Conidial state of Nectria haematococca Berk, & Br.
   
 
 
 
 
　Description： On PDA, growth is rapid, often with aerial mycelium sparse to dense, white to pale buff. Colonies reach 2.8-3.7 cm diameter for 4 days at 24℃. The surface is covered with confluent sporodochia that give the appearance of pionnotes with cream, yellow, buff, green or dark bluish green color. Microconidia develop abundantly on WA in false heads, elliptical, reniform or obovate, 0-septate, 3.8–16.8 × 2.5–5.0 μm, formed from monophialides of hyaline, elongated branched or unbranched conidiophores, 46-175 μm long. Macroconidia develop from monophialides of short branched or unbranched conidiophores, hyaline, cylindric, slight curved with a beak apical cell and foot-shaped basal cell, mostly 4-7 septate, 40–67 × 3.8–5.0 μm. Chlamydospores formed in both hyphae and conidia, terminal or intercalary, thick-walled, solitary, in pairs or in chains, 5-10 μm diameter. Nectria haematococca Berk. & Br. is homothallic or heterothallic and the teleomorph is obtained by pairing compatible monoconidial isolates on Sach’s agar media or PDA. Perithecia are globose to pyriform with pale orange to ochre color and appear gelatinous with rough warted outer wall, measuring 250-380 μm. The asci are cylindrical or clavate, 57.5-92.5 × 10-12.5 μm. The ascospores are ellipsoid to clavate, 8.8-13.8 × 5.0-7.5 μm, one septate, constricted at the central septum.

　Note： In this island, two formae speciales of F. solani have been found as follows: (1) F. solani (Mart.)Sacc. f. sp. cucurbitae Snyder & Hansen—the causal agent of cucumber root rot. (2) F. solani (Mart.) Sacc. f. sp. pisi (Jones) Snyder & Hansen—the causal agent of pea root rot.
