Interesting collection

The spore shape is typical of the species of the O. bufonia clade, but of course the rather small spore size exclude O. bufonia. O. purpurea is a Chinese species belonging to this clade but the spores are smaller. O. bicolor, another Chinese species, is deeply cup-shaped and has spores measuring 10-12 × 5.5-6 µm, this seems close to your collection.
I’m very interested in an examination of a part of this collection.
