Re : indet. Rutstroemiaceae sp. on unk. fallen leaves
This is difficult. One should check White's monograph of Rutstroemia.
Splendid photos! Did you measure the spores? Are some photos greyscale? The excipulum should be a prismatica-porrecta.
ITS Blast gives with 99% (4 nt & 1 gap) an Uncultured isolate (dfmo0688_132) from USA, North Carolina, isolated from mixed hardwood litter layer. - More distantly 96% R. punicae, 95.5% R. tiliacea, 95.3% R. echinophila, 94.5-95.5% R. firma
Zotto
