Host Tree

The anamorphic fungus Cryptostroma corticale was first isolated from sugar maple (Acer saccharum Marshall) logs in 1889 (Ellis & Everhart, 1889) in Canada. Afterwards, the following record of the fungus was already in Europe on sycamore (A. pseudoplatanus), hickories (Carya spp.) and basswoods (Tilia spp.) (Gregory, Peace and Waller, 1949; Gregory and Waller, 1951) as well as in North America on maple (Acer sp.), (Gregory and Waller, 1951). Further notifications of SBD were associated with other species of maple such as field maple (A. campestre L.) (Moreau and Moreau, 1954), Norway maple (A. platanoides L.) (Moreau and Moreau, 1954; Bencheva, 2014), and ash-leaved maple (A. negundo L.) (Moreau and Moreau, 1954; Young, 1978), red maple (A. rubrum) (Washington State Department, 2021) and more recently to bigleaf maple (A. macrophyllum) (Brooks et al., 2023) and other Acer spp. (Brooks et al., 2022). Other tree species have been also identified as potential tree hosts but might be affected to a lesser extent such as Aesculus hippocastanum L. (Young, 1978; Brooks et al., 2022; Brenken et al., 2024), Betula spp. (Cochard et al., 2015; Brooks et al., 2022) or Fraxinus excelsior (Langer et al., 2023).
