I've always heard them informally called "umbrellas" or "water park 
umbrellas". If someone mentioned "water mushroom" or "water umbrella" in 
the context of a water park, I'd immediately understand either term. 
However, out of context, I would assume the former is a variety of 
mushroom and the latter refers to a waterproof umbrella, as opposed to a 
parasol.

I'm almost tempted to call it an amenity=shower -- that is, if one is 
expecting a chlorinated shower. ;-)

More seriously, these devices are usually part of a splash pad. There 
are two common, documented tagging schemes for splash pads:

* amenity=fountain fountain=splash_pad [1] 1,355 occurrences
* leisure=playground playground=splash_pad [2] 1,083 occurrences

It seems to be pretty common to map a typical fountain as a 
natural=water area with an amenity=fountain node at the nozzle(s). I see 
this most often on larger ponds with multiple nozzles or a nozzle that 
isn't at the center.

If this is acceptable, then one option for your example would be to map 
the splash pad as a leisure=playground playground=splash_pad area and 
place one or more amenity=fountain nodes inside it.

Apart from prominent water park features like umbrellas, micromapping 
the layout of a splash pad or other fountain seems akin to 3D building 
mapping. *ducks for cover*
