Apothecia (apothecium plur., 1988 ); however, there are also field isolates with dual mating phenotypes ( Faretra and Pollastro, 1996 ; van der Vlugt-Bergmans et This form of sexual reproduction in fungi is called conjugation (although it differs markedly from conjugation in bacteria and protists), giving rise to the name “conjugated fungi”. The hyphae that help form the podetia are formed from generative tissue. A taxonomic study of Peltigera in South Korea was performed. If the ascocarp is in a bowl-like structure it is known as apothecia.3 24. In this photo of a species of Peltigera the apothecia are the dark brown areas on the upright parts of the thallus. There are about 40 species in Parmelia. These spores infect and kill emerging leaf shoots, causing the shoot blight (primary) phase of the disease.
