| Abstract: | On Grovesiella abieticola (Zell. and Goodd.) Morelet and Gremmen . Grovesiella abieticola (=Scleroderris abieticola) is an inoperculate Discomycete (related but distinct from the genera Godronia Moug. et Lév., Durandiella Seaver and Pragmopora Massal.), occurring in Europe and North America on species of the genus Abies Miller. The fungus is associated with branch cankers and dieback of twigs, although its pathogenicity has not been proved so far. After a three-weeks period of growth in vitro the fungus develops plurilocular pycnidia oozing bacilliform, unicellular microconidia. It demonstrates an optimal growth at 18–20°C. |
