Tomentella badioincrustata and T. papuae are described as new species from Papua New Guinea. Tomentella badioincrustata is characterized by the presence of dimitic, slightly differentiated rhizomorphs with smooth chlamydospores (18-25 μm × 18-20 μm) on their surface, large incrusted subicular (up to 10 μm broad) and subhymenial hyphae (up to 7 μm broad), and irregularly globose to ellipsoid (in frontal view), light brown basidiospores (6-8 μm × 6-7 μm). In addition to chlamydospores, the presence of red-brown pigments on subicular and subhymenial hyphae and the amyloid reaction of some subicular, subhymenial and young basidia are typical features of T. badioincrustata. Tomentella papuae has thick-walled, smooth subicular hyphae (up to 8 μm diameter) and triangular to lobed, light brown basidiospores of 5-8 μm × 5-6 μm. T. badioincrustata was compared in detail with the similar species T. subamyloidea, while T. papuae was contrasted with the similar species T. atrorubra and T. coerulea.
