Page number:846 
Remarks (internal):Entoloma luteobasis is fairly well characterized by the dark pileus and stipe, the slight to distinct yellow tinge in the base of the stipe, and the small spores. The collection made in Italy slightly deviates from the type in the warmer brown colour of the pileus, and less distinct, lemon yellow tinge in the stipe base. Entoloma griseopruinatum has darker lamellae and larger, more pronouncedly angled spores, and is supposed to be related to E. griseoluridum.
