Four hundred-million-year-old vesicular arbuscular mycorrhizae.
TLDR
The discovery of arbuscules in Aglaophyton major, an Early Devonian land plant, provides unequivocal evidence that mycorrhizae were established >400 million years ago and indicates that nutrient transfer mutualism may have been in existence when plants invaded the land.

Fossil arbuscular mycorrhizae from the Early Devonian
AbstractThe 400 million-year-old Rhynie chert has provided a wealth of information not only of early land plants, but also of the fungi that inhabited this paleoecosystem. In this paper we report t...

Fungal endophytes in a 400-million-yr-old land plant: infection pathways, spatial distribution, and host responses.
TLDR
The host responses indicate that some of the mechanisms causing host responses in extant plants were in place 400 million yr ago, and Anatomical and life history features of N. aphylla suggest that this plant may have been particularly susceptible to colonization by fungi.

The oldest fossil ascomycetes
TLDR
The oldest ascomycetous fungi with flask-shaped ascocarps in thin-section preparations of the Lower Devonian Rhynie chert of Aberdeenshire, Scotland are found, underscoring the diversity of fungal-plant interactions early in the colonization of the land.

Perithecial ascomycetes from the 400 million year old Rhynie chert: an example of ancestral polymorphism.
TLDR
The structure and morphology of the fossil fungus is compared with modern ascomycetes that produce perithecial ascocarps, and characters that define the fungus are considered in the context of ascomYcete phylogeny.

Sphenophytes from the Carnian (Upper Triassic) of Lunz am See (Lower Austria)
The sphenophytes in the Late Triassic flora of Lunz (Lower Austria) are revised and illustrated for the first time. Three taxa have been identified, i.e. Equisetites arenaceus, E. conicus and…
