Oak Myco associations

[David Humphries]

As part of a London Natural History Society Survey.

We're looking at & recording the range of different genus of fungi associated with a couple of trees over the next 6 months.

 

The intention is to watch the succession of Mycorrhizal & Saprophytic species every few weeks.

 

The Hosts are pretty interesting.

 

Couple of Quercus that are the surviving remnants of an area once heavily excavated for sand & are now enclosed in a younger canopy.

Some of the mycorrhizal species that we came across today........

 

Amanita fulva

Amanita rubescens

Russula (tbc) risigallina

Russula (tbc) intermedia

Laccaria amethystina

Laccaria proxima

 

I will update as the list will expand over the comming weeks & months.

brilliant pics, Dave

I remember you used that first pic in another thread. Is the pic dated?

[Tony Croft aka hamadryad]

thats interesting, amythystina under oak?

Nice project . In assessing and monitoring the tree species specific macrofungi of Tree Species Specific Ecosystems of indigenous trees, over the last 10 years I've done this several times in The Netherlands, Belgium, Luxemburg and Germany over 3-5 years periods and in Sweden, Danmark, the Czech republic, Switzerland and Austria on a 1-2 years base in forests dominated by Quercus robur, Fagus, Carpinus and Betula or Picea, Abies and Pinus.

About what age of oaks are we talking here and do you want a list of species you can expect to find or need looking for ?

And what species is Russula intermedia ? I can't find it in any of my books and literature on Russula.

amythystina under oak?

 

Yes, as a pioneer symbiont, mostly associated with the finer roots of (seedlings of) beech, but also associated with oak, especially when oaks have been or are part of (the edges of or open places in) beech woods.

I should coco

 

Carpets of them today, in what is most definitely an Oak woodland.

Few very young beeches scattered here and there.

 

This troup is directly associated with the surrounding Oaks.

 

 

Have read of the association, but not something I had really seen before.

usually not tuned in to it, leaving it for the more obvious Beech woodland.

How often were you visiting the study sites Gerrit ?

 

 

R. intermedia is in Roger Phillips Book.

I'm only pre-proscribing based on cap colour, gills & habitat.

A colleague at an adjacent site will verify for me with reagents & a scope.

 

The Oaks in question are possibly 3-350 years old.

They're certainly old trees in the original shot above from the turn of the last century.

Pleased they are to your liking

Used then for the start of this thread Graham.

The first shot is from some point in the 1860's apparently.
