An interesting fungus we found at Heartwood is Clitocybe houghtonii (see photo by Claudi Soler).  From above it looks like one of those fairly nondescript off-white Clitocybes, but it has pale pink gills and is supposed to smell of tomatoes – some of us could smell it, some couldn’t.  Apparently, it is nationally uncommon but turns up quite often in Herts.
