Vitus SchäfftleinHello, I found Trochila ilicina on Ilex aquifoliu
Tiny white apothecia on cone

These apothecia were found on the scale of an old Picea abies cone. The largest is just 150 µm across.
Just 3 spores were available for measurement: 6.9-8.2 x 2.2-2.6 µm (a guide but probably unreliable).
Asci: 39-51 x 6.4-9.6 µm. The tips turned blue in Lugol's.
The first micro image is in water, the second in Lugol's.
Any guidance as to where I should be looking, welcome.
Amitiés, Chris

Re : Tiny white apothecia on cone
Are there no hairs? It looks a bit like a Hyaloscypha.

Re : Tiny white apothecia on cone
Definitely no hairs found and I did look carefully.

Re : Tiny white apothecia on cone
On the upper right it looks like a curved thin structure, reminiscent of Hamatocanthoscypha hairs. No idea if I am wrong.

Re : Tiny white apothecia on cone
Many thanks for your thoughts, Zotto.
I had Hamatocanthoscypha laricionis recently on the same substrate, and even the smallest apothecia had a distinct disc shape and the abundant hairs were obvious.
However, I have no experience of other members of this genus.
With so little material to work with, we will probably never know.

Re : Tiny white apothecia on cone
I agree it looks quite different.
