Gliocladium species have a worldwide distribution and are commonly isolated from a
wide range of plant debris and soil.
RG-1 organism.
Gliocladium Corda
Morphological Description: The genus Gliocladium is often described as a
counterpart of Penicillium with slimy conidia. Colonies are fast growing, suede-like to
downy in texture, white at first, sometimes pink to salmon, becoming pale to dark green
with sporulation. The most characteristic feature of the genus is the distinctive erect,
often densely penicillate conidiophores with phialides which bear slimy, one-celled
hyaline to green, smooth-walled conidia in heads or columns. Although, penicillate
conidiophores are always present, Gliocladium species may also produce verticillate
branching conidiophores which can be confused with Verticillium or Trichoderma.
Key Features: Hyphomycete producing distinctive erect penicillate conidiophores with
phialides bearing clusters of single-celled conidia.
