patches that can be seen from quite some distance. it is recognized by its short (mostly about cm long) spines, and the fact that the spines hang in rows along delicate branches. under the microscope it features very small, amyloid spores. hericium americanum is similar. it also hangs its spines from...
or conical cap, its yellow to orange colors, and the fact that it does not blacken with age or when bruised. the species was originally described from nebraska, but european mycologists have applied the name to european material, as well, and have apparently relinquished use ofthe species name hygrocybe...
to be more common from the rocky mountains southward, into mexico, than it is in other areas on our continent. it is a very small, gilled mushroom with a distinctively pleated cap (the cap is "sulcate," in mycologese, resulting in the species name sulcata). heliocybe sulcata is found on the decaying...
