Taxonomy In his overview paper, Morton (2007) separated off a family Penicillidae for Penicillus, Brechites, Foegia, Nipponoclava, Kendrickiana and Humphreyia, from the Clavagellidae containing the extinct genus Clavagella and the extant genera Dacosta, Bryopa, Dianadema and Stirpulina. The tube or "crypt" in which these taxa live in the sediment, or attached to shells, etc., is formed in quite different ways in the two families, and Morton (2007) suggested that they evolved from distinct lyonsiid ancestors. This view is disregarded by Huber (2010) who finds this splitting exaggerated and considers all the Clavagellidae sensu Morton (2007) as subgenera of Clavagella Lamarck, 1818 [details]
