects of temperature and light and darkness on mycelial growth of L. theobromae were evaluated. The fungus grew from 20-40oC with optimum growth observed at 25-35oC on potato dextrose agars. On the 10th day, mycelial growth at 25-35oC was (15.6mm ± 0.0 - 30.6mm ± 0.05; 18.4mm ± 0.28 - 32.5mm ± 0.10). There was significant effects of light and darkness on the mycelial difference (P> 0.05) on the growth of L. theobromae. It is recommended from this research work that environmental factor such as temperatures; light/darkness significantly supported the growth of Lasiodioplodia theobramae.
