When: 2008-12-09

Collection location: Bon Tempe Reservoir, Marin Co., California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

Initially I thought these would be easy to identify. Now I can’t even get them to genus although they appear to be some type of small polypore. They do have small pores on the underside of the tough but pliant branches. The largest was only about 5.0 cm across and 1.5 cm tall. They were growing on an embankment, possibly on roots, on the edge of a mixed woods of fir, oak, and madrone. The spores were probably white, and approx.4.0-5.4 X 2.3-3.3 microns. There wasn’t any obvious ornamentation. In looking closely at the photos there seemed to be some kind of round, reddish, flower-like object growing on/in a few of the branches. I hadn’t noticed them during my initial examination.
