Armillaria Root Rot in Eucalypt Forests: Aggravated Endemic Disease!

Species of the woody root rot fungus Armillaria are indigenous in cool temperate rain forest, mixed forest, and wet and dry sclerophyll eucalypt forests in Australia. Four species have been described or identified from southeastern Australia: A. luteobubalina Watling and Kile, A. fumosa Kile and Watling, A. hinnulea Kile and Watling, and A. novae-zelandiae (Stevenson) Boesewinkel.

Root Rot of Teak 2. Further Field Observations with New Records of Armillaria Mellea

The root rot fungus Armillaria mellea introduced into South Africa by early Dutch settlers.

Dead and dying oak (Quercus) and numerous other woody ornamental trees and shrubs showing signs and symptoms of Armillaria root rot were identified in the Company Gardens, Cape Town, South Africa, which were established in the mid-1600s by the Dutch East Indies Trading Company. Nineteen isolates from dying trees or from mushrooms were collected and analysed to identify and characterize the Armi...

Pythium root rot associated with cool-season dieback of turfgrass in Ontario and Quebec

Pythium species were isolated from diseased samples of creeping bentgrass and annual bluegrass. Among fourteen isolates from decayed roots and crowns, seven were P. graminicola, five were P. torulosum and two were P. ultimum. These species were identified by comparison of cultural and morphological characteristics to literature and reference isolates. In a tissue culture plate assay for quantif...
