Keizer's Fungi Q & A.

[Tony Croft aka hamadryad]

I'm gonna stick my neck out (and wait for the chop!) here by saying P involutus still has the ability to act saprotrophic fungi. Can't remember from the list Gerrit kindly posted whether Salix is endo or ecto or both though...

 

yes Sloth, but i am hinting at it acting as a ecto on trees that are known endo trees!

This fungi is posted on treebuzz. we do not know what it is, I have looked in all my books and can not find it...however I know you guys are experts can you help? It is on the base of an Oak

[Fungus]

about fungi under a willow, no fruit present at time, no trees even within a stones throw ... he described Paxillus involutus, its a healthy young almost mature willow with no damages to roots. Willow is endomycorrhizae isnt it?

 

Tony,

No, only as seedlings, Salix is associated both with endo- and pioneer ectomycorrhizal symbionts, full grown willows are associated with ectomycorrhizal macrofungi, some of which are exclusive for Salix and part of the tree species specific ecosystem such as Russula subrubens, Tricholoma cingulatum and Cortinarius urbicus.

Hello Gerrit,

 

any thoughts/experience on whether species can hybridize?

 

Is it even possible?

 

regards

Yes, many species of fungal plant pathogens with low genetic diversity, such as patato and chestnut blight or Dutch elm disease, can. See the article in the nature journal.

Thanks for the link Gerrit.

 

At a recent Forest Health seminar, one of the speakers described one of the species of Dothistroma posibly having the gentic ability to hybridize (I think)

 

I was more interested in whether there is any evidence of macro fungi hybridizing?

[Fungus]

1. species of Dothistroma

2. ... whether there is any evidence of macro fungi hybridizing?

 

1. The genus Dothistroma or Mycosphaerella also is a (ascomycete) blight colonising all kinds of plant or tree leaves and needles.

2. No, not to my knowledge.

Specifically refering to a major problem with red banded needle blight here in the Uk (and elsewhere) on many, many (60+ sp) of Pinus.

 

Doesn't look good
