Gargantuan Obsiditree

The Gargantuan Obsiditree split from its ancestor and achieved a truly massive size. Like its cousin, the Obsidoak, it now has multiple clusters of spore pods; however, instead of scattered throughout, these are associated with specific major branches. It is so tall that its spores have become aeroplankton, allowing it to be present in disconnected habitats all over the supercontinent.

The Gargantuan Obsiditree is more common in its rainforest and riparian habitats than in the slightly drier woodlands. Though its black pigmentation would normally make it vulnerable to overheating, it is able to mitigate this with evaporation--convergent with Obsiditall, the Gargantuan Obsiditree, too, has gained the ability to sweat. Similar to mammalian sweating, the evaporation of its “sweat” takes excess heat with it. Its leaves are shed regularly, especially in the temperate parts of its range, covering the forest floor in leaf litter. It can take centuries to reach full size and can live for thousands of years.
