Description

''Neolentiporus'' is characterized by medium to large fruit bodies that have stipes and a poroid

hymenium The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in oth ...

l system is dimitic with clamped, irregularly thick-walled generative hyphae that do not react with cresyl-blue stain. The skeletal hyphae are unbranched, thick-walled, and are strongly metachromatic in cresyl-blue.

Spores In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plant ...

, thin-walled, inamyloid, and binucleate. ''Neolentiporus'' causes a brown rot. 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.
