Don’t have any fresh material….

I did note the context color as being pale yellow. However, even Hesler’s description said “concolorous to light buff or warm buff”. Quite a range and “buff” isn’t exactly a definitive color for me. Thin flesh doesn’t help the situation.
These were all fully opened mature fbs so if there was a yellow veil, it wasn’t obvious, although some scattered yellowish fibrils can be seen.

too bad…

you don’t have views of the context or PV, both apparently distinctive.

Do you still have a fresh fb?

Thanks Richard..
