At our microscope talk, Emily and Di brought along an orange-coloured Elf cup, which apart from growing a small branch looked for all the world like Aleuria aurantia, the orange peel fungus. (Emily/Di do you have a photo of it??). However looking at the spores etc it does show all the characteristics of Sarcocypha austriaca, the Scarlet Elf Cup: i.e truncated spores, measuring ~31x13 μm. nodule growth on some spores and curly rather than straight hairs on the outer surface. These are all shown below.
There doesn't seem to be much information about orange-coloured Sarcoscypha on the internet, have you seen any before Philip?
