Note strong baseline joining the letters... This is ideologically Viridian, implying growth from the base-- the grassroots, like they used to say-- which appears to be exactly what the small fungoid critturs did to form the letters.

Every sheet is invisibly lined; lines are incorporated into the sheet with different intervals for different font sizes, giving a fair starting lineup from which activated fungi will nudge their neighbors into action.

The letters suggest rusting ironwork as well as lichenous twigs. This is good.
