[4] This name, however, was later deemed illegitimate under Article 53.1 of the International Code of Nomenclature for algae, fungi, and plants, due to prior use in botany.
[5] The Nomenclature Committee for Fungi determined that the similarity between Phyllocratera and Phyllocrater constituted a case of parahomonymy, leading to its invalidation.
Their thalli (lichen bodies) are thin, grey-green, and slightly crust-like, forming a close bond with their green algae partner, Phycopeltis.
The reproductive structures (the perithecia) are black and wart-like, with a broad base and a small pore at the top for spore release.
The spores themselves are transparent, have multiple internal walls, and are shaped like elongated ellipses with a slight pinch at the middle.
