I recently got some large logs from a neighbour to create a “fernery” but this fungus has appeared on the ground immediately next to the logs. The logs originally had the bark on them but the harsh frosts detached the bark. the fungus does not have any stalks, the cups appear to emerge directly from the soil. I would like to know (1) what this fungus is and (2) whether it is a “goody” or a “baddie” – will it put my trees at risk? The new fernery is in the centre of three Silver Birch trees. Many thanks Hazel Luskin Glennon
