Probably giant funnel (Leucopaxilus giganteus) which has a white cap, decurrent gills and no ring. The stipe appears too short for Trooping Funnel.
Russula silvestris is found under beech trees and forms mycorrhizal attachments to them. Since the flesh is white it is probably not the Beech Sickener.
Shaggy Scalycap (Pholiota squarrosa) is easier to identify since it grows at the base of trees and is shaggy all over.
Jelly Ear fungus shown above (Auricularia auricula-judae) is very common on Elder and other deciduous tree. Although it is common and quite palatable in stir fries, foraging for fungi is not recommended. This one was growing in Heaton Park on a fallen log sculpture.
