DailyFlash: Mushrooms

Once upon time ago, an eon far gone, pre-Mesozoic and further still, the vertebrates unlinked and the tetrapods unlimbed; pre the branching colours of coral undersea, grew fungi: in an alienscape, all shapes at sizes small as thought or large as time, hooded umbrellas spreading wide canopies in burning yellow light as saturated as the skies back then. Spores barely spores in the great shadowcast, clinging to whatever. Altogether, nuclear clouds, not the meteroric first or atomic last, but a blast offing of the future.
