On fading leaves, tent and stems of Palms, California 
a Herb. no. 2546!); on eset leaves of Chamaerops 
black wee of te hecho The external appearance resembles 
that of Placosphaeria Bae nage Urticae, Sacc. = Melasmia 
Urticae, Grove in Journ. Bot. 1918, p. 319, but the pustules 
are much larger. Each is imperfectly divided into several 
chambers, which are filled with a colourless mass of spores. 
The outer wall of the pustule is many cells thick, the outer layer 
and the inmost of which are dark-brown (cells 5-6 » diam.), 
the middle part being paler. The three layers A, B, and C, are 
shown in vertical and horizontal section in fig. 1, a and b; 
A = the altered black epidermis, B = the less altered cortex, 
transition; at the base only C is present. The part of the 
matrix occupied by the fungus forms a large black patch extending 
for a considerable distance; the older pycnidia fall out of this, 
and leave pale roundish pits or scrobiculations.

Berkeley’s original specimens were examined; as is well- 
known, they are merely young D. malorum, Fckl. They yielded 
abundant colourless spores, and many tinged’ with dilute brown 
(‘‘ sporulis chlorino-hyalinis ’’), but also not a few which were 
decidedly of a Diplodia brown, though none were found with 
a septum. They do not differ in any respect from those of 
Peck, and correspond in all their characters with the ordinary 
young Diplodia. It should be noticed that D. malorum, Fckl. 
is merely a synonym (two pages later) of D. Pseudodiplodia, 
Fckl., but the former name should be preferred, since the latter 
is inappropriate and inconsistent—a true Diplodia cannot be a 
** false-Diplodia.”’
