Apiosporaceae, Xylariales, Sordariomycetes
DESCRIPTION
FSexual form: branched, septate, brown to dark brown mycelium.
Sporodochial conidiomata, sporodochial, punctate, scattered or confluent, black, (150-)169-203(-220) µm long × (70-)76-88(-100) µm wide.
Conidiophore mother cells on stroma surface, lageniform to ellipsoidal or doliform, hyaline to brown, measuring (12-)13.4-14.2(-15) × (4-)6-7.2(-8) µm. Conidiophores arising from the conidiophore mother cell, basal-axial, cylindrical, straight to flexuous, hyaline, except for thin, smooth transverse septa, measuring (19-)28-44(-55) × 3-3.6(-4) µm. Conidiogenous cells monoblastic, integrated, terminal and intercalary, cylindrical. Conidia brown, solitary; frontal view: globose to ovate to ellipsoidal, with pale germinal cleft, (11-)12.1-13.5(-18) µm in diameter; lateral view: lenticular, (8-)8.4-9.2(-10) µm in diameter. Sterile cells observed only in culture, brown, granular, irregularly lobed, (19-)25-31(-35) × (6-)8.15-8.45(-12) µm in diameter. Culture characteristics: Colonies on MEA medium white and cottony, with grey patches, grey reverse. Reaches 80-90 mm diameter in 14 days at room temperature, sporulating after 5 weeks.
A: Cologne in cultivation, B–E Conidiophore mother cell with septate conidiophore giving rise to conidia, C irregularly shaped lobulated sterile cell, F Conidia in frontal and lateral view, G Conidiophore stem cell with irregular conidia in culture.
Conidiophore mother cell with septate conidiophore giving rise to conidia (B–E). Scale A 100 µm, B-G 5 µm.
