Are there any Paleobotanists that can identify the organic composition on the outer husk of the agate?

I do not have an answer for you other than this, organic matter can decompose leaving an area that fills in with silica which forms agate under certain conditions, much the same what agatized petrified wood is formed.

Hello Weasel, what you say is reasonable since the "organic composition on the husk of the agate" has turned into  what looks like agate. What I am hoping to find out is the name of the original " fungus, " thus my call for any Paleobotanist who could perhaps identify the organic matter.

Cheers, arbayowling
