This species has been treated as C. langei by Vesterholt (1990, 1991) and Soop (1998), and you could say that there has been build a scandinavian tradition of calling this species C. langei.

It has a pale yellowish brown cap (often with patches of universal veil), pale gills and a broadly marginate bulb. The spores has the caracteristic net-like ornamentation of section Callochroi, and no hypoderm is present. It grows in association with beech (Fagus) on calcareus soils.

It may be confused with especially: C. saporatus, which is bigger and brown, C. caesiocortinatus, which has round spores, other pale species near C. callochrous (i.e. C. callochrous var parvus, which is smaller and more slender), and C. polymorphus, which has an unmarginate bulb.

Another interpretation of the name C. langei can be seen here.
