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, becoming greenish olivaceous, zonate. Reverse dull green, becoming blackish.

Two synanamorphs produced.

Libertella-like synanamorph:

Conidium-bearing regions distributed upon concentrically stromatized zones.

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

Conidiogenous cells terminal, cylindrical, smooth, 10-20 x 2-2.5 m, bearing slightly denticulate secession scars. Conidia produced holoblastically in sympodial sequence.

Conidia hyaline, dull amber in slimy masses, smooth, long cylindrical, slightly curved, 9.5-13 x 1-1.5 m, with flattened base indicating former point of attachment to conidiogenous cell.

Geniculosporium-like synanamorph:

Conidium-bearing regions sporadic.

Conidiophores dichotomously branched, hyaline, smooth-walled.

Conidiogenous cells terminal, long cylindrical, smooth, 20-60 x 2-3 m, bearing poroid secession scars. Conidia produced holoblastically in sympodial sequence.

Conidia hyaline, white in dry masses, smooth, ellipsoid, 4.5-5.5 x 2.5-3 m, with flattened base indicating former point of attachment to conidiogenous cell.
