Gernot FriebesHi,I'm looking for these three standard references

higher resolution images available at inaturalist.

The fruitbodies I took home were still young and contained mostly oval spores without ornementation of 12-12.5x7.5µ, with 2 large guttules. I also found a few spores with prominent crests. The spores he sent me had also high ridges and had the same size.No reaction with Lugol.
The spore size matches with bicucullata but the paraphyses bent over like a cane what is not describe in Van Vooren 2014. Is Aleuria congrex with rather small spores an option?

Herewith the measurements (without ornamentation) of my three finds of A. cogrex. All measurements were done in water and from mature spores outside the asci!
Best regards,
