wasnt the hypholoma

 

What do you recon it was that caused it to fail at the base? No fbs of HF and in a sheltered locaation so couldnt have been wind. Was still alive too.

Hypholoma fasciculare is a saprobe and not a parasite so was only a secondary coliniser, it is also antagonistic to Armillaria, though i am still to test thaT THEORY BECAUS EiVE SEEN THE TWO ON ONE STUMP

 

caps in error

Here's the cap shots

 

Judged by the shot of the cap from above, I would also say it's Armillaria mellea s.l. .

It's antagonistic to the mycelium, i.e. not the rhizomorphs, of Armillaria, because H. fasciculare decomposes dead wood with polyaromatic hydrocarbons, the enzymes of the hyphae of Armillaria can't compete with.

thats as good an explanation as i could have asked for:thumbup1:

 

this was touched upon recently but no conclusions so interesting that you had answers where these two did not.

Tony,

The same even more goes for Bjerkandera adusta, which mycelium produces up to three times as much PHC as the mycelium of Hypholoma fasciculare, and much less for Mycena galericulata and some other wood decomposing Mycena's, of which the mycelia only produce half as much PHC as the mycelium of H. fasciculare does.

Thats interesting, and i think that this info will stick this time:thumbup1:

 

Can i also ask what enzymes these fungi use in order to produce these PHC's what constituent are they breaking down other than cellulose?

Ligniolitic enzymes breaking down lignin first before decomposing cellulose with organohalogens such as PHC.

A wide variety of the fungoidial stuff out there currently
