should be Trochila tini - from Germany

Today we found this discomycete in Stuttgart, on a wall besides a garden. The apothecia were greyish and greenish-yellow when drying.


The asci are without croziers and euamyloid (Calycina-type). The spores are about 9-10/3,5-4 µm, with a lot of oil in large drops when alive. The paraphyses and partly the margo cells contain large yellow vacuolar bodies.


I think there can be no doubt about the determination even if I do not have literature (?) - and in the internet I do not find much.


Can the determination be confirmed by somebody?


Regards from Lothar

Hi Lothar

no doubt, at least if you have it on Viburnum tinus.

But that species has croziers like all Trochilas that I know, and I think I see one on the upper right of your third micro, unsharp but a clear "V".

Strange that TRochila is related to Encoelia furfuracea and Velutarina, at least it has the same greenish-yellowish VBs.

Hi Zotto,


thank you very much - yes, it was on Viburnum tinus (I forgot). I will have a look at the croziers later, I have overlooked them possibly.


Best regards from Lothar


P.S. Do you know of finds in Germany? - and where is T. tini described accurately?


P.S. The yellow-green VBs are very characteristic - yes, I know them from Velutarina, too. I must admit: I never had Encoelia furfuracea under the microscope :-)

An accurate description? What do you expect? ;-)

I think I never saw the original description by Grelet & Crozals 1928. I know the fungus from a sample by Ted Batten from Worcestershire, and I have Enrique's pretty docu from Navarra.

Thank you very much, Zotto!


Thus: possibly first find in Germany?

Re : should be Trochila tini - from Germany
It was a lapsus to say Grelet & Crozals 1928. That is Trochila tami which will more difficult to be found I suspect.
