Summary
A new isolate of C. strobilus Parke and Manton has been investigated with light and electron microscopy to add significant details not previously studied. With the aid of a ciné record, to be described more fully elsewhere, some of the more important haptonema movements have been accurately timed. With the aid of improved technical methods of electron microscopy, new observations have been made on the haptonema base, and on the structure and mode of origin of the scales. The presence of 6 microtubules (instead of the more usual 7) in the very long haptonema of this species has been confirmed but the elaborate changes in tubule number and arrangement which take place in the haptonema base are shown to be essentially like those of other species. The morphology and arrangement of the two types of scale present on the cell are as previously described though information on several new and taxonomically valuable surface features have been added. The cup-shaped scales in particular are shown to be more different from those of other species now known in the genus than might previously have been recognised. This difference extends to the position of nascent scales within the Golgi system which is described in a preliminary way. Further discussion is deferred until some other new isolates representing related taxa have been described and named.
