Summary
Six classes of hyphal fusion are found in Coprinus lagopus. The frequency of fusion is temperature dependent with a high Q10. The frequency of fusion is quite high in non-compatible matings, particularly in certain strains, but significantly lower in common-B matings. The effects of the incompatibility factors on fusion frequency in compatible and common-A matings are less clearcut. A minor role in regulating fusion frequency is attributed to the incompatibility factors. A lowered frequency of fusion may result from the formation of relatively inactive hybrid enzymes.
