He recognized the origin of the conidia within the conidiogenous cells as the character- istic feature of the genus and wrote: "the mechanism by which the conidia are formed in the interior of the conidiogenous cells ('Buchsen') is not precisely known, but is probably similar to endogenous spore formation in many other fungi. [...] In the urceolate type, the venter is obconical, with a narrow base corresponding to the width of the terminal cell of the conidiophore, and wider above. [...] The wall of the phialide may be of uniform thickness except for the distal part of the collarette where it becomes attenuated (e.g., Chalara ampullula [Figure SOD], C. fusidioides [Figure 30F] ) or it may be thickest at the base of the phialide, gradually becoming thinner towards the distal end of the collarette. [...] Cole and Kendrick (1969) investigated the development of the phialoconidia in a culture of Thielaviopsis paradoxa (conidial state of Ceratocystis paradoxa) in its early phase of growth and listed the following basic characters of conidium forma- tion: "1) During the early stage of differentiation, growth of the outer wall and conver- sion of the protoplast proceed simultaneously. [...] The point of initiation of the new growth is shown by an arrowhead, and the new conidiogenous locus by an arrow; initiation of a conidium at the newly proliferated apex is seen in the form of a bulbous swelling.
