Abstract- This study focused on the identification of fungi species in fresh and rotten yam tubers by inoculating the samples on Potato Dextrose Agar and fungi staining. 16 rotten and 16 fresh yam samples were collected from four different locations, and four (4) different fungi species were isolated and identified. These include Aspergillusniger, Botryodiplodiatheobromae, Penicilliumspp, and Yeast. With Aspergillusspp having the highest percentage occurrence in fresh (50%) and rotten yam samples (81.25%) followed by Botryodiplodiatheobromae, 62.5% and 25% in rotten and fresh yams respectively. Penicilliumspp has 43.7% and 18.75 in rotten and fresh yam samples, with Yeast showing the least percentage occurrence with 62.5% in rotten and 6.25% in fresh yam samples. The presence of these organisms in yam could lead to serious health matters when consumed, therefore should be prevented by proper storage under minimum temperature.
