simply “ spores.” The spore, on germination, usually produces a structure 
bearing lateral or terminal conidia. This body has been variously named 
(e.g., “ promycelium," “ germinal tu e," * hemibasidium," “ probasidium," 
“ basidium "), but in accordance with its significance in classification it 
should more properly be termed a “ basidium." Unfortunately, its behaviour 
is so varied in different genera and species as to make it impracticable

Members of the Ustilagineae are usually considered to be obligate 
parasites. Strictly this is nor the case, for Kniep (1921) has successfully 
grown Urocystis Anemones Wint. on culture media, the full cycle being 
completed thereon. Many species may be grown on media, where they 
produce abundant mycelium, but this is the first recorded instance in 
which spore-formation oecurred. en, too, at one stage in the cycle 
every species is saprophytie, producing probasidia and conidia (when 
these occur in the cycle) in the soil.
