Xeromphalina campanella

The common names of the species include the golden trumpet and the bell Omphalina.

As they mature, the outer part of the cap expands and rises which leaves the center depressed, resembling a navel.

[9] The fruiting occurs in clumps or very dense clusters on decaying logs, stumps, and woody debris of coniferous trees.

[10] Xeromphalina kauffmanii resembles the species, but has a more yellow cap[10] and grows on decaying wood of broad-leaved trees.

[2] Xeromphalina brunneola also resembles the species, but has smaller, narrowly elliptical spores, and differs in odor, taste, and cap color.
