Tylosis formation and fungal interactions in an Early Jurassic conifer from northern Victoria Land, Antarctica
PUBLISHED Well-preserved fungi occur in permineralized conifer axes from the Lower Jurassic of northern Victoria Land, Antarctica. The fungus is characterized by septate hyphae extending through the vascular ray system via penetration of cross-field pits. Tyloses are present in large numbers and mig...
