Description of the Plates.

PLATE I.—1. Photograph, natural size, of a stunted shoot, showing the stem and
petioles of the older leaves covered with fruit-bodies, and the
younger leaves, just unfolded, quite free.

         2. Photograph, natural size, showing two separated older leaves with
petioles covered with fruit-bodies.

PLATE II—1. Promycelia: (a ) x 350, showing promycelium divided into four cells,
each with a sterigma from which the sporidia have fallen off: (b )
x 150, showing two promycelia, with their stalks and the central
cells giving rise to them.

         2. Transverse section of leaf showing inception of fruit-bodies, x 150.

         3.Ditto at margin of area of invasion. At (a ) the intercelluiar spaces
are filled with mycelium: at (b ) the tissue is normal, x 150.

         4. Sporidia showing germination, and formation of secondary sporidia,
x 580.

         5. Photograph of transverse section of petiole, by Dr. D. D. Cunningham,
showing mature fruit-body (compare with DeBary's figure of
C. Rhododendri ).

         6. Photograph of cortical tissue of petiole by Dr. D. D. Cunningham,
showing aggregations of mycelium in intercellular spaces.
