| 21. | Heterothallic fertilization occurs once two haploid mycelia ( homokaryons ) of different mating types have made contact.
|
| 22. | When environmental conditions are suitable, the chlamydospores germinate, producing mycelia ( or hyphae ) and sporangia.
|
| 23. | Towards the end of the cereal host's growing season, the mycelia produce structures called telia.
|
| 24. | Thin hyphae make up the mycelia, measuring from 1 to 2 micrometers ( ?m ) in diameter.
|
| 25. | It produces branching substrate mycelia and spherical spore vesicles on aerial hyphae that contain non-motile spores.
|
| 26. | The base of the fruit bodies are attached to the substrate by rhizomorphs ( thickened cords of mycelia ).
|
| 27. | It also produces a chitinase A able to produce protoplasts from " Schizophyllum commune " cultured mycelia.
|
| 28. | The optimum temperature for the growth of mycelia is, while the optimum for the growth of primordia is.
|
| 29. | The spores then germinate and the mycelia, or vegetative structure of the fungus, grows into the wood.
|
| 30. | It has been suggested the electrical stimulus of a lightning bolt striking mycelia in logs accelerates the production of mushrooms.
