really deserve such an honour. In this category must 
he placed such universal fungi as Cladosporium herb arum, Asper¬ 
gillus glaucus, Eurotium herbariorum , and several others. If such 
species also as Merulius corium , Lycoperdon giganteum , Agaricus 
melleus , &c., are excluded there will still remain at least 150 
species of Yine Fungi. Then again the number of these may be 
considerably diminished by excluding those which manifestly can 
have no influence on growing vines, since these fungi only make 
their appearance upon dead and decaying stems. For horticultural 
purposes only veritable Yine diseases , in the strict acceptation of the 
word, possess any interest, and to these our observations must be 
chiefly confined. Perhaps now, with two monographs in existence, 
there will be less excuse than ever for exceeding such a limit, and 
it may be worthy of consideration whether it is advisable to con¬ 
tinue these communications under the new circumstances. 
Capnodium elongatum , B. and D.—This is one of the species 
omitted in the Austrian monograph, and probably also in the 
Italian. It nevertheless has been sent to us from the Depart¬ 
ment of Agriculture for the United States as having made its 
appearance on Yines and Fig trees to their detriment. In one of 
the early volumes of the Journal of this Society the Eev. M. J. 
Berkeley contributed a valuable paper “ On some Moulds referred 
by Authors to Fumago,” and in the course of this communication 
he demonstrated that the so-called species of Fumago , although at 
first appearing as a Cladosporium , afterwards became mixed with 
Macrosporium and other forms, and ultimately developed the 
elongated peculiar perithecia of Capnodium. The older authors 
confounded together under the name of Cladosporium fumago or 
Fumago vagans several distinct species of Capnodium , which were 
first separated and characterised in that paper. Undoubtedly 
Capnodium elongatum is one of the mature and complete conditions 
of Cladosporium fumago. 
These fungi cover the living leaves and young twigs with a 
thick black velvety or sooty stratum often seen in an imperfect and 
modified condition on the leaves of the Lime, and is found more 
perfectly developed on Orange, Willow, and now on Yine and Fig. 
These parasites consist of a dense mycelium of moniliform threads, 
usually brown, and from these arise large elongated, sometimes 
branched, perithecia, which contain the sporidia. The details of 
structure and development are so admirably set forth in the paper 
already alluded to that they need not be repeated here, except to
