Here's an almost complete list for you:



Almost complete, because there are "nature" gods who don't support Druids. This is just a list of gods who do.

Dumathoin created a paradise under the mountains for the shield dwarves when Moradin named him their protector. He shaped natural caverns of great beauty, studded with rich and beautiful deposits of shining metals and glittering outcroppings of crystalline gems. He was angered when the dwarves began to mine the mountains, destroying the beauty he had created. Dumathoin was pleased, flattered, and a little awed, however, when he saw the finely Grafted items the dwarves produced from the ores they had mined. He no longer objects to tunneling, mining, or the collecting of treasures underground.

The Silent Keeper frowns, however, on clumsy or crude rockcutting that does not smooth the earth, follow the natural flows, and highlight the individual features of the rocks. Cutting that causes cavern collapses and floodings are even less to his liking, and he is openly angered by those who pillage. Pillagers, in Dumathoin's eyes, are beings of all races who take the earth's riches away (in other words, to the surface) for unfair or selfish purposes, taking more than their share and leaving rubble and other messes in their wake.

Seek to enhance the natural beauty of Dumathoin's gifts and go with, not against, the contours of the deeps.

Abide not undead creatures, especially those that take the form of dwarves, thus mocking the creation of Moradin.

Priests of Dumathoin seek always to uncover the buried wealth of the earth without marring the beauty of the ways beneath the surface or being overly greedy. ... They work to clean up the rubble of mining, to grow and put in place luminous fungi and edible deep-mosses, and to direct water through the earth to best serve the underlife that includes, of course, dwarves. Priests of this faith are always hunting for new veins of ore, new sources and species of useful fungi ... They can also find water, veins of ore, and cracks or fissures that provide ways out, or can be mined to yield a way from one cavern to another.

Gray Druid

The rare gray druids inhabit and tend the shadowy realms of the hidden life that exists without
sunlight—fungi, molds, and slimes—and the nocturnal creatures that dwell in lightless, subterranean
realms. Gray druids are more closely associated with the earth than with other elements of Nature.
While many of them live in underground caves or ruins (especially in the Underdark), they are found
any place fungal life grows abundantly, either above or below ground. Gray druids tend to oppose
dungeon delvers, especially dwarves, who they believe defile and exploit the underground
environment. They have very good relations with deep gnomes and passable relations with drow,
who they feel show more appreciation of the beauty of the Underdark than most dwarves or men. But
the gray druids don’t always oppose surface dwellers. Suppose a maze of caverns has developed a
complex ecology: fungi, slimes, rust monsters, subterranean lizards, purple worms, and so on. Then an
evil wizard and his ogres move in and begin “clearing” the caverns, destroying the monsters in
preparation to establish an underground stronghold. In this situation, the gray druid might recruit a
party of adventurers — not to loot the caverns, but to defeat the wizard’s forces—and in so doing,
save the local ecology from destruction.
