Texture of aerial mycelium in culture

The categories and definitions of texture of aerial mycelium mat were used described by Stalpers (1978). One or more terms will be used for description of the texture.

1. Absent: mycelium only submerged. The surface of the agar may be even or chamois-like.
2. Downy: with fine, short, erect hyphae. The whole colony usually is transparent
3. Farinaceous: mealy, powdery.
4. Granular: covered with minute grains.
5. Cottony: rather long, single mycelia hyphae spreading in all directions.
6. Woolly: fairly long interwoven hyphae or groups of hyphae, somewhat matted, resembling woolen cloth.
7. Floccose: small hyphal tufts, standing out from the agar or from the aerial mycelium.
8. Plumose: mycelia tufts with short or long hyphae or groups or hyphae radiating from the central axis, often in fan-like arrangement.
9. Pellicle or subfelty: covered with thin, low, coherent mycelium.
10. Felty: cottony or wooly mycelium much has become matted or packed; emerging hyphae absent.
11. Velvety: a dense mat of erect, straight hyphae, usually short.
12. Crustose: hyphae forming a solid, hard crust, usually dark brown (many Hymenochaetaceae) but sometimes cream or white.
13. Lacunose: mycelial surface depressed or indented.
14. Zonate: with concentric bands or segments of different texture.
