CULTURES AND ANAMORPH

Colonies on 2% Difco oatmeal agar incubated at 20C and 12 h of fluorescent light covering Petri dish in 4-5 wk, at first whitish, velvety, with diffuse margins, soon showing alternating bright yellow and greenish olivaceous concentric zones. Reverse uncolored.

Two synanamorphs produced.

Libertella-like synanamorph:

Conidium-bearing regions distributed within or upon irregular stromatized areas which are dull green on the surface.

Conidiophores di- or trichotomously branched, with hyaline to pale brown stipes, smooth-walled, arranged in dense palisades.

Conidiogenous cells terminal, cylindrical, smooth, 20-30 x 1.5-2 m, bearing slightly denticulate secession scars. Conidia produced holoblastically in sympodial sequence.

Conidia hyaline, dull green in slimy masses, smooth, long cylindrical, slightly curved, 10-18 x 1-2 m, with flattened base indicating former point of attachment to conidiogenous cell.

Geniculosporium-like synanamorph:

Conidium-bearing regions usually distributed upon the stromatized areas.

Conidiophores unbranched or branched, hyaline, smooth-walled.

Conidiogenous cells terminal, long cylindrical, smooth, 15-30 x 2 m, bearing poroid secession scars. Conidia produced holoblastically in sympodial sequence.

Conidia hyaline, white in dry masses, smooth, ellipsoid to clavate, 4.5-11.5 x 1.5-3 m, with flattened base indicating former point of attachment to conidiogenous cell.
