Enlargement of orifices. D. Colony surface, showing numerous frontal avicularia; ooecia also abundant. E. Suboral and frontal avicularia; note that avicularia can have rounded (arrows) or more acute (white arrowheads) proximal end of rostrum; also note V-shaped crossbar elements (black arrowheads) of avicularia.
