    Hello,

    I am student at The Evergreen State College (TESC). I found what I believe to be L. megaspora. Looking for any additional insight into this ID.


    Location: TESC Olympia, WA

    Elevation: ~10ft AMSL

    Substrate: Bark - Thuja plicata

    Ecosystem: Second growth forest - mixed dominance. Adjacent shore Salish Sea.

    Notes: Found on the trunk of a Thuja plicata that had fallen onto the beach due to rock-fall.

    Characteristics: Most notable is the barrel/mug-shaped pycnidia with "whipped cream" or "frothy" tops of extruded pycnospores which I attempted to photograph. No apothecia observed. 

    Chemsitry: C-


    Thanks!

    Yes, it looks like you have it. I remember that it was abundant a the end of the Beach Trail on Eld Inlet, when we visited there on field trip with NWL at a recent NW Science meeting at Evergreen.
