This conference was held at Halle, East Germany in July 1977. The contrib- 

 utors to the volume came from North America, East and West Germany, Eastern 

 Europe and various other countries. The volume also contains a list of titles 

 of over 150 poster presentations from all over the world, with the affilia- 

 tions of the authors. 



Most of the 20 papers are brief to medium-length reviews of recent work, 

 while some are brief research reports. The large majority deal with higher 

 plants. All papers are in English and have been reproduced from typescripts 

 with minimal editing. The photographic illustrations are printed separately 

 on art paper.

This symposium took place in the U.S.A. in September 1977. It brought to- 

 gether a number of leading investigators in this field, whose contributions 

 are not just progress reports but lengthy reviews directed towards the fu- 

 ture. 



The incompatibility system of Sohizophyllum cOTmune is one of the few cases 

 in eukaryotes where the genetic basis of a regulatory complex involved in 

 differentiation has been uncovered. It is not surprising, therefore, that 

 four of the seven papers deal in one way or another with incompatibility 

 factors in the higher Basidiomycetes (not only S. commune) , some from a more 

 biochemical, others fran a more genetical viewpoint. Other papers deal with 

 meiosis and recombination, with sundry cytological and biochemical aspects 

 of morphogenesis, and with the regulation of fruiting. 



The volume is well produced and illustrated with clear diagrams and good 

 photographs .
