Orange disc on Juniperus

Good evening everybody,


In La Ste-Baume in Provence I found some orange discs on Juniperus communis with a hymenium surface appearing granular. The asci were 8-spored and the ascus wall was Melzer positive. Paraphyses were slender and had yellow cristals at the end. Spores measured 11x6µ.


Anyone could help me further?

Hi Marc,

Greetings Peter.

Hallo Peter,


 


Thanks for your reaction.I think you are right. I missed the thallus on examination.


I'll see if I can find the species

Re : Orange disc on Juniperus
I vaguely see the central thick septum and suspect it is a Caloplaca.

Re : Orange disc on Juniperus
Yes, it is Caloplaca s.lat. It was split recently on many smaller genera, and it may well be e.g. Caloplaca (Blastenia) hungarica or still something else. But this is a question for a specialist on Teloschistaceae. Zdenek
