Commonly known as poplar mushroom or velvet pioppino:
MORPHOLOGY
The cap is initially subglobose evolving to extended convex, always brown although in different shades. As it matures, the colour lightens considerably from the centre —which does not vary significantly— towards the perimeter, which eventually turns almost white. The surface of the cuticle is wrinkled, with small fissures, glabrous and frequently cracks due to a lack of moisture in the heat —or cold, as it also dries it out— and to growth. The edge contains some remains of the veil, wavy and notched. Sometimes it cracks with growth.
