Hi all

Er indoors has spotted what looks like strange fungal outbreak in one of our
borders!
There is nothing planted in the border, and the growth looks just like
numerous orange petals laid on the soil surface.
Each "petal" is between 6mm and 10mm across.
The location is East Yorks in a sheltered(ish) spot.
The only source I can think of is unrotted kitchen compost being buried
under this border 18 months - 2 years ago.
Any suggestions on what this is?
Tried searching the pics on UK Fungus site with no luck.

TIA

Phil
