Fungal guttation

[David Humphries]

A common phenomenom that is often witnessed on annual polypores.

 

Not entirely understood from a scientific perspective but is usually noted to be during the rapid growth process of the fruit body development.

 

Occasionally I've noted it on the beefsteak fungus (Fistulina hepatica) including its anamorph

 

 

The greasy bracket (Aurantiporus fissilis) often presents with exuding droplets

 

 

The chicken of the woods (Laetiporus sulphureus) can be seen glistening with underside jewels of liquid particularly whilst using a flash.

 

 

A regular site on the shaggy bracket (Inonotus hispidus)

 

 

Can occasionally be witnessed on perennial brackets like the horseshoe bracket (Fomes fomentarius)

 

 

but the undisputed king of fungal guttation is the oak bracket (Psuedoinonotus dryadeus)

Seen this plenty of times, least I can put a name to it now and sound like I know what i'm talking about

 

Thanks David

Very nice pics. I wonder what is contained in the droplets of various species, same compounds or different? Like everything in nature I expect there must be a reason for it. I've heard suggestions of it being a means to adjust the moisture content of the colonised wood, but I'm not convinced by that...

I think I've read or heard David Lonsdale saying he also didn't believe that suggestion, likening it to an old wives tale.

 

I think it's more to do with regulating moisture content in the rapid development of the FB.

Fascinating , arbtalk is a splendid learning resource

I saw this a couple of weeks back, I thought it looked like guttation.

It's possible I guess, though I've personally not noticed Kretzschmaria guttating before.

I hadn't either. It could have been dew like condensation but didn't look like it. I'll have a look up and see if it's still at it.

Does it count if Bob the dog cocks a leg on a low down fungi?
