If you think you might know what this black, crusty substance is, please go to my blog, scroll down to “Comments” and enter your guess as to what it is and how it got there. Answer revealed tomorrow. (Hint: It is not a gall, and it was found on a Speckled Alder branch.)

Black knot disease, caused by a fungus.

It looks like frass, possibly aphids?

Smut… although smut likes the grass family. Could it have been passed along from an herbivore that had contact with a grass, then investigated whether the alder was yummy as well?

Can you please clarify a group question: Do the seeds pop on witch hazel after the flowering occurs, the same fall, or the following year?

Hi Pam, The seeds are expelled the following year…see https://naturallycuriouswithmaryholland.wordpress.com/2013/10/11/witch-hazel-flowering-and-dispersing-last-years-seeds/ .

I don’t know the name but it is a growth on birch trees that is collected and used in teas, etc. for health and medicinal purposes

I have seen this since I was knee high to a grass hopper while exploring the woods, never really had a clue as to what it was, perhaps a fungus of some kind?
October 19, 2016 at 8:33 am
Have seen this before, but can’t remember the cause. Aphids?
October 19, 2016 at 8:35 am
It’s not Chaga. I’m pretty certain of that.

Black Knot?
October 19, 2016 at 8:47 am
Looks like black knot or a similar fungus.
October 19, 2016 at 8:51 am
Possibly black knot?

A chaga mushroom! They grow mostly on birch around here, but since alder is in the same family, you can sometimes find it on alder too.
October 19, 2016 at 9:35 am
That looks like the fungus that feeds off aphids’ honeydew.

Since you state that it was found on speckled alder, and it’s not a gall, I wonder if it’s something left by the woolly alder aphid (I think that’s what it’s called, and I’m resisting Googling for answers until after I’ve posted my guess). Perhaps the aphid “wool” gets crusty when it ages? After the aphids die? The “wool” is frass or some other type of exudate from the creature.

This is the remainders of hatched moth eggs, on a tree branch.

My guess is Clinker Polypore, Polyporaceae Aphyllophorales.
October 19, 2016 at 10:27 am
Some kind of fungus? Looks sort of powdery/sooty, like mold growing over a dried egg case.
October 19, 2016 at 10:36 am
Wooly aphid?
October 19, 2016 at 11:18 am
It looks like that black, tarry fungus that appears on fruit trees, only sort of dried out.

Does it have something to do with ants farming aphids?

I think this is Apiosporina morbosa, or black knot, a parasitic fungus.
