Feature of microscopy:
hyphae are asepta, micellium have
branches, conidiophores upright, prolong,
but have branchless. The edge swells and
produces vesicle. On the whole vesicle
surface micellium are covered, forming
phyalide. Conidia are formed subsequently
in the phyalide. Conidia are spericle,
hyaline, and 1 cell sterigmata.
