Calonarius saxamontanus

The cap of Calonarius saxamontanus is yellowish to brownish. It starts out round or convex, and becomes broadly convex or flat. It is about 3-7 centimeters in diameter.^[2] The stipe is about 4-4.8 centimeters long and 1.7-2.2 centimeters wide. It is yellowish to brownish in color and sometimes bulbous at the base.^[3] The gills start out yellow and become brown as the mushroom gets older. They can be adnate or decurrent. A thick, voluminous cortina covers the gills, making the gills only visible if the mushroom is old or the cortina is torn. The spore print is rusty brown.^[2]

Calonarius saxamontanus and several other species appear to be in the process of evolving into secotioid fungi. They still release their spores, but many are caught by the cortina.^[2]

Calonarius saxamontanus is found in dry coniferous forests in the eastern regions of the Pacific Northwest.^[2] It is found about 4,500 feet above sea level, and grows under fir and pine trees.^[4] It fruits during spring and early summer.^[2]
