Several perennial species of rhizomatous herbaceous ferns are cultivated as ornamental foliage plants. During late summer 1999, in a garden at the foot of Mount Etna, eastern Sicily (Italy), we noted a fern hedge showing patches of withered or stunted plants. The fern was identified as Cyrtomium falcatum (L.f.) C. Presl. (=Polystichum falcatum (L.f.) Diels), a house holly fern or Japanese holly fern, which is an ornamental fern native to East and South Asia. Other woody plants in the immediate vicinity had died over the last few years, including apricot and cedar trees whose stumps had not been removed. A close examination of uprooted ferns revealed the presence of creamy white fan-shaped …
First Report of Armillaria Butt Rot Caused by Armillaria mellea on Phoenix canariensis in Italy.
2007
During 2006, in a garden in the Mount Etna Piedmont, eastern Sicily (Italy), a 40-year-old specimen of Canary Island date palm (Phoenix canariensis hort. ex Chabaud) with a trunk circumference at breast height of 220 cm showed a rotted lesion with a viscous, brown ooze at the stem base and root initials. The lesion extended to approximately one-third of the trunk circumference. Trunk excavation exposed a wet rot of internal tissues, a cream-colored mycelial mat, and a mushroom-like smell. Although the rot spread inward (approximately 25 cm deep) with decay of nonlignified ground tissues and blackening of wood fibers, the palm did not show symptoms on the canopy. Conversely, ferns, apricot,…
