Venturioscypha/Venturiocistella
Karl Soler Kinnerbäck, 21-05-2024 17:48
Hi all,

Could this be Venturioscypha or Venturiocistella? Found on pinus branch in Örebro, central Sweden, 2024-05-09. 

Spores hyaline, aseptate, 10-13 x 2-3, at least a few with visible appendages

Asci ~30 x 8-9, IKI-

Hairs up to 100 x 4, I find it hard to distinguish different types.

I only have a few specimens but if more info/pictures are required for determination I will go back. 

Best regards
Karl

Re : Venturioscypha/Venturiocistella
To me this looks much like Venturioscypha nigropila, although I never saw the dots on the hirs so distinct. You do not have the fungus fresh? Asci and spores n water it would be much easier to comment.

Re : Venturioscypha/Venturiocistella
Hi Zotto!

The pictures were taken the same day as the collection. Here are some additional photos of asci in water from the fresh material.

Re : Venturioscypha/Venturiocistella
The first pic is much better, I see the oil drops in the spores as I know them from this species. You need prepare cautiously, no pressure! Fungal cells are very sensitive.

Re : Venturioscypha/Venturiocistella
Ok I will keep that in mind. Should I make another, better prep or do you feel that this is enough to confirm Venturioscypha nigropila?

Re : Venturioscypha/Venturiocistella
I think it is enough. The wart-like structures I really wonder why thy are so distinct. These pics were with il immersion and in water?
Karl Soler Kinnerbäck, 22-05-2024 19:27
Re : Venturioscypha/Venturiocistella
yes the hairs are with 100x oil immersion in water. Thanks alot for the conf Zotto!
