Cheiromoniliophora elegans Tzean & Chen, Mycol. Res. 94: 424-427. 1990.

 Description: Colonies effuse, centre farinose, brownish grey, margin greyish yellow to white; reverse centre greyish red, middle brownish yellow, margin light yellow. Mycelium superficial, composed of repent, branched, septate, hyaline or subhyaline, smooth or verrucose hyphae, 0.8-8.4 μm wide. Conidiophores semi-macronematous, macronematous, simple or irregu-larly branched, septate, rarely slightly constricted at septa, smooth or verrucose, 10.2-56.0 μm high, 3.2-6.4 μm wide. Conidiogenous cells discrete, catenulate, proximally clavate, pyriform to obovoid, distally spherical, subspherical, mono-, or polyblastic, smooth or occasionally verrucose, hyaline to subhyaline, 4.7-24.2 × 4.2-13.6 μm. New chain of conidiogenous cells may regenerate from pre-existing conidiogenous cells. Conidia holoblastic, acrogenous or pleurogenous, cheiroid, in one plane, composed of 2-3 arms, arising from a more or less triangular basal cell. Arm multiseptate, slightly constricted at septa, consisting of 1-5 cells, brown or dark brown, smooth, thick-walled, up to 1.6 μm, 11.2-27.2 × 9.5-16.8 μm. Conidia are produced from conidiogenous cells laterally or apically, at one or two loci and are at first spherical or subspherical in shape. Later they develop a transverse septum, and then become further divided by an oblique or longitudinal septum to become multicellular and more or less U-shaped. The conidia mature in situ, in one plane and become obovoid, consisting of what appear as 2-3 compressed arms, each arm composed of 1-5 cells, arising from a triangular basal cell.

 Note: The gross morphology and morphogenesis of the cheiroid conidia of Cheiromoniliophora elegans are close to those of Pseudodictyosporium wauense, but differ in several features. The length is shorter and branching of the conidiophores is sparser in C. elegans than in P. wauense. The ovate basal cell in the conidiophore in P. wauense is not present in C. elegans. The conidiogenous cells bear a solitary, terminal conidium, whereas in C. elegans, the conidiogenous cells are of a distinct shape, mostly spherical, subspherical or monilioid, and are markedly distinct from the tubular conidiophores. Each conidiogenous cell is fertile, either monoblastic or polyblastic, producing conidia apically or laterally (cf. Figs 10-12). Sometimes, a long chain of conidiogenous cells can be regenerated from preexisting conidiogenous cells.
