Last week I have collected this nice purplish ascomata on old indeterminate leaves (Petasites, Ranunculus?) at 1600 m of altitude. Disc up to 0.7 mm in diameter, margin fimbriate, stipe up to 2 mm.

Re:Rutstroemia cf. venusta
I have seen on Zotto's CD one plate of Rutstroemia cf. venusta and I think could be very close with my collection. What do you think?
Many thanks
Enrique

Re:Rutstroemia cf. venusta
Great collection indeed! Yes, I feel this is absolutely the same as I depicted. "My" specimen was found by Till Lohmeyer on "probably" Petasites.

Re:Rutstroemia cf. venusta
Congratulations, Enrique,
your collection fits in all respects my Bavarian collection from 1981. I have never forgotten this beautiful little cup fungus found on my birthday that year ... The "true" R.venusta Svrcek (see Ceska Myk. 20/1/1966) has considerably bigger spores, but apart from that it's very close.
Where did you find the cute thing geographically? Was it in the Pyrenees?
Best regards
Till

Re:Rutstroemia cf. venusta
Thank you to all.
My collection is made at Somiedo's Natural Park, a very nice region of Asturias (N of Spain).
It's this fungus a microspored form of the true R. venustula?

Re:Rutstroemia cf. venusta
The type of R. venusta was on Helianthemum. I did not compare the image, but the spore size in my database (13-20 x 5.5-7.5 µm) clearly excludes that. Surely a different species. For Petasites I have only Sclerotinia sclerotiorum wit that spore size in my database

OK., Zotto. I will send you my images at higher resolution.
