Found growing on ground under conifers.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
H leucomelaena is quite rare and is blackish brown turning to white near the stem. I'm not sure that this is one of those. My guess would be the empty puffball from a Handkea utriformis which, as it happens, was the ID agreed for the first cup-shaped mushroon that I found - which I mistook for H leucamelaena! See http://www.ispot.org.uk/node/239055
This could be H leucomelaena, which is not one I have seen, but it could also be one of the Peziza family and without microscopic examination I don't think we will ever know. I am sure it is not H utriformis though.
I'm pretty sure they are not the remains of a puffball.. I'm fairly familiar with what they look like.. ie these were not papery in texture but more akin to scarlet elf cup which I've also seen this spring.
I am using Roger Phillips Mushroom for identification.. so am limited to finding the closest match in there.
OK. I wish I'd seen a Scarlet Elf Cup but so far they have eluded me.
I had never seen one before last year but have made a concerted effort this year and found it twice.
