Poriella Subacida Gen. & Comb Nov. for Perenniporia Subacida (Peck) Donk

Poriella subacida is the name now applied to the fungus long known as Perenniporia subacida (Peck) Donk, reclassified into the genus Poriella.

As a polypore, its fruiting body takes the form typical of this group: a tough, woody growth attached to its wood substrate rather than a soft cap-and-stem mushroom.

Poriella subacida has been recorded across a range that includes forested habitat associated with its Douglas fir hosts. Observation records collected through GBIF are presence data only, reflecting where the fungus has been seen rather than its abundance or the full extent of its range.

Monthly observation counts show a clear rise through spring into summer, peaking in August before declining sharply by November and reaching their lowest point in winter. This pattern suggests the fruiting bodies are most often noticed and recorded during the warmer months, when fungal fruiting and forest visits by observers likely both increase.

1. Poriella subacida was originally described in 1885 by the American mycologist Charles Horton Peck, more than a century before its current classification was settled.
2. The species has been shuffled between genera over time, at one point known as Perenniporia subacida before being placed in Poriella.
3. It belongs to the family Polyporaceae, within the order Polyporales, a group of fungi known for producing tough, pore-bearing fruiting bodies.
