[1] Neolentiporus is characterized by medium to large fruit bodies that have stipes and a poroid hymenium on the cap underside.
The caps are circular to fan-shaped with a scaly surface, and have an off-centre or lateral stipe that sometimes is reduced to a short, robust umbo.
The hyphal system is dimitic with clamped, irregularly thick-walled generative hyphae that do not react with cresyl-blue stain.
[1] Molecular phylogenetic analysis shows Neolentiporus to be closely related to Buglossoporus.
This latter genus, however, has a monomitic hyphal system in the trama, and lacks metachromatic skeletal hyphae.
