Ophiostoma pseudobicolor

Ciri dan struktur

Diagnosis: Ophiostoma pseudobicolor is the closest phylogenetic relative to O. bicolor. Morphologically, these two species differ by the size of their perithecia, with globose bases ranging from (308–) 350–480 (− 536) μm in O. pseudobicolor vs. 175–350 (− 365) μm in O. bicolor (Upadhyay 1981). The necks of O. pseudobicolor are more robust than those of O. bicolor, especially at the apex [viz. (43–) 49–68 (− 77) μm vs. 15–42 (− 50) μm]. Description: Sexual morph perithecial. Perithecia developing on 2% MEA at 25 °C after 15 d from superficial or embedded mycelium, superficial or partly embedded in the agar medium, with the base globose, subhyaline to yellow orange, (309–) 350–480 (− 536) μm diam., extending into a filiform neck; bases globose, prolonged by a cylindrical, straight or slightly curved, occasionally twinning neck, black (663–) 754–1100 (1358) μm long, (33–) 55–77 (− 79) μm wide at the base down to (43–) 49–68 (− 77) μm wide at the apex, composed of densely packed septate hyphae with a parallel orientation. Ostiolar hyphae absent. Ascospores hyaline, elliptical to oblong with obtuse ends in side and face view, circular in pole view, surrounded by a thick, hyaline gelatinous sheath appearing ossiform in side and face views, quadrangular with flanged corners in the end view, aseptate, (5.5–) 6–6.5 (− 7) × (3–) 3.5–4 (− 4.5) μm, included sheath.
