Pure synthetic cultures of Physcia (^Xauthoria) parietina were begun in August J 884 on fragments of bark. In October 1886 the thallus was several centimetres in diameter, and some of the lobes were fruited. Physcia stellaris was also grown on bark; in one case both thallus and apothecia were developed.
