What does "f.a." stand for in the name of the "Wickerhamomyces menglaensis f.a." yeast species mentioned in this article https://ijs.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.003350 ?

"Forma asexualis" as explained in another paper

The authors favor the use of the expression forma asexualis (f.a.) in the description of anamorphic species of the genus Cystobasidium and this decision follows the current practice of reclassification of asexual yeast taxa (see e.g. Lachance 2012; Groenewald and Smith 2013; Daniel et al. 2013; Selbmann et al. 2014)

  • $\begingroup$ Nice answer. So does f.a mean the asexual strains of the same species? $\endgroup$

  • $\begingroup$ @WYSIWYG: yes. Before this change, the anamorph and teleomorph had to have different names, and were even in different genera... because they had different appearance. $\endgroup$

  • $\begingroup$ @WYSIWYG: actually the rules are more complicated for the existing names en.wikipedia.org/wiki/… i.e. they didn't force them out; that's why you mostly see "f.a." in combination with sp.nov (or more rarely comb.nov.) on a search. $\endgroup$

  • $\begingroup$ So what do sp. nov. and comb.nov. mean? Could you also add your comments to the answer as it would be useful to others? $\endgroup$
