Sched. Crit. Lich. Suec. 8-9: 20 (1826).

Basionym: Capitularia symphycarpia Flörke, Beitr. Naturk. 2: 281 (1810).

Type locality: Germany, Thuringia, Nordhausen, Alter Stolberg, 1920, H. Sandstede & K. Wein, Sandstede: Cladon. Exs. 689 (UPS - neotype; H - isoneotype). Neotypification by Ahti (1993: 99).

Note: There are contradicting spellings: Cladonia symphycarpa (Ach.) Fr., without the "i" and deviating authors in John (1990:126), C. symphycarpa (Flörke) Fr. in Ahti (1993: 99), but C. symphycarpia (Flörke) Fr. in Wirth et al. (2011: 35), and Wirth et al. (2013: 412).
"The suffix meaning “—fruit”, “—fruited” is –carpus/-a/-um, and I have not found anything to suggest that it should have an “—i—“ inserted before the ending. The Zahlbruckner entry lists several variants (with the orthography “symphi—“) but all except one of them end in “—carpa”. The Flörke basionym was definitely published as Capitularia symphycarpa (with a reference back to Baeomyces symphycarpus Ach.). If Flörke is accepted as the basionym author, I think the orthography must be retained as “symphycarpa”. - Shaun Pennycook 11 June 2018.
