bear circular brown spots exactly resembling those figured by 
Patouillard. Similarly, the description of the immersed stroma 
as concolorous with the synnemata in the one case, and black 
in the other is also to be attributed to a difference in the stage 
of development of the specimen examined. 
The synnemata may be short and forked towards the apex, 
or forked at various heights in stag’s horn fashion. This is the 
condition figured by Patouillard. But in many cases branching 
occurs at the base only, so that the free clavae are long, up to 
Imm. high, and slender, not inflated above; and the cluster 
has then quite a different appearance, especially as the clavae 
then become variously curved in drying and resemble, at first 
sight, extruded tendrils, rather than stilboid synnemata. 
The dry clavae are subtranslucent, horny-looking, and brittle. 
They do not swell up in water, and are probably more correctly 
described as waxy than as gelatinous. The basidia in the 
specimens examined were clavate or cylindrico-clavate, and it ° 
would appear that either the branched sterigma is evanescent, 
or that some of the basidia may bear only simple, rather blunt 
sterigmata. 
The chief difference between the two descriptions lies in the 
characters given for the conidia. Mucrocera Clavariella was 
said to have septate spores, and the specimens examined showed 
fusiform or clavate spores, straight or slightly curved, acute at 
at the tips, I-3 septate, I5—2I x 2-2:5, appearing rough when 
stained with iodine. The spores were not abundant. Clado- 
sterigma fusisporum was said to have fusiform, continuous 
spores, but as they were described and figured as multiguttulate, 
it is probable that they were immature. A more serious differ- 
ence is the measurement given by Patouillard, viz. 16-20 x 5-6, 
which indicates a much broader spore than that found in Micro- 
cera Clavariella by Spegazzini and the writer. Patouillard’s 
figures show a ratio of length to breadth, 11-5 to 2, and g,to 2°5, 
but even that is greater than in the available specimens of 
Microcera Clavariella. 
However, the identity of habitat and structure of the two 
species would appear to make it improbable that they are 
distinct, in spite of the discrepancy of the spore measurements. 
Microcera Clavariella is certainly Cladosterigma, and it does not 
appear to be different from Cladosterigma fusisporum. The 
species must therefore be known as Cladosterigma Clavariella, 
and the genus Cladosterigma must be included in Stilbaceae- 
Phragmosporae, not in Stilbaceae-Amerosporae. 
Three species of the same general structure as Cladosterigma . 
have been found in Ceylon, all of them parasitic on insects. 
They differ, however, from Cladosterigma in having simple,
