The viscous top of cap and brown color suggest that this mushroom is in the T. pessundatum group. but species determination is tentative. Trichoderma ustale is associated with hardwoods, while conifers predominate at Capilano. The GenBank sequence for T. muricatum matches our sequence well through the ITS1 region. The notes from the fresh specimens suggest that the color was originally reddish brown rather than the yellow brown that appears on the photo.
