in nature. However, Rishbeth and Kile did find rhizomorphs buried in the soil on inocula. Since the species doesn't produce rhizomorphs commonly in the nature, infected roots must come into contact with other potential hosts for infection to occur. So, root grafting provides an effective pathway for

Heterothallic species perform anastomosis when haploid monokaryon come in contact with one another. Anastomosis is the connection or opening between two things, in this case the mycelium. Mycelium is the vegetative part of the fungus that consists of hyphae. If the two monokaryons are sexually

compatible they form a clamp connection. This results in a mycelium consisting of dikaryotic cells. The dikaryon cells predominate in the vegetative phase. In the basidia karyogamy occurs before meiosis and then the formation of basidiospores. The basidiospores then infect the host plant.
