Ciri dan struktur
Diagnosis: Mycosphaerangium quercinum is distinguished from the other species of the genus mainly by irregularly sinuous-knobby paraphysis tips encrusted by amorphous, olive to reddish brown plaques. Culture characteristics: Colonies on CMD 50-mm diam after 3 months at 22 °C, first hyaline, partly or entirely turning brownish or ochre, covered by floccose tufts or a dense white mat of aerial hyphae, with irregular wavy margin; reverse ochraceous with a caramel to dark brown centre. Conidia not observed in culture.
Habitat dan peran ekologis
Habitat: on dead corticated branches of Quercus spp., constantly associated with effete conidiomata of Coryneum spp. Distribution: apparently widely distributed in south-central and Southern Europe; confirmed from eastern Austria, Greece (Crete), Italy and Spain.
