Nomenclatural notes
Most authors give the epithet as "crouani" or "crouanii", but the genitive plural is required as it is intended to honour both of the Crouan brothers. "In Furnari et. al. (2003), Ballesteros (2010), Athanasiadis (2016) and AlgaeBase (Guiry & Guiry, 2017) this taxon is named H. crouaniorum, thinking that Agardh wanted to honour both of the Crouan brothers. However, in the absence of evidence from Agardh that both brothers were being honoured, agreeing with Woelkerling (pers. comm.) and what reported in INA (2017), we here prefer maintain the original orthography but corrected from 'crouani' to 'crouanii' in accord with Art. 60.12. of ICN (McNeill et al., 2012)." (Cormaci, Furnari & Alongi 2017: 89)." J. Agardh, however, only says ("Crouan!") and does not specify one brother or the other, and the two are always referred to collectively as the "brothers Crouan" or "frères crouan" and this is how most of their scientific works were authored, so AlgaeBase will continue to maintain the genitive plural in agreement with Athansaidis and others. At no time has anybody named a species for one brother as opposed to the other. - (9 May 2009) - M.D. Guiry

1852: 495 (Womersley 1994: 143); 1852: 496 (Irvine & Pueschel 1994: 238). - (8 Jun 2009) - Wendy Guiry

Habitat notes
Epilithic on pebbles mixed with maërl; depth range: 2-13 m (Peña & Bárbara 2010). Growing on pebbles associated with maerl beds; depth: 17 m (Pena & Bárbara, 2013). - (4 May 2010) - Wendy Guiry

General environment
This is a marine species.

Habitat
On stable rock and loose stones; forming indefinite, sometimes very extensive patches; margins rarely extending slightly over coralline algae, otherwise not epiphytic (Irvine & Pueschel 1994; 239).

Type information
Lectotype locality: Brest, France (Irvine & Pueschel 1994: 238). Lectotype: Herb. Alg. Agardh, LD 27613 (Irvine & Pueschel 1994: 238). Notes: Womersley (1994: 143) notes that the type material of Hildenbrandia crouanii was collected by Crouan.
