Descolea indoquercina sp. nov. from India is described and illustrated based on morphological and phylogenetic inference. It is characterized by medium to large basidiomata, dark olivaceous brown to dark brown, convex to plano-convex pileus with warts on surface; amygdaliform to limoniform, coarsely verrucose basidiospores, presence of pleuromacrocystidia and hymeniform type of pileipellis. In addition, D. flavoannulata (Lj. N. Vassiljeva) E. Horak is reported and described first time from India in the present communication. Both taxa are presented with detailed descriptions, field and microscopic photographs, illustrations, SEM images of basidiospores, nrITS based molecular phylogeny and comparisons with similar species.
