Quote from"Saproling" seems to be a generic term for small plant/fungus creatures rather than a specific species.
Indeed what a Saproling is varies from plane to plane - sometimes even within a plane; on Ravnica in the old days Saprolings differed from guild to guild; Selesnya Saprolings are small creatures consisting of vines wrapped around crystals (as can be seen in the artwork) - the vines are based on plants which is why the Selesnyan Saprolings use seeds and pollen; Golgari Saprolings with the guilds focus on lightless subterranean rotfarms are classical fungal beings; Simic Saprolings are open to interpretation, though they are cyan/green-blue globules and seem to consist entirely of their trademark Cytoplast.
Guildless Saprolings could follow either style guide or none at all.
Remember: A Saproling doesn't need to be fungal. If anything its root tells us more about the fact that it likes death and decay. It can be (and sometimes is) a plant and apparently sometimes part gem.

Now you don't only seem to have a problem with Saprolings being not depicted fungal enough, but with Saprolings depicted too much like a Fungus. For example the "earthstars" are not there for there own sake. Those are the Saprolings that Vitaspore Thallid tosses around. Look at the mechanic and art and tell me that "every now and then it throws a new creature onto the field" isn't what the Thallid mechanic is actually reads like.
You can see similar depictions of Saprolings on Thallid cards again and again e. g. a big "white" Thallid in front of a few smaller "green" Saprolings on Pallid Mycoderm; maybe now you also understand the boring palette of colors: When an artist gets told to paint a "green" Fungus it will end up being green more often than not.
