This observation is most certainly correctly labeled as Heterobasidion although I can’t speak to species name.

The forested area is a re-plantation effort by the logging company and contains many “second growth” trees and parent trees. Not really a populated area although the small town at the base of the mountain draws irrigation water from the river nearby.

Sorry I cannot be of more help
