Knowledge check to identify a Brown Mold

[Truth Seeker]

Hello,

The Brown Mold is categorized as a CR2 Special Hazard. Knowledge Skill description indicates that a Knowledge (Dungeoneering) roll was required to identify an Underground Hazard while a Knowledge (Nature) was needed for a Natural Hazard. What Knowledge check would apply to identify a Special Hazard such as the Brown Mold ?

Thanks!

Under Slimes, Molds, and Fungi it states that "For purposes of spells and other special effects, all slimes, molds, and fungi are treated as plants".

Plants are typically identified with Knowledge (Nature). A think a standard DC of 10+CR would be reasonable (DC 12 in this case).

Edit: looking at a module I recently ran with Brown Mold, they have it listed as a DC 17 Knowledge (Dungeoneering) check. Presumably 15+CR because of rarity.

Module name spoiled to protect the innocent:

Godsmouth Heresy.

I think it should be 12 know (nature), but it is a threat in dungeoneering so DC 17 for Know (dungeoneering).
