Small whitish cups on wood - Hymenoscyphus?
Lepista Zacarias, 14-11-2021 17:27
Hi everybody,

In a recent field trip to the Park in Monsanto, Lisbon, Portugal, I found some very small white (at the time) cups on wood remnants. Meanwhile, they change a bit the coloration and got some light yellowish coloration as in the photo attached.
Making the microscopy, the immaturity was confirmed, since only one free spore was found, with dimensions 21.19 x 6.44 µm, and many were still forming inside the asci. The features observed recall me that of some Hymenoscyphus that I found before, but this is new to me.
Can any of you say something more concrete? I upload some photos with details.
Thanks in advance,
zaca.

I think this is a Tatraea. Difficult to say something about the species.

Re : Small whitish cups on wood - Hymenoscyphus?
Thanks, Zotto, for your prompt and clear identification. I have one apothecium left, so I will try to see the mature spores. Any particular reference to this genus?
Kind regards,
zaca

Here : Baral, H.O.; Galán, R.; Krisai–Greilhuber, I.; Mato?ec, N.; Palmer, J.T. (1999). Tatraea dumbirensis, new records of a rare leotialean discomycete in Europe. – Österr. Z. Pilzk. 8: 71–82.

T. dumbirensis has curved spores. But there exist also straight-spored collections, the taxonomy is not yet worked out.
