text: # Oligoporus
  
  Oligoporus is a genus of fungi in the family Polyporaceae. The genus was circumscribed by German mycologist Julius Oscar Brefeld in 1888 with Oligoporus farinosus as the type. This species is currently known as Postia rennyi. The genus name combines the Ancient Greek words ὀλίγος ("few") and πόρος ("pore").
  
  Oligoporus species have fruit bodies that are either crust-like or pileate (i.e., with a cap). Species cause a brown rot of wood. The hyphal structure is monomytic, meaning that only generative hyphae are produced. Spores made by Oligoporus fungi are ellipsoid or have a short cylindrical shape.
