The septal pores of homokaryotic and dikaryotic mycelia of Coprinus lagopus have the complex structure characteristic of certain Basidiomycetes. The edge of the pore is thickened and covered on either side by a dome‐shaped, perforated, membranous cap. However, in heterokaryotic mycelia in which nuclear migration was believed to be taking place, in addition to the complex pores, simple pores were also observed as well as various intermediate stages interpreted as steps in the breakdown of complex to simple pores. The simple pores may facilitate nuclear migration.
