a culture I made, it grew in a very straggling fashion, and budded 
off a succession of spores from the tips of the branches. It has 
been recorded on decaying leaves and stems. Another species, 
F. commutatum Sacc. (plate 1X. fig. 2), is new to this country ; 
it falls under Saccardo’s group “sporodochia laxa, effusa, 
byssina.’ On clover seed it hardly looked like a /usarzum, 
but on a culture plate it formed lax cushions; the spores are 
three-septate and measure 20—25 X 4—5p. There is one 
difference between this species and the type in that the sporo- 
phores are septate, otherwise Bonorden’s drawing exactly repre- 
sents the habit of the fungus, and “ sporophoris continuis” may 
not be a constant character. . 
There are two forms of Hyphomycetes that have puzzled me a 
good deal. The first grew on a seed of Festuca pratensis and 
from the character of the hyphe and spores | have placed it in 
the hitherto monotypic genus Langlozsuda of Ellis and Everhart. 
The hyphe are much larger, the spores also are larger, more 
deeply coloured, and not so pear-shaped as in the American 
species, L. spinosa. I therefore consider it to be a distinct 
species, and have named it L. macrospora (plate IX. fig. 3). I 
fear the genus, however, rests on too narrow a foundation of 
divergence from other forms, and the species might have been 
included in Acremonzella. Vhe other specimen has baffled all 
my attempts to place it under any recorded genus. It is in 
form and habit something like a Stemphylium, and, but for lack 
of colour, I would have classed it under that genus. There is 
only one genus recorded under the group Mucedinee-hyalo- 
dictyez, and it is entirely different in torm from the fungus | 
have been dealing with. I have been compelled to establish a 
new genus, which I have named Stemphyliopsis g. n., to connect 
it with its nearest ally among the Dematieze the species I have 
called heterospora, plate IX. fig. 4. The spores are exceedingly 
varied in form and size, and are borne at the tips of short 
branches from the main hyphe. They are warted when mature, 
and the whole plant remains colourless after some weeks’ culture. 
I succeeded in reproducing it on a gelatine plate. I got the 
original specimens on turnip seed and on clover seed. 
The Mucorinee are the sole representatives of the 
Phycomycetes that have appeared in the germinating case, and 
Rhizopus nigricans Ehrenb. most frequently of all. It grows on 
any kind of seed, though on the whole it is partial to the grasses. 
It spreads very quickly, and in time extends over the whole 
available space. I have found another form also with rootlets 
somewhat similar to those of RAzzopfus, which on that account I 
have included in the same genus. The sporangiophores rise 
singly from the runner-like hyphe, and near the top they form
