Tear of the Goddess specifies that you generate mana (a) when you activate an ability or (b) when you expend mana. Toggled abilities do not count as "activations" - so Poison Trail will only generate charges when Singed expends mana. Manaless abilities still count as "actives" and so still generate mana - as I'm sure you've seen Nidalee's spamming cougar abilities to charge it.
