Capnodium brasUiense Puttem. Mycelium crustaceons, broadly effused, hyphae 
greenish black, cells unequal, constricted at septum to 5 to 12 ll. hyphal 
cells forming chains of almost cubical conidia 4 to G ,u in diameter (Torula

than the rest. 13 to 16 by 5 ft in diameter. On Hevea and coffee, Amazon 
Valley. 
C. javanicum Cke. On insects on leaves. Dutch East Indies. 
C. lanosum. On leaves, Amazon Valley. Orient. 
Catacauma Hubert (P. Henn. i Theiss. and Syd. Stroma subepidermal, form- 
ing in yellowish or yellowish brown areas, appearing first on the death of 
the hypophyil as a thin brownish or blackish crust covering or encircling 
the discolored area, later anastomosing in radiating or concentric broad 
black bands or becoming confluent to form a conspicuous black stromatic 
layer from 20 to 60 ft in thickness : hypha? of stroma 6.9 to 10 ll broad, 
parallel to each other and at right angles to the surface ; perithecia single 
or crowded in large masses, ostiola conspicuous ; asci clavate, 8-spored, 60 
to 95 by 15 to 22 ll : spores biseriate or obliquely uniseriate in lower part 
of ascus. ovoid to elliptical, hyaline. 15 to 20 by 8 to 11 /a : conidia hyaline, 
unicellular elongate, 12 by 3 ll. On leaves of Hevea brasiliensis, H. discolor 
(Ule. Herb. Brasiliensis No. 3048), H. pauciflora (Ule, Mycoth. Brasiliensis 
Xo. 73) II. nivea, and on other species noted in the herbarium at Para. 
This fungus was first named and described by Hennings in 1900 from 
material collected in 1898 by Etuber (No. 16) near Para on young H. brasU- 
iensis. In 1904 Hennings again recorded it from Para as parasitic on 
leaves of Hevea sp., with an illustration and description. In the same 
year he reported collections by Ule on H. brasiliensis from Manaos (July, 
1900. and Jan.. 1901), at Santa Clara on the P.io Jurua (Oct.. 1900). and 
at Sao Joaquim (Jan.. 1902) and Jurua Miri (June. 1001 > on the Rio 
Negro in Amazonas. Petch contributed an article on the fungus in 1908. 
In the same year Renin, from material collected by Baker on H. brasili- 
ensis at Para, described and issued the fungus in his exsiccatum. Cook 
compiled the existing information on the fungus in 1913. Vincens in 1915 
described and illustrated the fungus in considerable detail. In 1915 Theis- 
sen and Sydow placed the species in their new genus Catacauma. estab- 
lished in 1914 on Dothidia exanthematica Lev. (in herb.). The material 
examined by these authors was Tie. Mycoth. Brasiliensis No. 73 on H. pau- 
ciflora collected at Manaos in 1901 : Renm, Asc. Xo. 1TS6 on H. brasiliensis 
collected by Baker in 1908, and on H. nivea. The species forms a true 
stroma, and for this reason it is separated from Phyllachora, which in 
the case of the true species including the type of the genus does not have 
a stroma. A marginal conidia! stroma is present, but in many of the Dothide- 
aceae such conidial stages have been entirely lost, at least to all appear- 
ances 
Cephalosporium lecanii. Parasitic on scale insects on green stems and leaves, 
Ceylon and Amazon region. 
C. sp. Found in moldy rot of tapped surfaces. Malay Peninsula. 
Ceratosporium productum Petch. On dead branches, Ceylon. 
Cercospora li<r<<i< Vincens. Parasitic on leaves. Brazil. Conidiophores ir- 
regular, geniculate, clustered on small reddish spots. 20 to 25 u high, 3 
to 5 ft in diameter: conidia oval or fusiform. 2 to 5 septate. 25 to 50 fi long. 
3 to 5 ft in diameter, on leaves. Vincens found it in association with Cata- 
cauma huberi.
