Fibroporia radiculosa

Pycnoporellus alboluteus

Description:

Polypore with no cap; grows directly on the wood surface. Small patches ranging from 2 to 8 inches. Also found under layers of decayed wood that had fallen loose from the log. Golden-orange in color, fading to white at the tips. Pores approximately 0.5 to 1 inch long; large and irregular. Pores become eroded to look like veils or teeth. Fungus is ‘rubbery’ to the touch. Stains red with KOH.

Habitat:

On the ‘underside’ of several decaying pine logs on the north-facing slope to the reservoir.

Notes:

Originally thought to be Pyconoporellus alboluteus. Confirmed as Fibroporia radiculosa by ITS sequencing.

These are small but the 'colonies' can be large. My other spotting of this fungus was more than 1 feet long with 'layers' of veils. From a distance, the first spotting looked like a crust fungus and I almost didn't investigate because I had to climb over several fallen logs and 'wade' through pine needle litter. So glad I made the effort, though.
