Hi Dirk

in einer Doktorarbeit über Cantharellus cibarius werden 14 cm/Jahr für den Pfifferling genannt:

"The optimal growth of C. cibarius mycelia in vitro was 0.5 mm/day (Paper II-III). If natural growth occurs during April-September and at the same rate as under lab conditions, radial growth should not exceed 9 cm/season (considering the lower temperatures, probably less). However, field observations, based on occurrence of fruit bodies in sediment from a pond where no mycelium or roots had existed before, indicated that vegetative growth was 14 cm/season (Paper V). This rate is similar to growth rates of other ectomycorrhizal fungi (Last & Fleming 1985)."

Und es wird zitiert, das dies auch für andere Mykorrhiza-Pilze ähnlich ist.
