Radicoida
Huge, incredibly resilient organisms that establish massive underground root systems. These roots extend several hundred meters underground, securing the host organism in place and accessing underground aquifers and nutrient sources in a wide variety of soils. The type of soil, climate and atmosphere is believed to influence certain characteristics of organisms, but key traits appear consistent. While they may share several attributes with fungi - deep roots, bioluminescence, spores, broad upper growths - they are technically a type of woody plant.
