Additional materials examined: USA, California, Palo Alto campus of Stanford University, on dead cankered branches of Eucalyptus globulus, 2001, G.C. Adams (MSC 380711, culture CBS 117005); ibid., Berkeley campus of University of California, on dead twigs of E. globulus, 8 Jun. 2001, G.C. Adams & H. Hallen (MSC 380709, culture CBS 116824). New Zealand, on stem and branches canker of Castanea sativa, unknown date, M. Braithwaite (culture CBS 101714).

Notes: Cytospora berkeleyi was described from dead cankered branches of Eucalyptus globulus in the USA (Adams et al. 2005), and clusters in a sister clade with C. diatrypelloidea. However, C. berkeleyi (CBS 117005) differs from C. diatrypelloidea (CBS 120062) in ITS (0/502), act (0/243), rpb2 (18/650), tef1-α (16/509) and tub2 (5/415) loci. Conidiomata of C. berkeleyi can have both a cytosporoid rosette and torsellioid features (Adams et al. 2005). Currently, this species has been found in the USA and New Zealand on Eucalyptus spp. and Castanea sativa.

Typus: USA, California, Palo Alto campus of Stanford University, on dead cankered branches of Eucalyptus globulus, 2001, G.C. Adams (holotype MSC 380710, ex-holotype culture CBS 116823).
