Expert ID Please
Ladies and Gentlemen I appreciate you taking a look at this fern. I have been unable to positively identify it. I wish I had better photos, but I didn't realize what I was looking at, at the time. I looks to me like an Asplenium. Native to 1,200M (4,000 ft) cloud forest on the Big Island of Hawaii. It looks like a Diellial leucostegioides. That's unlikely, but not impossible, as that species is considered extinct. Here is a link to the best information I could find on the genus.
I have also reviewed the new book "Hawai'i's Ferns and Fern Allies" by Palmer.
