This interlacement formsa fleecy cloud in the urine, which gradually rises to the surfaceand forms an islet or patch of mould from which spring theascending stems of the aerial fructification. The latter consistof hollow filaments rising from the thallus, which divide attheir extremities into two or three branches ; these againsubdivide into a number of digitate projections so as to forman irregular tuft or head (Fig. 38). The digitate projectionsare filled with sporules, and eventually burst, giving exit tothe sporules, which then fall into the urine below, and collectinto an amorphous-looking deposit at the bottom of the growth of this vegetation in urine has been admirablydescribed by Hassall (Med.
