Key points

Of 10 geographic strains of Flammulina velutipes, 4 were found capable of fruiting at 22 degrees C (Fr(H)) rather than at the typical 15 degrees C (Fr(L))
Crosses made between Fr(H) and Fr(L) monokaryons were never observed to fruit at 22 degrees C. However, some hybrids did fruit at the intermediate temperature of 18 degrees C when grown on appropriate substrates, indicating incomplete dominance of the low-temperature requirement
Analysis of progeny of five Fr(H) x Fr(L) crosses indicated that a minimum of two genes appears to control the requirement for fruiting at </=15 degrees C. The genes are not closely linked to either incompatibility locus
