Bill Yule thinks it is
Hydnellum concrescens aka
Hydnellum zonatum as shown in George Barron's guide on
page 126. It does not give the spore print color nor information on spore
size and shape. Other guides do not list this specie. The picture on
page 126 shows a mushroom that is paler on the top and does not have the dark
brown teeth that my specimen has.
Growing next to a boulder on a trail.
About 5" in the longest dimension.
Underside. Edge of cap bruises dark
brown.
There are about 8 stems but some are fussed
to each other.
Teeth are up to about 4mm long.
Got a light spore print. It looks
pinkish brown.
Spores are very small. About 4.8
microns and spherical. My microscope could not get a sharp image of the
spores but they
look like they are spiked or warted or irregular shaped.
