The last of springtails! :)

Dicyrtomina sp. infected with Pandora batallata fungi?

Globular springtail infected with conidiobolus coronatus fungus.
I was looking for this species without luck but I only realized now that it was present on the branch...
Observations faites autour du Mont Tendre, la plus haute montagne du Jura suisse.
Growing from a tree. Almost play do like smell
Growing on calcareous rock.
After concluding that Verrucaria baldensis exist here (see https://www.biodiversity4all.org/observations/39119583) it seemed probable, due to its appearance, that this would be Opegrapha rupestris, that is known to live parasitic on Verrucaria baldensis.
However, a quick microscopic analysis showed that the spores are 1-septate and not 3-septate, as is the case of Opegrapha rupestris. Therefore, this must another lichenicolous lichen, not known to me.
Very impressive set of specimens growing on the surrouding walls of the city. The first specimens of this species were observed from this location, some years ago.
Lichens seen on imported fig tree, tropical origin (potted plant).
With Cuphophyllus pratensis, growing inside a fabric tube.
First find on iNaturalist.

First observation of 2024. Birch trees under some amazing Aurora borealis !
On Hawthorn, Crataegus monogyna. These I think are true cilia (not out-turned rhizines as I've encountered before).
