Fungi on lichen (Cladonia gracilis)
François Bartholomeeusen, 09-10-2019 22:13
Dear forum members,

I have no experience with lichens, let alone with mushrooms on lichens!

On the podetia of Cladonia gracilis (not 100% sure of the determination) I found brown/black ascomata (diameter: 286-317 µm). After making five preparations I didn't succeed in finding free spores and the microscopic pictures are anything but excellent.
No reaction in Melzer, texture and/or paraphyse with brown pigments.
Can someone help me with the identification?

Using a key I found in the publication of Mikhail P. Zhurbenko and Raquel Pino-Bodas (A revision of lichenicolous fungi growing on Cladonia ...) I determine the apothecia as Brackelia lunkei. The podetia are bleached in the places where the ascomata occur. Could this fungi be parasitic?
Am I right or am I completely mistaken? Thank you in advance for all your help.

François Bartholomeeusen

Hi Francois

I hear the name Brackelia the first time, and I do not have the paper of 2017. I would be glad you could send me.

Hi Zotto,

No problem, attached to the article maybe other persons are also interested.
Kind regards,

Re : Fungi on lichen (Cladonia gracilis)
Thanks! There is indeed some similarity, but it is not easy to compare because the type was described in dead state.  But it coud well be this species. Where did you collect it?

Your pics lack a scale, while the statement 1000x is useless for me when I want to measure.

Re : Fungi on lichen (Cladonia gracilis)
Your right, I have to find a way to work out a scale...

I collected the Cladonia gracilis on 27 september 2019 in Belgium, 2460 Kasterlee, in the nature reserve "Grote Heide"  which is a part of a "sleeping" land dune "Kempense Heuvelrug".
