Hi!
I'm new here and this is my first post :)
I have found a black fungus in Lisbon, Portugal, and I'd like ask if someone could point me to what it could be.
Cheers
Gonçalo

Re : Help with a black fungus
Hi
good would be to tell us the name of the tree. The resolution is a bit low, are these stipitate apothecia?
Finally, without microscopy we can hardly give it a name.

Re : Help with a black fungus
Hi
The tree is a Viburnum tinus.
The ASCOfrance did not allow me to upload the photos with the original resolution. I had to use a site to resize them to lower than 150Kb (the first time I did it).
If you have better suggestions of ways to resize the photos without loosing so much resolution, that would be nice.

I don't have a microscope. So if that is a necessity, I'll have to leave at that.
Thanks,
Gonçalo

Re : Help with a black fungus
If you have a image editing program you should be able to cut your images and upload only the part with ascomata, then they appear in higher resolution.
Can you exclude a lichen?

Hello Gonçalo,
larger images can be uploaded as files instead, the size limit is higher for files (I don't know how high exactly, a question for Christian?).
