from Portugal, on naked soil under Quercus suber above slate-stone. 
When collecting, I strongly thought of Purpureodiscus subisabellinus but hesitated mainly because of the different ecology (I know P.s. in connection with Fraxinus-wood from different findplaces).
Under the microscope it became clear very soon that the collection is not P. subisabellinus. The recherche now led to the paper of Hirsch and his description of P. kreiselii with quite similar characters. Unfortunately, I have no access to the descriptions of P. bananincola (likely not my fungus) and P. luteorosellus - as the latter is a LeGal-species likely from Southern Europe it also could perhaps be a possibility.
I noted clavate paraphyses that are often clustered, eguttulate spores of about 17-21/9,5-11,5 µm, asci with a diffuse iodine reaction at nearly entire length and pleurorhynchous ascus-bases. I also had thought of Pachyella because of the thick ascomata, but I found no gel and no oildrops in the spores (besides the drier ecology).
Who can tell me if P. kreiselii is correct or if P. luteorosellus is perhaps a better choice.
Yours, Lothar
