A Grammatical Dictionary of Botanical Latin

 
Protothallus,-i (s.m.II), abl. sg. protothallo: protothallus, “the first part formed by Lichens after germination is over” (Lindley); “= hypothallus, the first-formed stratum of a Lichen” (Jackson); “the first-formed stratum of a lichen; same as ‘hypothallus’ for that group” (S&D) [> Gk. proto, ‘first’ + thallus, a shoot]; see hypothallus,-i (s.m.II); see prothallus.

NOTE: the following examples from moss text indicate the protothallus may be essentially synonymous with protonema, q.v.;

- [Schistostega osmundacea; moss] protothallus plantae germinantis (Catoptridium smaragdinum) memorabiliter lucens (C. Mueller), the protothallus of the germinating plant (Catoptridium smaragdinum) remarkably shining.

- [Ephemerum serratum; moss] basi filis protothalli instructum (C. Mueller), at the base provided with the threads [i.e. filaments] of the protothallus.

- [moss] gregariae humillimae acaules in protothallo viridi positae terrestres (C. Mueller), gregarious, very small in stature [i.e. inconspicuous], stemless, situated on a green protothallus, growing on soil.

- [Discheliaceae; moss] gregariae humillimae acaules in protothallo viridi positae terrestres (C. Muell.), gregarious [i.e. colonial] very low, stemless, terrestrial, situated on a green protothallus.

 

A work in progress, presently with preliminary A through R, and S, and with S (in part) through Z essentially completed.
