A. biennis A. chocoensis A. roseus Abortiporus is a genus of fungi in the family Meruliaceae.

[4] Species in the genus grow on the wood of hardwoods and conifers, either alone or around the stumps and living trees.

It causes a white rot in dead wood and a white trunk rot in living wood.

The genus was circumscribed in 1904 by William Alphonso Murrill.

[5] The generic name is derived from the Latin abortus (arrested development of any organ) and the Ancient Greek πόρος (pore).
