21. The conidiophores and vegetative hyphae of " G . pannorum " are hyaline. 22. Mostly they develop a flat layer of relatively short conidiophores which then produce masses of spores. 23. The typical " Trichoderma " conidiophore , with paired branches assumes a pyramidal aspect. 24. On the lesions white mycelium can be found with conidiophores bearing either lanceolate or rounded condia. 25. Conidia develop at the tips and along the sides of branched, tree-like conidiophores . 26. Photograph of spores produced by the oak wilt fungus . ( a ) Endoconidia ( b ) Conidiophore 27. The conidiophores of " P . acicularis " are 30 ?m long, and unbranched. 28. Conidia are borne laterally and terminally on conidiophores , which usually occur in clusters of three to five. 29. Conidiophores project into the water and bear conidia, which are often sigmoid, branched or tetraradiate structures.30. This downy growth is the result of the production of conidia and conidiophores under the proper environmental conditions.
