Hyphodiscus spec. - smaragdinus? (viridipilosus) from Italy
Lothar Krieglsteiner, 01-08-2024 17:34
Lothar Krieglsteiner... found 21.6.24, growing on a very thin peace of plant material, likely a very thin woody twig. First I thought it would be Teucrium chamaedrys because the piece was lying between remains of this plant on a small rock in a valley, on calcareous soil, montaneous.
The minute spores with mostly tow conspicuous oil drops I measured about 3,5-5/1,5-2 µm. The asci bear croziers and were found to be iodine-negativ. The brown excipulum is angularis-(primatica) and the hairs are brown and knobby.
With Zottos key I end at H. viridipilosus which I later read is a synonym of H. smaragdinus.
Can this be confirmed?
Best regards, Lothar

Hello Angelo,
thank you for your proposal.
I knew Unguiculariopsis (for instance I found U. rehmii at the same tour) only with strongly curved hairs by now - but surely my knowledge is far from being complete.
In Index of Fungi there is no U. castanea and when I search in ascofrance I am lead to U. lettaui. This I compared and think it isn`t - it has strongly curved hairs and grows on lichens (what my specimen doesn`t).
Back to U. castanea. Can you tell me where I find more about this?
Best regards, Lothar

Check Dasyscyphus castaneus.

"Dasyscyphus" castaneus
Hello Angelo,
thank you very much again.
Yes, this seems to fit well - I looked here:
http://www.ascofrance.fr/search_recolte/3842
Coincidence: on my substrate it was also growing together with a Stictis spec.!
Best regards, Lothar

"Das." castaneus actually belongs like typical Unguiculariopsis spp. in Cordieritidaceae and is, like those, fungicolous, there is always Stictis present.
