Re : Lachnum (?) on shells of Fagus nuts
This reminds me of my Lachnum gemmarum on bud scales of Fagus sylvatica in Europe, characterized by hair tips being never inflated, except that the spores are in your collection much wider and the asci larger.
Which Fagus species is it here and is it the inner side of the cupules or of the seed scales?

Re : Lachnum (?) on shells of Fagus nuts
Hello Zotto, and thank you for your help! The tree in question is Fagus grandifolia. I believe the substrate is the seed scales--it is the smooth inner shell of the fruits.
Is there any literature on Lachnum in North America that I can refer to?

Re : Lachnum (?) on shells of Fagus nuts
I have no idea about Lachnum in America.
So you mean the thin brown shell of the triangular seeds .
