Keizer's Fungi Q & A.

[Fungus]

on spruce i think, maybe pine, already recorded P. flammans on this last year, and struggling with this one, ruled out P. clavicola for that would be on deciduous

 

Tony,

What is P. clavicola ? If both photo's show the same species, I would think this might be a partially resupinate Heterobasidion annosum.

my bad phelinus cavicola! so you think it might just be H. bassidion in a resipinate form, never even considered it!

Ahh, you mean Phellinus cavicola, the lover of cavities .

Arrh thats what that means! and probably explains its rarity, not seen very often

What you make of these then Gerrit? bolete under beech, small mushrooms under castanea sativa and amoung wild raspberries

bolete under beech, small mushrooms under castanea sativa and amoung wild raspberries

 

1. Boletus radicans.

2. Collybia dryophila.

3/4. To young to identify, could turn out to be a Psathyrella species.

thanks, here to ask again!

 

So, Mycorrhiza and panic, whats going on here?

 

This beech was cleary partialy live on failure, we can see the root that delaminated and tore a strip of the stem. The fungi (mycos?) are boletes of some form, maybe chrysenteron? it is fruiting off the wood, well rotted, fruiting only within the bowl of the shear root ball, and LOTS of it, photos show no attachment to fine roots, to the point of having leaves under their attachments? last two just some nice calocera cornea that where going bananas on this failure.

1. Yes, Xerocomus (= Boletus) chrysenteron s.l., an ectomycorrhizal generalist of deciduous and coniferous trees, associated with the middle and/or final phase of the life cycles of trees, although seemingly growing on dead wood, panic fruiting from the remaining living fine roots deeper in the soil, while uptaking a bit of easy accessible cellulose on the side, which also is known from other generalistic Xerocomus species, such as Xerocomus badius.

2. Prolific fruiting as a pioneer on a yet very rich substrate.

[Arctostaphylos uva-ursi]

Can you help me with the identification of these please (see attached photos)? Are they both P.schweinitzii?

What is the significance of finding these on mature (40m tall) Sitka spruce? I am concerned because the trees these fruiting bodies were found on/by are growing close together with fused root systems? Is it therefore possible that the roots may have a greater extent of decay than might be detectable in the butt?

1. Yes, they both are.

2. P. schweinitzii is an annual necrotrophic parasitic bracket fungus, which causes an intensive and often fast spreading dry brown rot in the major roots, butts/buttresses and/or the trunk base of coniferous tree species.

The tree becomes vulnerable for windthrow and the falling of the tree sometimes takes place before FB's have been produced, because the mycelium can switch to brown rotting the remaining wood as a saprotrophic once the tree is dead.

Because of the fruiting with two well-developed annual FB's from dead wood, in this case, I would expect that the mycelium has already "jumped" to the roots of close by standing trees with root-root contact with the affected trees.
