FUNGI OF OCULAR IMPORTANCE
The majority of the filamentous fungi isolated in the ocular microbiology laboratory belong to the Subclass Hypomycetes. The Order Moniliales of the Subclass Hypomycetes is divided into two families, the Moniliaceae and the Dematiaceae. Members of the Family Monilialceae have hyaline hyphae, conidiophores, and the majority have hyaline conidia. Members of the Family Dematiaceae have hyphae, conidiophores, and conidia that are pigmented. They are often referred to as dematiaceous hyphomycetes or dematiaceous fungi.
HYPHOMYCETES (HYALINE FUNGI)
ACREMONIUM SPECIES (CEPHALOSPORIUM SPECIES).
Growth matures within 2 to 6 days. Colonies are white, pink, or gray. Reverse is colorless, pale yellow, or pinkish. Texture is moist, spreading, becoming woolly with age. Microscopic findings include slender, delicate septated hyphae. Conidiophores are simple and erect with one-celled, occasionally two-celled, conidia arranged in clusters at the tips.
