Rhizina undulatu on stem and roots of 84-year-old Scots pine trees

Apothecia of Rhizina undulata Fr. were found on and around 84-year-old Scots pine trees in fire-free managed forest. The trees were weakened: crowns were strongly transparent, needles were yellowish or red MI part of the crown, the 1997 height increment of shoots decreased by about 60. One apothecium developed on the stem of tree. 7 cm above the ground level. The other 8 were associated with the roots. Three weeks after ascocarps had been removed 8 new ones were found. Some details referring to apothecia are given: distances from the root collar, dimensions, fresh weight, moisture and "index of undulativity" (Fw).
