Conidium ontogeny in Wallemia sebi (Fr.) v. Arx is analyzed and illustrated by time-lapse photomicrography. The nuclear configurations occurring during conidiogenesis are described and subsequent nuclear distribution reported. The conidia are considered to be meristem arthrospores of a unique type.

Conidium ontogeny in Torulomyces lagena Delitsch and Monocillium indicum Saksena, the type species of Torulotnyces and Monocillium respectively, is analyzed by time-lapse photomicrography. The nuclear configurations occurring during conidiogenesis are also described. Since their development and karyology are essentially identical and their morphology closely similar, we consider them congeneric. Monocillium indicum is accordingly transferred to Torulomyces.

Conidium ontogeny in Cladosporium herbarum (Pers.) Link ex S. F. Gray and Torula herbarum (Pers.) Link ex S. F. Gray is analyzed by time-lapse photomicrography. Both fungi are shown to produce conidia holoblastically in acropetal chains.

Time Lapse Photomicrography

The growth of sausage-shaped cells of the fission yeast, Schizosaccharomyces pombe (strain NCYC 132), was followed in the second or third cycle by time-lapse photomicrography. Experimental cells were harvested from glucose-limited (0.2% glucose EMM3) chemostat culture (dilution rate, 0.125/h) and were plated onto a slide with EMM3 agar (2% glucose). By observing their extension patterns, we found some rules of extension growth. Thus, (1) all sibs with walls newly formed in the previous cycle, whose progenitor cells grew at the old end (followed Mitchison's rule), grow at the old end (also follow Mitchison's rule). (2) Sibs with old walls whose progenitor cell followed Mitchison's rule behave in one of three ways: (i) growth at the old end (follow Mitchison's rule); (ii) growth at the new end (violate Mitchison's rule); or (iii) growth at both ends (bipolar). (3) Both sibs whose progenitor grew at both ends (bipolar) always grow at the old end (follow Mitchison's rule).

Conidium formation in Cladobotryum variospermum (Link) Hughes is analyzed by time-lapse photomicrography, and a developmental concept of the genus is proposed. We show how this concept can be reconstructed from observations of conidiogenous cells and conidia fixed at various ages. The morphology of conidiogenous cells and conidia of C. mycophilum (Oudem.) W. Gams and Hoozem., and C. dendroides (Bull. per Mérat) W. Gams and Hoozem. is interpreted in terms of development, and comparisons drawn with C. variospermum. We recommend that C. dendroides be excluded from Cladobotryum.
