2015-07-18-9428 Julella vitrispora (?)
Lepista Zacarias, 24-07-2015 12:28
Hi everyone,

Last year I found an ammount of specimens, which I classified as Julella vitrispora.

Now, in a different habitat, I found another location with many specimens. I think that is it again J. vitrispora, but I would like to hear your opinion. I attach some data on these specimens, the reference used for classification and a file with photos of one specimen and from the corresponding microscopy.

Thanks in advance,
zaca
