This is Petrichor.

Petrichor is a dragon.

Or was a dragon.

In any case there's dragon in there somewhere but it's also technically fungus too.

Petrichor is part dragon, part dracopathenogenic fungi. Aka Dragon Cordyceps or Really Bad Luck.

It does smell strongly of damp earth and dislikes arid environments for obvious reasons; sticking to foresty places where it can lay down and soak up nutrition from the leaf-litter-laden floor. Tropical forests are preferred for their almost constant humid, warm temperatures but if persued it will flee and reside in temporate deciduous woodland.

Petrichor doesn't really need to eat as the fungus has claimed most of it's inner workings and trained them into spore-making apparatus, though if it cannot find the right spot to settle in it will ingest plant and animal matter to provide an internal compost for it's companion.

Although winged, Petrichor seldom takes flight because it's a labour-intensive process and it's not really built to be a graceful flying beast. It will take to the wing under duress but even if it does NOBODY WANTS THAT because it's wings are used to store spores and disperse them, much like a mushroom's gills.

Petrichor doesn't remember what it was before it was a fungus monster, nor does it really seem concerned with finding out. It is alive and it has stuff to do, no time to dwell on the past.

The spores from Petrichor can cause allergic reactions in mammals, is potentially lethal to birds and can parasitise other dragony things. In humans it most often causes chest infections and laboured breathing.

If you can tolerate or have a way of avoiding the spore-cloud (or Petri isn't shedding heavily) you may find that it is very amicable and conversational; curious about the rest of the world but not overly nosy. You'd have to really jab at it to make it mad.

I saw this thing in a dream and I'm blaming Amagire.
