only seen when the outer layers of the bark are peeled off. Sporules 
elliptical, uniseptate, not constricted, brown ( , 016- , 022 X *009-*01 
mm.). 
On stems and branches of Cistus laurifolius. Pleasure grounds, 
Kew. 
Hendersonia Tamaricis, Cooke. 
Perithecia loosely gregarious, covered by the elevated cuticle, 
subglobose, scarcely papillate. Sporules elliptical, slightly attenu- 
ated at each extremity, triseptate, not constricted, clear brown 
(•018--02 X-007 mm.). 
On branches of Tamarix gallica. Kew. 
var. Elaeagni, Cooke. 
Perithecia rather smaller, and more closely gregarious. Sporules 
the same. 
On branches of Elceagnus. Kew. 
This form differs so little from that on Tamarix , that it can have 
no claim to be considered a distinct species. 
Hendersonia ambiens, Cooke. 
Gregarious, covered by the elevated cuticle, which is at length 
perforated, globose, shortly papillate. Sporules narrowly ellip- 
tical, triseptate, not constricted, clear brown (*02 X -OOT-’OOS 
mm.). At first with sporophores of equal length. 
On branches of Acer dasy carpum. Kew. 
Camarosporium Staphyleae, Cooke. 
Scattered, covered by the bark, and concealed. Perithecia black, 
globoso-depressed, rarely slightly elevating the cuticle. Sporules 
elliptical, triseptate, one or other of the central cells transversely 
divided, not constricted, clear brown (.018-'02 X ’008 mm.). 
On branches of Staphylea pennata and S. trifoliata. Kew. 
What appears to be a variety of the same species occurs on 
slender twigs of Celtis. 
Camarosporium cistinum, Cooke. 
Gregarious, seated on the inner bark. Perithecia globose, black, 
with a conical ostiolum, which perforates the covering layer of 
bark, sometimes forming irregular lines. Sporules elliptical, elon- 
gated, triseptate, not constricted at the septum, with sometimes 
(but not constantly) one of the central cells divided longitudinally, 
brown (-015-'018 x -005-*007 mm.). 
On branches of Cistus laurifolius. Kew. 
Coryneum cistinum, Cooke. 
Stroma pulvinate, orbicular, convex, black, seated in the inner 
bark, somewhat gregarious, covered and wholly concealed by the 
outer bark, and only exposed when this falls away ; conidia lan- 
ceolate, obtuse at the ends, triseptate, but not constricted, clear 
brown (‘Ob-’Obb X *015-*018 mm.); pedicels hyaline, about the 
same length as the conidia, at length deciduous. 
On branches of Cistus laurifolius. Kew.
