Damage, symptoms and biology

Humicolous species with an orange-yellow cap that is slightly umbonate and covered with tiny brown scales, especially near the margin. The cap measures 3 to 10 cm in diameter and has a viscous surface. The yellow flesh reddens when exposed to the air and does not have a distinctive odour. This species does not have gills, but rather yellowish brown tubes, which are more or less decurrent, fairly large (2 mm in diameter) and angular. The stem is the same colour as the cap, with tiny brownish glandular dots. This species produces cinnamon-brown spores.
