Colonies and cardinal temperatures
Colony morphology on V8A and PDA with a rosaceous growth pattern. Minimum growth temperature 12°C, optimum 32°C, and maximum 36°C.
Conditions for growth and sporulation
Sporangia produced on V8-agar flooded with both distilled water and non-sterile soil extract. Hyphal swellings formed abundantly on V8A.
Asexual phase
Sporangia nonpapillate; persistent; ovoid to obpyriform (30–50 ×19–34 μm); showing internal (nested) and external proliferation; originated in unbranched sporangiophores. Hyphal swellings catenulate, elongated to globose and distorted shapes. Chlamydospores globose to obpyriform (20–48 μm), sometimes laterally attached.
Sexual phase
Sterile.
Hosts and distribution
Distribution: Asia (Vietnam)
Substrate: roots, fruit
Disease note: fruit rot, root rot
Host: Citrus grandis (Rutaceae)
