Growing on woodchips under Veronica cultivars. Adjacent to Betula pendula; reaction to ammonia reddish orange, not green; cap dry, not slimy; colours, a dull reddish-brown; spore print pale yellowish, not greenish; spores ovoid.
I think this could be a slime mold, however on the back side of what I think is an acacia, there was white hypha, so it might not be (or course the hypha could be another fungi)
Got frustrated by my camera as it isn't a true macro lens, and my proper one broke.... so this is as close up as I could get.
The out of focus shot, is focused further down on the red filaments that hold up the 'caps'
