Melanospora cf. lagenaria on old, rotting, fallen and still attached FBs of conk (possibly Fomes sp.)near Purchase Road, Appalachian Highlands Science Learning Center, Great Smoky Mountains National Park, Haywood County, North Carolina, USA
https://www.inaturalist.org/observations/305939943
Collected during the 2025 Richard P. Korf Memorial North American Ascomycete Foray (aka "The Korf Foray), held at the Appalachian Highlands Science Learning Center in Purchase Knob, North Carolina.

Of what I believe are two distinct ophiostomatoid fungi shown, the larger of them is the target organism, and it is spores from this fungus which are shown in the micrographs and in the measurements below.
Spores:
(10.7) 11.6 - 13.2 (13.7) × (6.4) 7 - 8 (8.4) µm
Q = (1.5) 1.54 - 1.7 (1.9) ; N = 20
Me = 12.3 × 7.5 µm ; Qe = 1.6
Different references give different spore size ranges for M. lagenaria, and if anything our spores seem small by comparison. Our collection would appear to constitute a range extension for M. lagenaria, if it can indeed be said to be that sp.. Is there another possibility?
Any and all help is greatly appreciated. Additional micrographs available upon request.

Hi Danny
My own european collection on Fomitopsis (Piptoporus) betulina seems to match yours well. I think you should study the hairs.
