Fungal Growth on Black Pine Bark
« on: June 27, 2014, 10:58 PM »
Today I saw four different colors of fungus growing on some black pines.  All were imported from Japan and at least two are confirmed wild-collected.  Has anyone ever seen fungal colonies growing vertically up a section of black pine bark?  I'll post photos tomorrow; two were light brown, one blackish, and one green.  All had white fruiting bodies near the top and all were oddly enough on the "back" of the trees.

The owner has had all the trees for almost two decades and never seen this occur. 

Anyone?

Owen, I've never seen such a thing.  I have had many black pines and have worked with many at the nursery and have never seen this.  Could the fungus be a regional origin?

As a general rule, fungi don't grow on the bark of live, healthy trees. The bark parenchyma produces anti-fungal compounds and, therefore, may be dead where the fungi are. There could be a corresponding 'line' of dead phloem+cambium underneath. The fungi isn't the cause but an after-effect, IMHO. I would begin investigating by digging into a small area of the affected bark, to see what is going on underneith.

During a particularly wet spring I had a string of tiny mushrooms grow up the trunk of a black pine.  (It's the grafting/experiment tree, for those in the know).  It only did it the once, 4-5 years ago maybe, and they lasted for about 2-3 days. 

Other than some creeping moss around the base of several, and some lichen on the bark of older trees I've not had anything else.

Wow, that looks nasty. You sure the tree is from Earth?

The tree was imported from Japan long ago.  Again, first year it has been present on 4 different black pines 3 different colors.....

Is the tissue alive under the bark? You might see if the roots on that side of the trunk are alive.

That is my concern.  It's on a number of different black pines in the collection.  Getting samples tested ASAP.  We'll know whether it's an obligate or facultative saprophyte for starters.  Let's just say I'm concerned.  It didn't live under the bark on the two I did some digging I into.

Chemical aid on the way.  Some old foliage indicates stress but no canker, blight, or
needle cast.  Previous media had soft Akadama used.....  Will update when I get test results from lab. 

Oh, and everyone should come to Nashville July 11-13th for the Southeast Regional Bonsai Expo  ;D.  At Cheekwood Botanical Garden.

I'd think your lab results would be available by now - what was it?

It strikes me as odd that after the USDA quarantine (close to 2 years??) you would have this problem with foreign fungi.

Any way, I for one am quite interested in what it is/was, what your chemical treatment was, and whether your trees have been adversely affected.

Curious (but my name isn't George).
