Re : asco on Andreaea rupestris
Very interesting as bryophilous fungi are very rarely reported on Andreaea species. This reminds me of Myxophora due to spore shape and appendages, but I have not seen anything with those types of spores on bryophytes.

The main thing that comes to mind was a collection of a lichenicolous Myxophora a few years ago with similar spore shape and appendages. There is one Myxophora known from dead bryophytes, M. amerospora, but your collection looks different as the spores are longer + has appendages.
