Diagnosis (modified after Bromley & d'Alessandro,1987) — Thin tubular boring networks showing irregularly repeated branching and anastomosing in all directions. Rarely more than a few millimetres between branches, but density of ramification varies. Boring diameter typically ranges between 0.10 and 0.25 mm. Course almost straight to sinuous or contorted. Apertures are numerous.
