The first infection is often on the primary leaves. The fungus is seed borne and thus also causes [...] two-celled conidia are exuded. Secondary infection is by splash dispersal of these conidia. There is no known sexual stage. Ascochyta fungi develop most

Dwarf bunt

It is a fungus known to cause the smut disease TCK smut in soft white and hard red winter wheats, as [...] on all spikelets, showing the bunt (smut spore) they contain, which is larger than a normal kernel. The bunt balls are grey-brown. They rupture at harvest [...] healthy kernels, which in turn become a source of disease in the next season. The optimum temperature for germination is 3-8 °C and it takes three to ten weeks
