[edit] Identification
Stromata
- 70-300 μm in diameter
- Bear prominent, dark, septate spines (setae) up to 100 μm long.
Condia
- 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
