1915 Mycologia 7 136 Each conidiophore typically produces a crown or verticel of metulae, or fertile branches.
1930 C. Thom Penicillia i. 6 Forms are found in which the sterigmata are supported by a second verticil of well differentiated cells..which have been called branches, basidia, secondary sterigmata, and finally metulae by Westling in 1913.
1947 C. E. Skinner et al. Henrici's Molds, Yeasts, & Actinomycetes (ed. 2) v. 103 The genus Penicillium is characterized by the production of conidia from sterigmata.., which are produced in clusters or whorls..from short branches (metulae) given off..from the tip of the conidiophore.
1961 G. C. Ainsworth Ainsworth & Bisby's Dict. Fungi (ed. 5) 246 Metula (e.g. of Penicillium and Aspergillus), a sporophore branch having phialides.
1978 Arch. Microbiol. 116 119 Young conidiophores, metulae (of the Penicillia), vesicles (of the Aspergilli), sterigmata and young spores, were also labelled.
1999 Molecular & Gen. Genetics 260 510 We have isolated the hymA mutant, in which conidiophore development is affected at the metula stage.
