very few 3d coiled conidial general exist in north america, the most similar would be troposporium who do slimey sporodochia (probably a bit similar to leucogloea) on corylus and is unseptated

a placed a special camera for microscope on my dissecting microscope , but i needed to do extensive cropping to the picture to get that result, but the rest was just out of focus wood anyway.

Great observation Jonathan
