Keizer's Fungi Q & A.

[Fungus]

obviously Armillaria, rapid decline then death of pinus nigra, this mycelium is not characteristicly fanned like that of the mellea, but consisting of much longer less rapidly fanning out mycelial patterns. could this be ostoyea?

 

Could be, could also be Heterobasidion annosum. To be 100 % sure, wait for the FB's to show up.

ground it out!

 

I was unaware that Heterobassidion made fan like structures of mycelium under the bark, from top to toe in this way, thank you.

It have been some 'low activity' weeks on Arbtalk for me, meaning lots of pictures (and the subsequent questions)

 

1&2 bad picture of Pholliota spp. on beech on a old wound 6m high. Does not look like aurivella to me, but too high to be squarrosa

3&4 white slime mould? and G. applanatum

5 sterile lump of Fomes fomentarius??

6,7&8 I'm confused about this one: looked like Grifola frondosa at first, but on beech, then tought Meripilus, but does not look right either

9&10 Meripilus on Quercus rubra?

11&12 is this fomes fomentarius going 'bananas' because of the abundance of wood to decay? It's popping out everywhere on this recently monolithed tree

13&14 what does the body language of this Acer saccharinum tell you? Looks like it's slowly sinking over it's root base --> white rot? Or is this just an old graft?

15&16 Pholliota aurivella?

17,18&19 no idea, in the root area of old beeches

20&21 lousy phone pictures of a fungus on an old Pinus nigra stump; Armillaria??

Tom,

1&2 : Because of the height of and the fruiting from an old wound on beech : P. aurivella.

3&4 : Yes, Fuligo septica var. candida.

5 : .

6,7&8 : My bet would be on G. frondosa. Did you do the scratch test on the pores and did the pores turn black after a while/a day ? If so : M. giganteus, if not : G. frondosa.

9&10 : No, Grifola frondosa.

11&12 : Yes, being a necrotrophic parasitic, it's triggered to fruit by the monolithing of the beech.

13&14 : I think it's just an old graft.

15&16 : .

17,18&19 : Smell of bitter almonds or marzipan ? If so, Hebeloma radicosum.

20&21 : If the species is the same on both photo's, no Armillaria (white spores), but a species with rusty brown spores, could be Galerina marginata.

definately grif on the beech, stonking find fella:thumbup1:

Thanks! This was only the second time I saw Grifola 'in the flesh' and the only thing I remember is it actually smelled like rotten flesh (or maybe some dead rabbit was burried in the leaf litter )

Thank you Gerrit,

 

I didn't smell, so no idea.

 

The biggest FB's in the last pictures were almost 20 cm in diameter. Isn't that too big to be Galerina marginata? By the way: where do you see the brown spores? On the ring?

Tom,

1.Yes, it is, so how about Gymnopilus sapineus then ?

2. .

Hi gerrit, had an interesting chat with a client today, about fungi under a willow, no fruit present at time, no trees even within a stones throw, and i am a good chuck! he described paxilus involutus, its a healthy young almost mature willow with no damages to roots.

 

Willow is endomycorrhizae isnt it?

[sloth]

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...
