So in this first snapshot for the upcoming Nether Update we see two new fungi trees, each one coming from one fungi: the Warped Fungi and the Crimson Fungi.
When grown they both have stems and a foliage called wart. Now warped fungi has the warped wart, but the crimson fungi has the nether wart. This is a problem because this nether wart block is what you get from joining together nine nether wart plants.
What I think would be better is if we could keep the Nether Wart Block and change its name to Crimson Wart Block, and create a new block with a new texture for the Nether Wart Block.
