The Ganoderma thread!

Seen a gano higher than that on the vet beeches i've posted pics of on here somewhere

 

Sent from Rob's GalaxySII

this gano whilst not a complete surprise is higher than any ive seen to date. huge implications for limb failures with this scenario

 

This G. lipsiense was 8 metres high on the trunk of a 100+ years old bifurcated beech. It was 60 cm in diameter and turned out to be completely hollow, when several years after the upper right half of the combined trees had split off (see first photo), the top of the other half also came down (see second photo). Perennial Gano's of this size "empty" or recycle the sterile inside (trama) of their FB's to "loose weight" and form new fertile pore layers from.

At the base of the trunk were several larger and some small perennial brackets of G. lipsiense, of which the mycelium was competing with K. deusta, which had colonized most of the right half of the trunk and was defending its territory effectively.

The first photo shows the already receding tube layer, which is an indication of the lack of intact wood to decay and gather energy from.

The second photo shows the remaining lower part of the trunk covered with teleomorphs of K. deusta.

gerrit, when you say teleomorphs is that different to the white grey anamorphs? or the same thing? and what is the black crust? is this stygma?

1. when you say teleomorphs is that different to the white grey anamorphs?

2. what is the black crust? is this stigma?

 

1. Yes, the black teleomorphs produce ascospores and the grey anamorphs conidiospores.

2. Part of it, which is on or attached to the bark, is K. deusta, and part of it, which shows itself after the bark falls off, is the pioneer saprotrophic Diatrype stigma decomposing (soft rot) the dead cambium and the top layer of the dead sapwood.

Correction, it's the other way around. Diatrype stigma mostly fruits on the bark and falls off with the bark, K. deusta breaks through the bark and fruits on the bark and/or on the cambium or sapwood.

Some examples of Ganoderma lipsiense on beech.

The first photo is of an old bracket forming smaller wavy brackets at the edge of the old FB.

The following two photo's are of the impressive number (and size) of perennial brackets formed on the remains of an old beech., which clearly shows, that G. lipsiense is a necrotrophic parasite.

Thanks gerrit, that was the last word association i needed to get that right in my head, so G. australe is what we term a Biotrophic prefering live tissues and fading on death of the host, whereas g, applanatum thrives on the dead remains of its host hence the necro/deadwood aspect:thumbup1:

Tony,

You'll see all of these trees, including the Liriodendron, and many more with all kinds of perennial bracket fungi, including Phellinus robustus, when we visit some of the estates and forests or woodlands, I've monitored and documented over more then 15 years, during your short stay in my region coming Oktober .

which clearly shows, that G. lipsiense is a necrotrophic parasite.

 

Another example of G. lipsiense as a facultative parasite can be seen in the pictures of the dead remains of this Tilia, which once was standing on a no longer used old church yard in full sight of the window of a class of my old primary school, the tree in which' crown sometimes a Golden Oriolus was singing.

Some 15 years ago it fell because of a massive decay caused by K. deusta and G. lipsiense, of which one perennial bracket (last photo) still is forming new tube layers, while all other brackets (photo 2/3) have stopped reproducing.

Note how the white and soft rotted wood now has become a substrate for an oak seedling and some seedlings of plants, including Winter Purslane.

last week I found this recently fractured Quercus rubra (during the storm which took 5 lives on the Pukkelpop festival in Belgium). On the stem base there were fruiting bodies of Ganoderma applanatum, but the fracture was 4m higher. On the broken stem I found one small FB, more spherical. Would this also be G. applanatum or maybe another Gano? I did not having a knife, so couldn't take a sample to check the 'flesh'. The fracture looks like there was a hollow (maybe a woodpecker hole).
