Taxonomic remark Terrestrial group, sometimes suggested to have algal affinites; more recently at least some elements appear to be fungal, refer Edwards & Axe, 2011, however Smith & Butterfield, 2013 suggest a red algal affinity. Edwards et al., 2018 reaffirm their belief that Nematothallus represents a lichenised fungus. Speaking of Prototaxites, Nelsen & Boyce, 2022 state: We argue that the weight of the evidence argues against interpretations as an agaricomycete sporocarp or ascomycete lichen association and that while the taxonomic identity remains unclear, we suggest that if Prototaxites was indeed of fungal origin, it may represent part of an extinct lineage lacking extant descendants.
