Valencia Lopez Francisco JavierHola colegasEstoi interesado en este articulo, Agn

On a decorticated branch of Fraxinus I found a white colony of hypho's
Witn the microscope I saw synnemata of 400x17oµ and hyaline conidia of about 22x15µ. Conidia seemed to be solitary.Conidiophores were subhyaline and not markedly branched.Hyphae were 2µ thick.
Could it be Pachnocybe albida?
Why not Aegerita candida, the conidial stage of Bulbillomyces farinosus?
I think you are right with Pachnocybe albida, the spore size fits to my find and also the thick-walled hyphae I think to see on your pictures.
Could you see a stem, because it is hard to recognize on your photo.
Here is my find to compare, it was determined by Keith Seifert and cultivated and sequenced by Walter Gams:

best regards,

Thank you very much Thorben.The red coloured part in picture 4 should be the stem.
By the way, nice macroscopic pictures on pilzforum
