On PDA, growth is slow, with cream or yellow, globose or confluent sporodochia formed in abundant, white, powdery, aerial mycelium. Colonies reach 2.5-3.0 cm diameter for 4 days at 24℃. Microconidia formed in long chains and in false heads are hyaline, oval and with a small flattened basal papilla, 0-1 septate, 7.5-12.5 × 3.5-5.0 μm. Macroconidia are very large, thick-walled, cylindrical, slightly curved, with a beaked apical cell and distinct pedicellate foot cell, mostly 6-9 septate, 71.3-97.5 × 7.2-7.5 μm. Chlamydospores are absent. Nectria rigidiuscula (Berk. & Br.) Sacc. is heterothallic or homothallic and the teleomorph is obtained by pairing compatible monoconidial isolates on Sach’s agar media or PDA. | |||
