certainly be described as a new Cordyceps. Fortunately, in the 
present instance, it was gathered with numerous other specimens 
of Cordyceps dipterigena. 
The accompanying figures show normal and _parasitised 
specimens of Cordyceps dipterigena respectively. Fig. 1 is the 
normal fungus with the usual pair of perithecial stromata and 
the single conidial stroma, viewed from the head of the insect, 
and magnified four diameters. Fig. 2 is a parasitised specimen, 
viewed laterally, magnified six diameters; the perithecial stro- 
mata of the Cordyceps are hidden by the perithecia of the 
Byssostilbe, while the conidial stroma is encircled by a cluster 
of these perithecia. Fig. 3 is another parasitised specimen, in 
which external mycelium is almost completely lacking; the 
heads of the perithecial stromata are densely covered with the 
perithecia of the Byssostilbe, and a third cluster occurs on the 
insect between them. The stalks of the perithecial stromata in 
this latter example are short and are not seen in the figure; 
they do not bear perithecia of the Byssostilbe. 
THE GENUS CLADOSTERIGMA PAT. 
by dT. Pach, BAB Se: 
The type species of the genus Microcera, Microcera coccophila 
Desm., is parasitic on scale insects. Consequently it is of interest 
to ascertain whether the other species which have been assigned 
to that genus have the same habit, or whether they are really 
cogeneric with the type species. Several of these species have 
already been reviewed in the “‘Nectriae parasitic on scale 
insects” (Trans. Brit. Myc. Soc. VII, pp. 99, 100), but a few were 
not accessible when that paper was written. One of these in 
particular, Microcera Clavariella Speg., was considered a probable 
entomogenous fungus, as it was described as occurring on living 
leaves of Eugenia; and in response to my enquiry, Dr C. Spegaz- 
zini kindly forwarded me the type and other collections of that 
species from South America. 
Examination of the type specimen showed that its structure 
differed from that of Microcera coccophila, and that it could not 
be included in Microcera. It has basidia covering the entire 
surface of the synnema, like a Clavaria. And on further con- 
sideration it was evident that the fungus was identical with 
Cladosterigma fusisporum Pat., originally described as occurring 
on living leaves of a Myrtaceae, from Ecuador.
