I found some 5 polypores attached to the bark of living Quercus ilex (Holm oak) trees in a park, somewhat damaged by Xmas lights decorations. The core is composed of 2 (or 3) layers. The hymenophore is soft. I managed to see few spores too, apparently thick walled. The context stains deep reddish-brown with 4% KOH. Could you help in the ID please?. Young Inonotus (Inocutis) dryophilus ?

Hello, Steve!
If the context is truly dimitic (real skeletal hyphae without septations), then this would be a Phellinus.But sometimes it can be quite difficult to distinguish Phellinuzs s.l. from Inonotus s.l., especially in young fruitbodies.
Just guessing - how they grow, an which substrate, and how they look: This might be Phellinus robustus (= Fomitoporia rubusta).
If they grow older, they should become really hard. And of course dimitic and without any setae.

Hello, Steve!
In Inontus You might find some "skeletoid" Hyphae. Those would look similar to true skeletal Hyphae, the septations may be difficult to find. So it is a clue, but it is also not easy to observe.
One of the reasons, why i don't like working Hymenochaetales (especially phellinus): They are really ennoying under the microskope! Hard, dense - difficult to preperate and difficult to interprete.
Inonotus dryophilus sounds good, though.They should be more or less soft when young and crumbly when decaying.

Yes, that's what the case and also dark reddish-brown when overmature and decaying out. I think I found a similar specimen on Celtis australis again above grown and on the bark of a living tree on mainland Malta. Crumbling brown debris was at the foot of the trunk and fall down on the ground

Yes, I haven't grasped very well the concept of monomitic / dimitic / trimitic, generative hyphae, skeletal hypha, etc when examining under the microscope. They just look like a brush of unspecialised mycelia entangled into each other. I had a look again this morning and I an interesting parasite!

Look what I found in the mycelia of this Inocutis dryophilus. A mycoparasite
