The downed oak habitat

In February 2022 an ice storm uprooted a huge oak west of the barns. It fell into a stand of younger trees growing in what eighty years before had been a cattle pasture. The photo below shows it in September 2023. The second photo of bark, moss, polypore and geranium is a microcosm of the whole little system. The third photo shows off the fungus most prevalent and most conspicuous in this little system as of September 2023. This is Sterum complicatum, along with a companion also heavily represented, Trichaptum biforme. Trametes betulina may be third-easiest to spot; it seems to be everywhere.
That autumn, while cleaning up some of the debris, I saw many fungi on the trunk and branches that caught my beginner's eye. I made close to seventy observations on i Nat in October-November and added three in September 2023. I got wonderful help from members of the i Nat community, notably Sarah Duhon, Misha Zitser and John Plischke and from NY Myco Society virtual ID sessions.
Among the seventy observations on this tiny ecosystem, twenty species of fungus and one of lichen have at least one Research Grade observation. A few species have several. Another seven observations of fungi are posted at the Genus level. These include some crust fungi, which that I've noticed are very hard to identify below Genus level from macro photos alone. One lichen is posted at species level that is not confirmed.
The twenty-nine observations of fungi (mostly) or lichen that are at Genus level or lower are listed below. A fungus with more than one RG observation is listed only once.
This was a good learning lab for me as a novice identifier privileged to interact with others who know much more. It's also the start of a chance to follow future outgrowths.

Descripción

Stereum complicatum and Trichaptum biforme on the downed oak. In September 2023, nineteen months after the tree went down, the most prevalent fungi I note are S. complicatum, T. biforme and T betulina. S complicatum occupies the most square feet and blazes with color on this rainy day.
