spores are stellate, whilst in Pestalozzia they are septate, with a 
permanent peduncle, and crested above with two or three hyaline 
appendages. 
The Zorulacet externally, and to the naked eye, are very 
similar to the black moulds, and the mode of dissemination will 
be alike in both. The spores are chiefly compound, at first 
resembling septate threads, and at length breaking up into

joints, each joint of which possesses the function of a spore. In 
some instances the threads are connate, side by side, as in Zorula 
hysterioides, and in Speira, being concentrically arranged in 
laminz in the latter genus. The structure in Sporochisma is 
very peculiar, the joints breaking up within an external tube or 
membrane. The spores in Sporidesmium appear to consist of 
irregular masses of cells, agglomerated into a kind of compound 
spore. Most of the species become pulverulent, and the spores 
are easily diffused through the air like an impalpable dust. 
They form a sort of link between the stylospores of one section 
of the Coniomycetes, and the pseudospores of the parasitical 
section. 
PsEUDOSPORE is, perhaps, the most fitting name which can be 
applied to the so-called spores of the parasitical Coniomycetes. 
Their peculiar germination, and the production of reproductive 
bodies on the germ tubes, prove their analogy to some extent 
with the prothallus of other cryptogams, and necessitate the 
use of some term to distinguish them from such spores as are 
reproductive without the intervention of a promycelium. The
