Does anyone know the name of the plants on the bottom (kind of shaped like a Reese's cup on a stem) that some local dive guides use to help with mask fogging during dives?

I've never seen a DM use anything like that. How would they do it and wouldn't it run counter to "look but don't touch" best practices?
 
I have seen them use sargassum and the berries floating at the surface. I don’t think anyone will miss it.
 
I've found that any plant that's green will work. Plucking one leaf is not going to destroy a reef, and a constantly fogging mask is a safety issue, particularly when you are responsible for other divers' safety.
 
Thanks all, I'm just asking for the name of the one that grows on the bottom shaped somewhat like a Reese's cup on a stem. Not advocating that anyone use it, just would like to know the name.

Edit: I've only seen these growing in the sandy areas, have not seen it growing on the reef.
 
Acetabularia?

It's technically a macro algae.....
 
Acetabularia?
Hmm, somewhat similar, but all the pictures I find of Acetabularia look more like an almost flat disc (perhaps with the edges lifted up somewhat like a martini glass), but the plant I am thinking of actually looks more like a solid Reeses cup (like an upside-down cone with the point cut off) on a stem. I'd say the cups are around half an inch (about a centimeter) deep.
 
I think it's flat top bristle brush. A few times and in a pinch I have needed to use the plant you refer to when I am really fogged up. Something went wrong with defogging on the boat. I find that carrying water around in my mask does better for me.
 
I would stay far away from using any ocean plant. The risk of fire coral or hydroids getting near the eyes makes me cringe. Spit is a much better alternative!
