Original description
On Sabouraud dextrose agar, Lichtheimia hongkongensis grows rapidly as cottony colonies and attains a diameter of 64 to 73 mm after incubation at 37°C for 48 h. Microscopic examination after lactophenol cotton blue staining shows non-septate broad hyphae. The sporangiophores are highly branched. The diameters of main sporangiophores are 8-10 µm and those of the side branches are 3-5 µm. The sporangiophores terminate in sporangia or the columellar remnants. Most of the side branches are characteristically circinate, but sometimes they are arranged in umbel, usually at the terminals. The circinate sporangiophores are also evident when young colonies are directly observed under the microscope using a 10× objective. Rhizoids are not observed. The sporangia (25-35 µm) are hyaline, multispored and pyriform in shape. The columella (15-21 µm) is dome-shaped with a prominent flask-shaped apophysis. Hyaline sporangiospores (2-3 × 3-4 µm) are formed inside sporangia. Most of them are smooth and globose to subglobose in shape, but are sometimes ellipsoidal and polygonal. Characteristically, abundant pleomorphic giant cells with finger-like projections, usually submerged in agar, are observed. |
