Species A. Small black spot spores (hyaline) Me = 5.8 x 1.4 µm
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. “
First pic shows examples yet to ‘open’, the second some ‘open’ with a ‘groove’.
This collection was made July 13th 2014 just north of Newton Stewart NX4068 VC73 (first Scottish record?).
Unless someone wishes to make another suggestion I am inclined to record it as Hymenopsis typhae. Only 24 records in BMS database and 10 on CATE2 (mostly recorded by the Ellis family), neither has a record for Scotland (how fortuitous you mentioned the asco course)!
