The colonies of Pestalotiopsis on PDA were whitish with crenated edges and aerial mycelium
The colonies showed smooth borders and little aerial mycelium
to slightly cottony mycelium in the three culture media.
The morphology of the fungal clones that include peculiarities of the advancing (marginal) zone, aerial mycelium
, colony color, and possible changes in the reverse colony surface were observed and recorded.
The isolate produced cultures with a petaloid appearance, dense and cotton-like aerial mycelium
White aerial mycelium
was found on tryptone yeast extract agar medium, glycerol asparagine agar medium and peptone yeast extract iron agar medium whereas the aerial mycelium
was brownish white on starch nitrate agar medium, inorganic salt starch agar medium and tyrosine agar medium and pink on yeast extract-malt extract-agar.
Colonies were cottony in texture with fine white aerial mycelium
Fungal colony was convex and pale greenish grey medium aerial mycelium
After 7 days, characteristic house mouse gray silky colonies with aerial mycelium
grew on both these medias.
Dense or loose rosette spreading aerial mycelium
with no pattern (A), slender coenocytic hyphae (B), with rounded or angular hyphal swellings, often in chains (catenulate) and delimited by septa (C).
The most frequently encountered actinomycetes with pink, gray, dark Drown color of aerial mycelium
Streptomyces forms a genus of actinomyces, this organism has extensively branching secondary or aerial mycelium
, and primary or substrate mycelium.
Authors report white aerial mycelium
, which is a characteristic manifestation of this disease and the pathogenic fungus Saprolegnia.
