Mushroom Leather to Mushroom?

The Mycoworks company is producing 'mushroom leather'. This should more properly be called 'mycelium leather', as the material is cultured from the subterranean tubes that are the main manifestations of fungi (https://www.theguardian.com/science/2021/dec/02/californian-firm-touts-mushroom-leather-as-sustainability-gamechanger). 'Mushroom leather' can be grown in trays, within a few weeks. It can be engineered to resemble calfskin or sheepskin. The material out-performs animal leather in terms of strength and durability, so it can be used to make shoes, handbags etc. 'Mushroom leather' also has the big advantage of having a much smaller carbon footprint than traditional leather. Its use could consequently help to limit climate change. It has been suggested that 'mushroom leather' is a 'vegan' alternative. This is also a misnomer, as fungi are not plants. This is a very interesting development. Human logic, however, maintaining that the Animal Kingdom is sacrosanct, whereas Plants and Fungi (also fellow Eukaryotes) are infinitely exploitable, seems a bit of a stretch.
