Pocheina is a genus of cellular slime molds from the Heterolobosea group . The species of the genus are often found on wet bark under moist conditions.

Description and life cycle

The stalked, pink-colored sorocarps are composed of several rows of encysted and still viable single cells. The spherical spore bearing measures around 100 micrometers in diameter, the stem is of the same length.

Spores with only one nucleus or the encysted cells of the stem germinate and then release amoeba of the Limax type (i.e. of a cylindrical, non-flattened shape). However, the cells should be divided before the Excystierung may either two zweigeißlige protoplasts or a binuclear protoplast produced from which after the scourge development through cell division produces two zweigeißlige amoeboflagellate cells.

The genus was first described in 1961 by Alfred R. Loeblich and Helen Tappan . The type species is Pocheina rosea, first described by Leo de Cienkowski in 1883 as Guttulina rosea . Pocheina includes only two or three types, including:
