Identification

Stromata

70-300 μm in diameter
Bear prominent, dark, septate spines (setae) up to 100 μm long.

Conidia

Developing at the base of the spines
Hyaline to pale yellow, unicellular, sickle-shaped, falcate to fusiform, tapered toward both ends
3-5 x 19-29 μm.

Phialides

Unicellular, hylanine and cylindrical,
4-8 x 8-20 μm.

Growth on PDA

Gray and feltlike
Conidia and appressoria are numerous when culture are well aerated, and sclerotia sometimes occur.
Appressoria are diagnostic: they are tawny brown, irregular-shaped in edge, prominent, and terminal on thickened hyphae.
