I think the mushrooms in the lower photo are Omphalotus olearius, known as the False Chanterelle. The gills and the colour look quite a bit like chanterelles but they are growing in a batch, growing on wood, and they are light and hollow, unlike chanterelles, which are chunky. I wonder if the group in the top photo are the same kind of mushrooms only much younger? I’m thinking this could be now that I’m reviewing my photos, but I didn’t make the association at the time, in part because I found these clusters hours apart in different tracts of forest.
