Verticillium epiphytum Hansford, Proceedings of the Linnean Society, London 155: 41 (1943).

 

Morphology

Colonies rather fast-growing reaching 30–40 mm on PDA at 27–30ºC in 10 days, white, reverse from dirty white to yellowish cream to brown in centre of the colony. Phialides usually solitary on prostrate hyphae measuring 25–40 × 1.5–2.2 µm, forming globose to ellipsoidal conidial heads. Conidia falcate with blunt ends, some also nearly ellipsoidal, mostly 1-celled, rarely 2-celled, measuring 3.6–6(–8) × 1.5–2 µm. Chlamydospores scanty, terminal, generally 1-celled, globose to subglobose, to reniform or slightly constricted in the middle, hyaline, thick-walled with a rough chromophilic surface, measuring 6–7 µm. Crystals present or absent. Temperature optimum: 24–30ºC. Little growth at 33ºC. Two isolates of this taxon are preserved as IRAN 782 C (= CBS 113634) and IRAN 783 C (= CBS 113633) in the Iranian fungal culture collection at Iranian Research Institute of Plant Protection, Tehran, and the CBS, Utrecht, the Netherlands.

 

Distribution in Iran: This species was already reported from rust pustules mainly Hemileia vastatrix, the coffee rust. From Iran it was reported from Heterodera schachtii from Fars, Mashhad and Urmia during 2002-05.

 

Note: This species is unrelated to plant pathogenic Verticillium species and is characterized mainly by its simple conidiophores and production of scanty terminal solitary chlamydospores.
