photo and second are fallen branches over third photo stump. The other black were on the other stump and on this stump no brown was seen, all of this stump have multiple forms, I have some bad photos that I am going to upload, now ordered.
and the black grow on the same host it is also Hypoxylon multiforme whose preferred hosts in Central Europe are birch and alder.
I saw some photos of Alnus glutinosa barks (“Amieiro” for us) and that’s it, so probably it is H. fusca on the 4 photos that you counted.
I saw it in situ but I can’t from pictures ;)
Ok, photos 2 and 3 for me are the violettish ones which I first thought to be Hypoxylon fuscum. You say the last two photos are the same fungus, but they look brownish-reddish supposedly because of artificial light. Let’s say these four pic represent the same mushroom.
The rest is the black one and on it there seems to be a Nectria (now Cosmospora (but don’t blame it on me ;) ) episphaeria.
I do not dare to say more without scope ;)
nothing is easy! My eyes don’t see anything red but the nectria. Ones have shades of light brown (last photos are equal to second photo), others black. It could happen that the only beechs of the place were these, and someone cutted them :). Now, look at the branch and tell me, what tree is it, hum hum? Just kidding.
Often on such stumps there is a great variety of various Pyrenomycetes and similar fungi as well as corticioid ones (mostly on the underside). I’m not familiar with an interplay between Xylaria and Hypoxylon. If you ask me there is none.
detail: the first stump had xylaria too.
From this four species I only know the first. Maybe I have found the other two but not sure.
No hazel and no beech … high probability for the reddish one to be H. howeanum.
Hm, this again would need a scope. But it is not my favorite group of fungi …
Photos 1 to 3 and indoor – one stump
Photos 4 to 6 – another stump near the other.
I saw the trees of the place, and took some photos… ho, it’s easier to take photos on fungi…jesus! There are Poplars, Birch, Laurus, Salix, Oaks, Euclyptus, Mimosa, Pines, corks. No avellana nor beech.
there is Nectria on it.
Okay, if it is birch than the black one is Hypoxylon multiforme.
For me the next ones look violettish and I would have said H. fuscum but I have never seen that on birch.
If it is red like in the latter photos it most probably is Hypoxylon howeanum. But I am not familiar what else there could be in South Europe.
they vary from brown to black. Some have something red on the pores.
I thought it would be H. fragiforme with different stages… they were all on the same place. It’s another cut tree, but I believe it’s a birch.
you have two different species here.
The black from the first pic seems to be a Nemania.
The violet ones, were they on hazel nut? Could be Hypoxylon fuscum.
Not sure if from the other black ones there isn’t even a third species present.
