Species B. Larger black spot spores (dark) Me = 12.9 x 3.5 µm

Below is a comment from CA – thanks.

“However, the larger one is a bit more distinctive in having pigmented spores and looks like it might be an Anthostomella. I had a look in Ellis and Ellis and it mentions A. limitata but the spore shape looks wrong. You’re then have the task of checking all the other Anthostomellas (or allied genera) to see which one fits best.

The smaller one looks like it might be a Coelomycete rather than an Ascomycete; in other words, an asexual fungus with conidia. However, haven’t got any further than this. “
