Observation 76036: Cerrena unicolor (Bull.) Murrill

When: 2011-08-24

Collection location: Sewickley Heights Park, Allegheny Co., Pennsylvania, USA [Click for map]

Who: Ann B. (Ann F. Berger)

No specimen available

This fungus looks as if it should be growing on a coral reef in the ocean, but is growing on a log.
The elongated white pores, growth on dead wood, leathery to stiff tomentose caps match with I. lacteus, but the colored zonation and shaping of the caps into wavy ridges and fluted turrets is distinctive.

It is a weird growth form, maybe because the log rolled as it was growing.
It’s not green because it’s to young for algae to grow on it.

I appreciate your input, Noah

I would not have thought of Cerrena, as this fungus seems to be upside down, if you will. While most pic’s of Cerrena show a bracket-form greenish cap with a labyrinthine pore surface, this one is resupinate, then grows upward into these turrets and ridges. Why are there two such different forms?
