Please find an image taken below of some Typha with several things growing on it.
For starters, has anyone got any idea what the small black spots (species A) could be?
I have had a look in Ellis and Ellis but not turned up anything that matches. Any help/suggestions appreciated.

Species A: Small black spot Squash x 400

Species A: Small black spot squash x 1000 (unstained)
Species A: Small black spot squash x 1000 (lactophenol blue) – cropped. Hyaline spores Me = 5.8 x 1.4 µm

——————-Species B: LARGER BLACK SPOTS GAVE DARK SPORES BELOW ——————
Species B: The larger black spots produced the following coloured spores – Me = 12.9 x 3.5 µm ; Qe = 3.7. Likewise, any suggestions appreciated.
