This is my first microscopy of a specimen in the Genus Protoblastenia (assuming that the genus is correct). Here are some of the features observed:
- Hymenium hialine, Epithecium brown with granular material dissolving in K, Hypothecium hialine, Exciple poor developed;
- Spores hialine with a big perispore, subglobose with average dimensions of 6.8 × 6 µm (N=20)

Looking to the small, hyaline and subglobose spores, there is only one choice in the Bristish Flora: Protoblastenia cyclospora; All the other species in this genus considered there have ellipsoid spores.
