Fungal remains in Early Jurassic woods from Carapace Nunatak. A. Wide hypha with branching narrow hyphae (arrow). Slide 274 (radial B1); B1, B2. Multiple focal planes of wide hyphae; note thin structure inside of wide hypha (arrow). Slide 30780; C. Degraded hyphae traversing between two adjacent tracheids with abnormal Y-branch (arrow). Slide 30780; D. Hypha traversing through pits (arrows). Slide 30780; E. Highly degraded tracheids in transverse section. Note starburst pattern in lumina from multiple, and coalescing, erosional cavities. Pattern is similar to extant soft rot fungi. Slide 30781; F. Prominent erosional troughs in adjacent tracheids (arrows). Slide 30781. Scale bars: 50 µm (A, E); 10 µm (B1, B2, C, D).
