I’ll return in 2-3 days and if no other mushroom observer fanatic has removed it meanwhile, will add details to this observation

Not all Albatrellus terrestrial.

Sometimes it can be growing from rotted logs, as in this obs.:

Albatrellus avellaneus Pauzar (9710)

A. avellaneus is a species which is rare locally, and associated with the ROD (Record of Decision) of the Northern Spotted Owl.

Were it not so rare, I would have gladly sampled it. It has a very pleasing, light fungal aroma I find appetizing.

I know many Albatrellus are associated with bone-hard material. But not always. Similarly, not all Albatrellus are terrestrial: some grow from well-rotted wood.

There are other options too.

Polyporus leptocephalus formerly known as varius is very common on almost every deciduous wood. Similar is Polyporus melanopus with more brownish stipe, P. nummularius is taxonomic unnecessary it simply is a dearth form of nominal species especially on thin dry sticks. To be sure you needed a scope. One has clamp connections the other not. Polyporus badius also has a black stipe. Furthermore this specimen is young. Did you take it or could you return in a few days?

Well, I am certainly not sure either :)

Leptocephalus is supposed to have lateral stipe, no hard crust on cap, ocre-yellow color, thin to medium thick cap.

The var. Leptocephalus nummularius is supposed to have a central stipe, black at its base

I admit I’m not familiar with Polyporus leptocephalus

so checked other obs. on MO. Looks like there’s quite a variety of species, which do not look at all like each other to my eye.

So where is a good description of P. leptocephalus? Does it have a black stipe with no pores on the bottom black portion? Does it have a white stipe with larger pores towards the base? Is it a pseudostipe with larger pores towards the base? Is it more common in Europe and Asia than the US? Oh my aching head!

Growing on dead hardwood

Unlikely to be albatrellus, as this was growing on dead hardwood (probably beech)

Rather cheese

Hard like a cheese

Hard like bone? Soft as cheddar cheese?
