Hello, bonjour.Here is the paper I'm searching for

So looking at it with another friend under a different microscope we tried additional stains. I measured the spores at 13.5 X 9. looking at several of them it appeared that they had spines on the spores that went into a slime layer that surrounded the spore. It also appeared that inside some of the spores there was a figure 8 or prehaps 2 oil drops or septa. Not certain. We also observed that some of the spores had protrusions on each end. There the book he had was the Fungi of Switzerland and there was a Aleuria that had similar looking spores but it looked different and also differed by having a stalk. Could not come up with any better ideas.
I will post spore photos shortly.

I think it's Aleuria aurantia

Il est difficile, à partir de vos photos, de pouvoir apprécier correctement l'ornementation sporale. Si l'ornementation est comme vous l'indiquez, formée d'épines, il ne s'agit alors pas de Aleuria aurantia.
Les Aleuria, contrairement aux Octospora, possèdent des poils hyphoïdes, inférieurs à 200 µm de long, sur l'excipulum. Les apothécies de A. aurantia peuvent être inférieures à 10 mm de diamètre.
La planche 99 de B&K illustre Sowerbyella reynana (Bull. :Fr.) J. Moravec, non une espèce du genre Aleuria.
En annexe une planche montrant les ascospores de A. aurantia.
