Pseudocercospora norchiensis Crous View in CoL , Fungal Diversity 26: 172. 2007 ( Fig. 5 View FIGURE 5 )

Type:— ITALY. Viterbo, Norchia, on Eucalyptus sp. (Myrtaceae) , April 2005, W. Gams (holotype CBS-H 19841, culture ex-type CBS 120738 = CPC 13049) ( Crous et al. 2007).

Description in planta:— Leaf spots amphigenous, subcircular to circular, 2–7 mm diam., with brown centre and dark purple margins. Mycelium internal. Caespituli epiphyllous. Stromata well-developed, substomatal to intraepidermal, semi-immersed to superficial, 25–60 μm diam. Conidiophores arranged in moderately dense fascicles, arising from stromata, through stomata or erumpent through the cuticle, brown, smooth, 1–6-septate, unbranched, straight to curved, subcylindrical, regular in wide, (15–)50–70 × 3–4(–5) μm. Conidiogenous cells terminal, brown, smooth, proliferating sympodially, (8–)10–16(–22) × 3–4(–5) μm, loci neither thickened nor darkened. Conidia solitary, pale brown, subcylindrical to obclavate, apex subobtuse to subacute, base obconically truncate, straight to gently curved, 1–8-septate, (18–)42–55(–85) × 3–4.5 μm; hila neither thickened nor darkened or refractive, 1–2.5 μm diam.

Habitat/Distribution:— Known to inhabit Eucalyptus sp. and Rubus sp. , in Iran, Italy, New Zealand and Uruguay ( Crous et al. 2007, 2013 a, Perez et al. 2013).

Other material examined:— IRAN. Guilan Province: Talesh, Dulbin, on Rubus sp. (Rosaceae) , August 2011, M. Bakhshi (CCTU 1009). Dulbin, on Rubus sp. , October 2011, M. Bakhshi (CCTU 1032). Guilan Province: Rezvanshahr, Paresar, on Rubus sp. , September 2011, M. Bakhshi (CCTU 1019).

Notes:— In the ACT and TEF1-α phylogeny, isolates of P. norchiensis cluster in a distinct clade, sister to P. nogalesii . In combined gene tree, this species resides in a distinct well-supported clade sister to P. nogalesii . This species represents new record for Iran (Asia).
