Fungi Identity- a tester!

[Tony Croft aka hamadryad]

I wonder if we could do with a glossary of terms thread for those of us without as much knowledge of Posh Words, maybe stickied so its easy to find and refer to, and not to be de-railed! Just a thought:001_smile:

 

That is a good idea! after all who wants to explain EVERYword used everytime! would be a nightmare and somewhat patronising!

"Accounts from Europe report beech bark disease, caused by the fungus Nectria galligena Bres., has been killing beech trees (Fagus spp.) since before 1849. Until 1914, the beech scale insect Cryptococcus fagisuga (Lind.) was thought to be the causal agent of the damage. It was then learned that the Nectria fungus actually infected the trees through the feeding wounds of the insect and resulted in the damage. In North America beech bark disease has been attributed to N.coccinea (Pres.:Fr.)Fr. var. faginata Lohman, Watson & Ayers, although the native species of N. galligena (Bres.) is also known to be a causal agent of beech bark disease.

This is the conidial form (asexual) of the "Quaternaria spp " which is known to host by beech (Strouts & Winter pg 102 )

I think if you'd told us that Bulgaria inquinans was hosted on this beech, we might have made the ID..but that would spoil the fun!.Here's an image from good ol Rogers mushrooms which I believe shows the conidial stage of Bulgaria inquinans...as was said, macroscopically similar? I hope this helps.....

Conidium - Wikipedia

 

Conidia, sometimes termed conidiospores,[citation needed] are asexual,[1] non-motile spores of a fungus; they are also called mitospores due to the way they are generated through the cellular process of mitosis. They are haploid cells genetically identical to the haploid parent, can develop into a new organism if conditions are favorable, and serve in biological dispersal.

 

Asexual reproduction in Ascomycetes (the Phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive of a specific species and can therefore be used in identification of the species.

 

The terms "microconidia" and "macroconidia" are sometimes used.[2]

Yes it would have spoiled the fun!

 

I had been watching the tree for some time to learn this, and didnt find a satisfactory answer in my books, non conclusive. I am glad to see there is some infor out there that confirms it.

 

thanks guys, hope this was interesting?
