- Diagnosis
- Loose plexus of non-septate tubular cells of two types; the smaller (7-(8-5)-10 ft in diameter) having smooth walls, the larger (2-(18)-24 fi in diameter) having thin walls with conspicuous spiral thickenings. Branching of both types localized in " branchknots". Tubes showing no preferred orientation, but more closely compacted where they abut on a structureless clear zone which may represent a natural surface layer. Part of an organism of unknown form and size. Associated fragments of smooth, thick-walled diffusely branching tubes up to 56 n in diameter and spores ca.27 /< without triradiate markings.
