VESICULAR‐ARBUSCULAR MYCORRHIZAE FROM THE TRIASSIC OF ANTARCTICA
Silicified roots from the Triassic of Antarctica show features of extant vesicular‐arbuscular mycorrhizae (VAM). Nonseptate fungal hyphae occur within and between well‐preserved parenchymatous cells of the central cortex. Terminal and intercalary swellings comparable to chlamydospores and vesicles a...
