“…The gross morphology and nuclear condition of these SSIs and the secondary mycelia they produced was normal. Parag (1962) reported that common-A heterokaryons of Schizophyllum commune are sometimes stable but have a distinctive 'flat' morphology.…”

Investigation of the breeding biology of the agaric Crinipellis perniciosa (causal agent of witches' broom disease of cocoa in South America) found that two distinct breeding strategies exist among the four known biotypes of the fungus, which are specific to cocoa (C-biotype), solanaceous hosts (S-biotype), Bixa orellana (B-biotype) and liana vines (L-biotype). The homomictic (primary homothallic) behaviour of the C-biotype was confirmed and single basidiospore isolates (SSIs) of the S-biotype and B-biotype were found to behave in a similar manner. The mycelia of most SSIs of the L-biotype did not bear clamp connections and pairings between sibling SSIs established that an outcrossing mechanism under the control of two unlinked mating type factors was operating (i.e. bifactorial heterothallism). These matings also suggested that one of the mating factors has a twogene structure. The occurrence of bi-and trinucleate basidiospores and SSIs bearing true or false clamp connections suggests that the L-biotype exhibits a limited degree of secondary homothallism.

“…An hypothesis assuming such defects in the " canalisation" system of monokaryotic mycelia of S. commune is supported by the fact that certain monokaryons that do not accept migrating nuclei of compatible strains (unilateral dikaryotisation) will do so readily if mated very young, as germinating basidospores (Parag, 1962).…”
