For optimal growth the plant has to be wet, and for any growth at all to take place at least some water must be present. This finding is in contrast to that of Lange and Bertsch (1965), who observed that certain lichens could absorb sufficient water vapor from air to achieve near optimal levels of gas exchange."]

Such a sheath may be the means by which the symbionts recognize each other. Hyphae of the mycobiont formed flattened appresoria as they grew over algal cells and in this way secured the autotrophic population necessary for the development of a lichen thallus."]

The same mycobiont did not associate with isolated of Pseudotrebouxia or Pleurastrum terrestre. "The mycobiont Lecanora chrysoleuca formed soredia with five isolates of Pseudotrebouxia and with one isolate of Trebouxia. Concentric bodies were seen in the hyphae of C. cristatella synthesized with the phycobionts of Cladonia boryi and Lecidea tumida." The results support the generic specificity of mycobionts for the phycobiont and the role of concentric bodies in development of the lichen thallus or synthesis of lichen substances.]

    Abstract: 12 figures. 1 table. ["Successful resynthesis of the Cladonia cristatella mycobiont with its normal phycobiont and with Trebouxia isolates from 12 other species of lichens all produced the characteristic depside barbatic acid as the major secondary product. No characteristic lichen products were found in cultures of the C. cristatella mycobiont either alone, under a variety of cultural conditions, or mixed with Pseudotrebouxia phycobionts under the same conditions that led to the successful resynthesis with Trebouxia phycobionts. The production of characteristic lichen products is affected primarily by the establishment of a successful symbiosis and secondarily by as yet poorly defined environmental factors. The formation of many characteristic lichen products may involve algal inhibition of fungal enzymes."]

Surprisingly, pannarin could not be confirmed in voucher materials of the natural source lichen, but the biosynthetic potential for this depsidone was proven for the species by a herbarium survey. The production of pannarin by the isolated mycobionts reported in the present study, however, unequivocally confirms Komyia and Shibata's hypothesis that typical lichen depsidones can indeed be synthesized by isolated lichen fungi with no assistance from the alga."]
