Common Hyphae

Currently, there are four types of mushroom in Minecraft, but only two "hyphae" blocks.  For those of you unaware, "hyphae" blocks are nether mushroom stem blocks with the "bark" texture on all six sides, sort of like the ones for Overworld trees.  The only problem is that the hyphae does not exist for the Overworld mushroom stem, one of those annoying inconsistencies that go unnoticed for years to come.  Let's not let that happen, and convince Mojang to add a "common" hyphae for consistency's sake.
