Observation 76346: Xylodon crustosus (Pers.) Chevall.
When: 2011-09-14
(37.939° -122.6617° )
Herbarium specimen reported

Notes: The sporocarp was probably a meter long and on the underside of a large Douglas-fir log. The general size, shape and color of the fruitbody remind me of the collection from Yosemite that I called X. quercinus.
However this one was on a conifer log, and the spores were smaller 4.7-5.6 X 2.3, and so this is more consistent with the X. crustosus. The spores are really hard to photograph (or see) because they hardly pickup any stain (meltzers or congo red). This is similar to the other collection. The incrusted cystidia in the photo does not fit with the species description of X. crustosum, but after drying I could not find any cystidia, which is consistent with the description. There is no color reaction with KOH.
