The fruit bodies (i.e., the mushrooms) appear in spring and summer; the bell-shaped caps are generally pale pinkish in colour with red stains, which can also be seen on the stipe and gills.

However, it was widely known for many years as I. patouillardii, as named by Italian mycologist Giacomo Bresadola in 1905 in honour of the French botanist Narcisse Théophile Patouillard.

It is variable in colour, initially white though becoming yellow or brownish with age, and stained with pink-white and red marks or lines.

[3] In Israel, I. erubescens grows under Palestine oak (Quercus calliprinos) and pines, with mushrooms still appearing in periods of little or no rain as they are mycorrhizal.
