Inosperma sorongense Retn. & W.H.Lu, a novel species from Sorong, Southwest Papua, is described based on a suite of unique morphological characteristics and unique phylogenetic placement based on analysis of combined ITS and LSU loci. The morphological features of the novel taxon include medium-sized basidiomata with a reddish-orange convex, umbonate pileus, a reddish-orange stipe with a bulbous base, and large basidiospores. Phylogenetically, Is. sorongense sister to Is. misakaense (Matheny & Watling) Matheny & Esteve-Rav. with well support (MLB = 99%, BPP = 1.0). This study provides a full description of the new species, including field photographs of the basidiomata, micrographs, phylogenetic analysis results, and a comparison with similar taxa.
