Morphological characteristics of wild and cultivated Ganoderma subincrustatum from Sonora, Mexico

Abstract

Background: Ganoderma is a complex genus with high morphological variability. Ganoderma subincrustatum is a common parasite and saprophytic species, and its circumscription is doubtful for some authors. The aim of this study was to analyze the morphological variability of wild and cultivated specimens of G. subincrustatum.Methods: Ganoderma subincrustatum strain was isolated from a peach orchard in La Costa de Hermosillo, Sonora. The strain was cultivated on vineyard pruning wastes under low and high illumination. Wild and cultivated basidiomata were macro- and microscopically characterized and compared.Results and conclusions: Ganoderma subincrustarum is recorded for the first time from Sonoran mycobiota. Basidiomata color, size and shape were different between wild and cultivated under low and high illumination. High lux condition caused antler shape fruiting bodies. Wild and cultivated specimens showed the same type of context, similar shape of pileipellis cells and basidiospores, but spores were larger in wild specimens.
