Recall Knowledge DC 27 (nature)
Disable DC 27 survival (expert) to remove a 10-foot-square patch of ash web without triggering the spores

This dangerous sooty black mold readily releases its toxic spores when disturbed. The entire swath of fungus in area B2 is a single organism. There are nine 10-foot-square patches to remove, but the whole organism dies once it takes enough damage.
