Really don’t have a good idea for the ID of this beautifully colored polypore. I’m guessing Trichaptum due to color, but think it might just as well be a Trametes due to clustering habit and angular, non-toothy pores. A small cluster fruiting atop a decayed log. Intense purple-violet of both cap and pores fades to a duller purplish-brown with age. Angular pores, 1-2/mm. Tiny velvety hairs on cap surface.

individual fruit bodies each measure 4 cm. or less. This was a very fresh specimen. I’m wondering if the pores (which break up into teeth – Arora) had not aged enough to become toothy.

Thanks for sharing your comment, Danny. It is quite curious.

I am surprised that something this large and this uniquely colored has not been recognized by anyone on MO yet. I’ll remain hopeful=)

I just collected some Daedaleopsis confragosa today off a maple log in Portland, Maine, and some of the younger fruiting bodies had a distinct band of purple in the pores. I am not accustomed to seeing this color on any polypores other than Trichaptum. I doubt this fungus is Trichaptum for the reasons you state, but also on account of sheer size.
