I’m not a mycologist (though I’m quite fond of lichens), but when a really striking fructification appears beside the trail, I’m eager to know more about it. Recently at Deer Creek Hills Preserve in eastern Sacramento County, a good variety of mycological activity could be found on the rotting wood of fallen old blue oak trees.
Turkey tail fungus (Trametes versicolor) on a fallen blue oak
A closer view of Turkey tail fungus
Resembling turkey tail in shape, but with a fuzzy white surface, is (I think)
Hairy bracket fungus (Trametes hirsuta), also on a fallen blue oak.
This common and colorful slime mold (Fuligo septica) has a
colorful common name … “Dog vomit.”
A Rock-shield lichen, Xanthoparmelia sp.
Another large Xanthoparmelia—perhaps a different species that
lacks the large apothecia seen in the previous photo.
Crustose lichens—I won’t try to guess who—almost completely cover the “tombstone rocks,” the nearly-vertical fins of Cretaceous slate, protruding from some of these hills.
