massive infection
some sporangia
infected hyphae and conidiophore
Berberis aquifolium, Nieuwendam, parasitising on Erysiphe berberidis
conidia are discharged
the infestation was so strong that also here the mycelium had got a brownish hue.

septate hyphae develop inside the hyphae, conidiophores and conidia of the host fungus. Here also more of less fusiform pycnidia are formed that contain elliptic, c.4 µm long conidia. In exceptional cases conidia are formed also in seemingly mature cleistothecia.
host species include
Erysiphe alphitoides, berberidis, friesei, heraclei, necator; Golovinomyces cynoglossi, sordidus; Neoerysiphe galeopsidis; Podosphaera fusca, macrospora.
synonyms
