Light microscopy of <i>Escovopsis</i> ex type cultures. (A–B) <i>Escovopsis weberi</i> ex type culture, ATCC 64542:

<p>Spore chain still attached to phialide on cylindrical vesicle, showing the relatively early development of the pigmented outer spore wall or sheath (<b>A</b>); Close-up of another conidium with prominent outer sheath (<b>B</b>). Most conidia are older and detached before the pigmentation and separation of the outer wall or sheath become obvious. (<b>C</b>) <b><i>Escovopsis aspergilloides</i></b><b> ex type culture, CBS 423.93:</b> Detached spore chain in various stages of maturation, showing pigmentation and prominent outer walls. Arrows indicate the outer caps. All scale bars = 5 µm.
