Palaeofibulus, gen. nov., a clamp-bearing fungus from the Triassic of Antarctica.
Mycologia 81: 622-626.
A clamp-bearing fossil fungus is reported from silicified plant tissues of early-middle Triassic age from
Antarctica. Palaeofibulus antarctica gen. et sp. nov. represents the third unequivocal clamp-bearing fungus
described from the fossil record. Specimens consist of a branched, septate mycelium and chains of thick-walled
dikaryotic spores or chlamydospores. Affinities with several present-day fungi are considered. The Triassic
fungus is most comparable to modern basidiomycetes, however, without documented basidia precise taxonomic
assignment remains equivocal and it is therefore suggested to be a 'conidial basidiomycete'. Ecologically,
this clamped fungus most likely represents an example of a generalized saprophyte.
