Hello.A cerebriform ascomycete sprouting scattered

Yesterday I found a Periconia on a dead Aesculus leaf, near Belfort (north east of France, altitude of 400m). I need help with identification.
Description :
- solitary conidiophores, with only 3 examples scattered on a dead leaf of Aesculus.
- Foot approximately 400 µm long, with three septa. Foot width of 10 to 15µm depending on location. Slight enlargement of the foot at the apex, at the level of the cluster of conidia.
- the cluster of conidia has a diameter of 30 to 45 µm. It is fixed unilaterally. I noticed this element when varying the focus of the microscope. See on photo number two.
- the conidia are slightly warty (hardly visible in my photos), yellow-brown and measure 6 to 7µm in diameter.
These elements remind me of Periconia britannica described by Ellis (1976), because the cluster of conidia is fixed laterally and the conidia are small in diameter.
What do you think ?
Furthermore, does anyone have a key to Periconia to recommend to me?
Charles
