The Ganoderma thread!


Recommended Posts

The perennial fruit bodies of G. applanatum have often been confused with those of G. adspersum, but the following characteristics can help to differentiate these species. If the lower surface of the fruit body bears the galls from larvea/emerging fly Agathomyia wankowici, the fungus can be identified as G. applanatum, as it is the only European species of Ganoderma affected (BREITENBACH and KRÄNZLIN, 1986). (though currently there is some discussion on this points validity) I will update! however these examples (below) are clearly g applanatum.

In this image droplets can be seen oozing from ovipositing wounds by the fly, galls will then develope.

Apart from the galls of Agathomyia wankowici on G. lipsiense (= G. applanatum), the only way to make sure you're either dealing with G. lipsiense or G. australe (= G. adspersum) is by looking at the size of the spores (microscope). And a warning : especially on Acer, Aesculus (Anne Frank tree, Amsterdam), Quercus rubra and Tilia, the white rot with selective delignification of G. australe is up to ten times as detrimental to the stability of (the trunk of) the tree as that of G. lipsiense is.

G. applanatum is arguably wholly saprobic, whereas Ganoderma australe has considerable capacity to penetrate healthy sapwood and can even use the barrier zone as a food source! it would appear to have some difficulty in the phenols within oaks however, but in a horsechestnut its a savage which can consume it in a frightening space of time.

 

G. lipsiense (= G. applanatum) is not wholly saprobic, it is a slow parasite, which together with the tree under attack wants "to get old" to be able to yearly form new reproductive layers for as long as possible, i.e. it has no benefit from an early fall of the tree. This way, the diameter of fruitbodies can reach up to 60-80 centimetres. To prevent the fruitbody from becoming too heavy, old specimen "consume" and reuse the inside sterile tissue for building of new fertile structures so that they become partially hollow.

G. australe (= G. adspersum) is not only extremely detrimental to horse chestnut, but also to Acer, Tilia and Quercus rubra.

I take it from your smiley Hama, that "Fungus" is a highly respected mycologist?

lets hope it's not going end up like mr tree!

 

if Mr fungus leaves because of "us" I would follow, no seriously, ive nothing to add here in this forum without raising my game, and I cant raise my game without better players around me.

 

I do hope we ALL appreciate Fugus'es input here, we all have a lot to learn here.:thumbup1:
