An interesting find on the next door plot

Here’s a tiny cluster of fungi I noticed while we were talking to our neighbour on the allotments. I’m absolutely not a specialist in this field, but I had a look through the books and I think this may be Helvella leucomelaena – the Sooty Cup or White Footed Pixie Cup.  If it is, it’s not where it should be and it’s quite rare.  However, we use so much wood-chip on the allotment it could be one of those species that’s benefited from human activity. Any experts out there?
