Keizer's Fungi Q & A.

[Fungus]

on an Oak stump in Windsor a number of years ago and believes them to be a Cantharellus species ?

 

David,

It certainly is a Cantharellus, probably C. tubaeformis. Being an ectomycorrhizal symbiont, fruiting on an oak stump is only possible if the mycelium is still in contact with intact and living (secundary) roots, like f.i. happened when the wood of Q. rubra still was used by the Dutch bakers for their ovens and the coppices regenerated roots after they had been cut for this purpose, which set backwards the "order" of succession to an earlier stage.

Thanks Gerrit, that confirms what my colleague had suspected.

howdee Gerrit,

 

what would this Fuligo be feeding off ?

 

This layer of stone is perhaps 4 or 5 cms deep.

 

dead woody material below this ?

 

The roadside Oak bollard behind it is 70/80cms away.

The plasmodia of myxomycetes have an "open belly" down under, with which the substrate is "grazed" for organic materials (bacteria, algae, spores and hyphae of fungi, rotting plant debris, etc.). Indigestible parts and dead parts of the myxomycete are left behind in the silvery "snail sliding trails", which follow the tracks of the plasmodium while moving about.

Thanks once again Gerrit

Very wet morning here, so openend up the unknown files

there's lots of them

 

First one up to the oche is..........

 

Laccaria perhaps ?

Laccaria perhaps ?

 

David,

Laccaria species are ectomycorrhizal, this one seems to grow at the base of a trunk of an oak (?), so this is Collybia fusipes with the characteristic pointed base of the stipe and the dark red to blackish spots on the cap.

Should of gone with my gut instinct

 

Went & flicked through a few books, got side tracked.

 

Colour threw me.

Monkey D, go and stand in the corner with your hands on your head!

gerrit, what do you think these black exudates are with fistulina exit wounds? vinegar acids maybe due to enzymatic actions?

 

 

and what causes this mutation in fistulina hepatica?
