I do not think the collection is mixed. The stipe of the little mushroom in image 4 was connected to the stipe of the mushroom in image 2. This is shown in the additional image what has been uploaded. Also see the added image which shows white cotton like material between the gills. This is the same white cotton like veil shown in image 4

Multiple species? Mixed collection?

Fourth photo shows white gills. Cortinarius should not have white gills.
