These basidiocarps are typically egg-shaped (ovoid), almost spherical (subglobose), or shaped like an inverted spinning top (turbinate), with a colour transitioning from white or cream at the base to various shades of reddish grey or rose towards the upper part.

The internal mass, or gleba, is initially solid and dark brown when fresh, becoming lighter and developing a central cavity as it dries.

This gleba contains compartments, or locules, filled with powdery spores and separated by white, fibrous tissue which also turns violet when damaged.

Hosakaea violascens does not produce latex, a milky fluid found in some fungi, and lacks a central support column known as a columella.

[2] The internal structures, including the tramal plate and subhymenium, are part of the support system of the basidiocarp, and are transparent and thin-walled.
