Agrocybe putaminum

''Agrocybe putaminum'', commonly known as the mulch fieldcap, is a species of agaric fungus in the family Strophariaceae in the “Agrocybe sororia'' complex. Described as new to science in 1913, it is found in Asia, Australia, Europe, and western North America, where it grows in parks, gardens, and roadsides in woodchip mulch. Fruitbodies of the fungus have a dull brownish-orange cap with a matte texture, a grooved stipe, and a bitter, mealy taste.
