Agaricus julius
Species of fungus
Agaricus julius, commonly known as the emperor or the prince, is a basidiomycete fungus of the genus Agaricus, closely related to Agaricus augustus.
Taxonomy
Agaricus julius was first described by American mycologist Richard W. Kerrigan in 2016.
Description
The cap is 5–15 cm (2–6 in) wide, sometimes larger. The appearance of this mushroom is very similar to the store-bought portobello mushroom. It stains slightly yellow where damaged or nicked. The cap is light brown with a scaled pattern. When young, it has a cottony veil covering the gills. The mushroom can become quite large as the cap opens. The gills are initially pinkish-gray to pink when young, then turning brown at maturity; crowded; not attached to the stipe.
The stipe is 2–3 cm (3⁄4–1+1⁄4 in) wide, and 5–15 cm (2–6 in) long.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Agaricus julius”, the useful work is to connect “species of fungus” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jan 6, 2026. The linked authority identifier is Q107472733. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2016.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
