Diagnosis
ReferenceDiagnosis
F. Debrenne et al. 2015Encrusting, domelike cup; upper wall (interpreted as outer) with pores regularly arranged but not at each intertaenia; pores commonly produced as chimneys; lower (possibly inner) wall rudimentary; dictyonal or more probably pseudotaenial network. [Atypical cup shape does not provide certainty as to which wall is outer and which inner, and nature of inter- vallar elements and accepted inner wall remain doubtful.]
