Know your fungi - Nomenclature etc

[Tony Croft aka hamadryad]

Worth noting that as of the 18th International Botanical Congress in Melbourne in 2011

 

The concepts of ananomorph (asexual reproductive stage) & telemorph (sexual reproductive stage) will now been eliminated from the international code of nomenclature. In part to ensure that one fungi is given one name.

 

 

Thats nice

 

 

Comes into effect from Jan 2013

good info David, I think thats a shame really, as they can be very different in form, like "confistulina" for example.

they keep on tinkering away, just to keep us on our toes

they do, but im so used to it now, changing names etc

 

I just go with it, as long as I keep up the seminars I get to find out what the new names are:lol:

 

had to laugh when at Kew BMS meet the guys says "coprinopsis picacea" im like whats this? lol till he said oh yes your probably all still thinking calling coprinus!

 

No wonder noone wants to take up mycology!

 

worse than rocket science, at least a rockets name never changes!

So one problem solved, another created. What to do with species of which only an anamorph is known without a teleomorph being documented ?

we'll just have to double our efforts to find them then

 

 

 

seriously though, I see your point. I'm not sure how the continual change in the mandotory rules & recomendations (although designed to unify the classification of fungi) actualy help, in terms of all the 'current' identification books & resources out there.

Do you have any pics of confistulina? I can't seem to Google any, unless they look the same as F hepatica.

Please could someone also explain the difference, and why it may fruit one way rather than the other.

Many inquisitive thanks...

one is the sexual fruit body see second image first image confistulina (thanks Gerrit) the asexual fruiting body or anamorph

 

 

[sloth]

Cheers. Very familiar with the sexual fb, never to my knowledge come across the asexual anamorph. It looks almost like a malformed normal fb. Do any other principle wood decay fungi have an anamorph form? What are the benefits/why would the fungi do this, does it produce spores even? Thanks again...

1. Do any other principle wood decay fungi have an anamorph form?

2. What are the benefits/why would the fungi do this, does it produce spores even?

 

Sloth,

1. Yes : annual bracket fungi such as Laetiporus sulphureus --> Ceriomyces aurantius; Abortiporus biennis --> Ceriomyces terrestris; some Oligoporus species such as O. ptychogaster --> Ptychogaster alb(id)us (= P. fuliginoides) and the very rare and only recently discovered Ptychogaster anamorph of Oligoporus guttulatus.

2. They produce chlamydospores, which is part of an "ancient" dual reproduction strategy.
