Hamadryads fungus diary

[Bundle 2]

I'd been thinking about the exudate, but I think it's likely that some species not noted for producing exudate produce it occupationally, in response to certain conditions.

Your brackets might be producing exudate now, in response to the sap rising in the tree, either to actively modify the moisture content of the wood, or passively by being tapped into the tree's vessels and the tree is pumping it out. That passive 'idea' is speculation and might not be possible for all I know!

 

Perhaps the function of the exudate is the physical result of the fruit body as it is "modified" with spore production, well release probably, in mind. I accept that fungi sporrulate using differing mechanisms so should need to ponder this further to be fair. I find the point Hama makes here more readily appealing however and agree with the logic he extends as to the reasons for this characteristic ....

Thinking out loud, I find it perfectly feasable that friut bodies should be "influenced" to some degree by the saturation of the cells ( aka turgidity ) This would suggest that the positive hydraulic pressures affected by a trees vascular system could be used to the advantage of the fungi's friut body production. ( I have not stopped to consider other ways in which this could manifest itself but such are the restrictions of "thinking out loud" ) Why then would we not see a variation in the exudates produced from species to species and this is likely effected by fungal species aswell as tree species, and recent climactic events....eg; rainfall. topography soils etc ) Changes in the trees vascular status give rise to the droplets and sap status may well be influencial. So then, it could give rise to the type of exudate you are seeing Hama.

hi good thread and never thought about spore release through exudate...i thought this pic shows a good example of it.

Posative pressure is of no consequence to a well established and fruiting Mycelial mass that is not only well plumbed into the trees system but causing a great deal of dysfunction within its transport network, effectivley "plugging" the vessels of a tree. IMO

 

Copious amounts of liquid may benifit the fungus in the development stage, like a fetus forming in a liquified environment, the liquid is no longer desired as spore release begins. This may also help determination of spore release by tempreture/humidty the drying or moistening of a fruit body giving rise to perfect conditions for the released spores to find a suitable place and conditions to form a mycelium. This way spores are released ONLY when they have the optomum chance of survival.

 

I thin this is why, the wound loving parasite laetiporus sporalates ( also Hispidus) in warmer weather, through the course of evolution, these fungi have been evolving along with thier favourite hosts, the Oak, and the Ash respectivley. summer sporalation for these two fungi means that their will be a very high chance of spores finding a newly formed wound as in the branch drop synominous with high temps and humidity. The Laetiporus prefers to get in such a wound (socket failure at limb junction as it likes to be in the zylem rays, hence the fruit body formations, multy tiered, exiting via rays.

 

IMO and all speculation of course.

Thats a corking shot steve, love it, realy good example, and highest up trunk i have seen of inonotus dryadeus, never seen it in combo with a ganoderma iether, here with Applanatum in your Holm oak scenario.

 

GOOD post:thumbup1:

Warning: The following is speculation / cod science and contains a dodgy analogy.

 

We had a pin-hole puncture in a central heating pipe that didn't leak when the system was cold, but dripped when it was hot because of the pressure increase. Some brackets might work in a similar way, without it necessarily benefiting the fungi. That might explain why it's an occasional event for some species of fungi that aren't noted for dripping, rather than being a regular occurrence for them.

 

 

As for spore release, whilst that might be a factor in 'regular drippers' like Inonotus, I imagine there must be more to it than dripping spores onto the wood that the parent fungi is inhabiting - I can't see how it would benefit the species to have a system that competed with itself?

aye up lad! good shot!

 

sometimes i think you like throwing spanners, bet your old enough to know a record called monkey spanner too! lmao

Very apt

"Posative pressure is of no consequence to a well established and fruiting Mycelial mass that is not only well plumbed into the trees system but causing a great deal of dysfunction within its transport network, effectivley "plugging" the vessels of a tree. IMO..."

 

Im not sure that positive pressure would be of "no consequence" as you put it. In fact, it is more likely to be the only mechanism at work if the vascular function is seriously disrupted? This cos transpiration is not a process that can be relied upon resulting from said "disruption" Thats what "dysfunctional " means unless Im missing something here. Dont get me wrong, I too am speculating. Im put in mind of saprophytic species all of a sudden.....

BTW, arent the most vessels actually present in coniferous trees ( so softwoods ) This where we find the "pits". The anatomy of softwood is significantly different to broadleaved hardwoods...sorry, stating the obvious but the detail is certainly of significance if speculating ( which is of interest esp on forums ) ....

Never seen a gano sweat. Nothing much surprises me about fungi! I should phrase that somehow differently. Nothing but surprises are the norm with fungi...yeah, that's better!!

Great image of the robustus btw...quality!
