A type of autophagy where cytosolic components are ingested by late endosomes, lysosomes or yeast-type lytic vacuoles by direct invagination of the compartment membrane without prior sequestration into an autophagosome. The engulfing membranes fuse, resulting in the lysosomal delivery of the cargo wrapped in a single membrane derived from the invaginated lysosomal membrane.
