Genome assembly of two California isolates of Seiridium cardinale (BM-138-000494 and BM-138-000479)

Seiridium cupressi (Nattrass, C. Booth & B. Sutton) Bon- thond, Sand.-Den. & Crous, is an Ascomycete fungus belonging to the family Sporocadaceae. Together with other six Seiridium species, including S. cardinale (W. Wagener) B. Sutton & I.A.S. Gibson and S. unicorne (Cooke & Ellis) B. Sutton among them, S. cupressi is one of the causal agents of the Cypress Canker Disease pandemic (CCD) (Graniti 1998; Danti et al. 2013; Bonthond et al. 2018). The phytotoxic activity of S. cupressi has been studied, includ- ing the toxins that this species is able to produce, such as Cyclopaldic acid (Graniti et al. 1992; Sparapano & Evidente 1995) and Seiricuprolide (Ballio et al. 1988; Bartolucci et al. 1992). Nevertheless, genomic-level information that may enable us to better understand gene expression and the pathogenicity of CCD causal agents is still missing. In this study, two isolates of S. cupressi, BM-138–000515 and BM-138–000234, were retrieved from the Italian National Research Council of Sesto Fiorentino (Florence, Italy) CNR- IPSP-FTFC mycological collection (https://biomemory.cnr. it/collections/CNR-IPSP-FTFC/). These two isolates have been cultured from symptomatic tissue of Cupressus sem- pervirens located in Kos island (Grece) in 1984.
