Parasola conopilea

I emailed GenBank to let them know that they incorrectly had Parasola conopilea as the name when it should be Parasola conopilus (according to my memory and also Index Fungorum and got the following reply. Index Fungorum fixed it yesterday, so I fixed the name here too by editing the spelling.

From our taxonomist:

The name is now corrected at Index Fungorum as Parasola conopilea, and we made the same update. Some text to explain this rather messy update via Shaun Pennycook:

The protologue description is under Agaricus conocephalus (Syst, Mycol. 1: 304. 1821) - then on p. 504, Fries says the “A. conocephalus” sensu Albertini & Schweinitz and sensu Fries is designated as Agaricus conopilus Fr., because it differs from the original Bulliard A. conocephalus.

Although pilus is a Latin noun, the epithet conopilus is a masculine adjectival compound epithet, with feminine form conopila and neuter form conopilum. However, it translates as “conical-haired”, which as far as I am aware is NOT a character of Agaricus conopilus. On the other hand, conopileus is an obvious character of this taxon (and it is cognate with the “original” epithet conocephalus).

Fries (1838, p. 231) listed it as Agaricus (Psathyra) conopilus under “section” Conopili; but Fries (1874, p. 304) changed (corrected!) the epithet to Agaricus (Psathyra) conopileus, under “section” Conopilei {see http://bibdigital.rjb.csic.es/... } For my money, the original orthography “conopilus” is an obvious orthographic error (which Fries was somewhat prone to), and the correction to conopileus /—a /—um is permitted by ICN Art. 60.1.

Karsten’s Psathya conopilus is a correctable error, typical of several of the authors of the period when Agaricus names were being recombined into new genera (Quélet did this numerous times in the first of his Champignons du Jura papers) - it is as if the masculine Agaricus epithet was so ingrained in their minds that they forgot to change it to feminine to agree with gender of the new genus. Quélet (1872, p. 148) had Psathyra conopilus, but subsequently corrected this (Enchiridion 1886, p. 116; Flore Mycol. 1888, p. 59) to Drosophila (Psathyra) conopilea.
