Type.

Dictydium umbilicatum Schrad. (= Cribraria cancellata [Batsch] Nann. - Bremek.), designated by Martin (1949: 32).

Diagnosis.

Emerging plasmodium very dark brown to blackish, sometimes with purplish hues. Mature sporophores always sporocarpic, stalked, brownish, maroon to pink-purplish, with dictydine granules abundantly present both in the peridium and in the spore mass (attached to the spores or not), sometimes also present in the stalk.

Species included.

C. cancellata (Batsch) Nann. - Bremek. , C. mirabilis (Rostaf.) Massee , C. meylanii Brândza , C. purpurea Schrad. , C. rutila (G. Lister) Nann. - Bremek.

Nomenclatural notes.

We consider the name at subgeneric rank as accepted by Yamamoto (1998), where all requirements for its valid publication as a combination are fulfilled. Yamamoto (op. cit.) ascribed the authorship to “ (Schrad.) Pers. ” noting that in Persoon (1801) this group was referred to as “ Dictydia ”. Persoon (op. cit.: 189) indeed mentioned “ Dictydia Schrader ” referring to the group of species that were treated by Schrader (1797) as Dictydium , but there is no indication that Persoon accepted an infrageneric name for this species group and, in any case, such a name would be unranked and not compete for purposes of priority (Art. 37.3, ICN).
