Very small (~0,5 mm) white ascos, found yesterday

This was discovered by chance, yesterday, as I was harvesting a specimen of Trichia lutescens (Myxo) on bark of Salix aurita on a branch in the air at about 2 m height. The specimen of Trichia was collected in 14.11.2019, in National Park Eifel, Germany, "Fuhrtsbachtal", altitude about 550 m NN, younger Betuletum pubescentis with Salix aurita
With the key of Zotto I end at Propolis rubella, and I find it quite fitting, including the host. The spores are about 20-25/4,5-5,5 µm.
As I look in Index Fungorum I find rubella a synonym of P. faginea (!).
Can I consider my find P. rubella?
Best regards, Lothar
I can only agree. The narrow spores are quite characteristic, as is the tendency to pale reddish hymenia. Marketa once made a poster with this and other Propoli, but she never published on them. Her images of the lectotype are in my rubella folder. I remember P tumidula as a synonym.
Zotto
vielen Dank, Zotto!
Herzliche Grüße von Lothar
