Brood bodies are polymorphous and variously located. In their simplestform they are deciduous rhizo-protenemata, which appear in clusters on stems,often on midveins, as in Plciy;iotliccinm Roeseautim. They are, however, usuallymore complex in structure, and are sometimes borne on specialized stems andbranches, the pseudopodia, as in Aulacom)num paliistre; or in a cup-shaped in-volucre, as in Georgia pelliiciild; or on rhizoids (Brutknollen), as in some of theBarbulas; or on the excurrent costa, as in Ulota pliyllmitlui; or on the para-physes, as in Pottia lipcirui; or on the upper surface of leaves, as in Torlulapapilloma; or on both surfaces, as in Orlhotriclitim LyeUti; or in fasciculate clus-ters on the midrib at the base
