Any ID on these critters ?

[gregzz4]

I have searched the web for umpteen hours ....

Flowers and Green Whiskers showed up about a week after adding the LR to the tank. It was cured for 3 months in the dark, but I understand how things can lay dormant forever ....
It's been maybe 3 weeks and they aren't spreading too fast, but I'd like to know what I'm dealing with

Some of the green "stems" have sprouted white "flowers" and one of my Astrea snails now has them for backpacking

There are 3 things I'm asking about;
-The Green Stems ( some with white flowers )
-The Green Flowers with White centers
-The White Flowers

Thanks for your help
