Thank you Leuba. Interesting info to research.
The brown fans in your spotting are old and dry and are perhaps a pleurotoid fungus or a species of Crepidotus. Someone more knowledgeable might be able to help. You've, however, got another interesting orange fungus, like fruit peel, on the log (pic 2) which could be a Tremella species. If this is so, then you might have a third species (unseen in your photos) residing in your log - that would be Stereum. Tremella are said to feed on Stereum.
