\)v most reliable in distinguishing species are found in the antheridium. The number of rows of antheri- 
dial cells, and the number of cells in each row, are apparently very constant; variations in these respects 
in a given species, occurring rather exceptionally. In some forms the antheridium may be the most 
complicated male organ that occurs in the whole group, with the exception of that in Ewnonoicomyces 
and possibly in some forms of Ilaplomijces; since, as in E. Catoscopi, there may be over fifty antheridial 
eells in a single antheridium. In certain other species, nevertheless, this number may be reduced one 
half or more, as in E. Evprorfi or E. spinosns. 
The structure of the antheridium appears to correspond in general to that of most of the other com-

ven five, on either side; and their bases being external, they empty by short necks into an interior cavity, 
which connects directly with an efferent tube, through which the antherozoids are discharged in large 
numbers. The structure is closely comparable with that of Haplomyccs, in which, however, the an- 
theridia, not being separated by a sterile external marginal cell, surround the antheridial cavity com- 
pletely. 
An 
winch renders a very careful comparison of characters necessary in order to distinguish them. It should 
be noted that the spores, in many of the species at least, are peculiar in possessing a bluntly rounded apex, 
m place of the usual acuminate tip. The inner lip-cell is in general more or less distinctly modified, 
form 
nence, as in figs. 28 and 36. The characteristic spine which persists in some species at the tip of the 
antheridnim (Figs. 10 and 19) represents the apex of the spore, and is primarily terminal, as in Stig- 
watom !F es where it is almost invariably present. The ascogenic cells may be somewhat peculiar and in

Were do not appear to be more than four, or possibly two, in some cases. The species appear to be very 
generally distributed and the hosts are in all instances beetles belonging to the Carabid*.
