Holotype species: Petrohua bernabei G.W.Saunders
Original publication and holotype designation:Vis, M.L., Harper, J.T. & Saunders, G.W. (2008 '2007'). Large subunit rDNA and rbcL gene sequence data place Petrohua bernabei gen. et sp. nov. in the Batrachospermales (Rhodophyta), but do not provide further resolution among taxa in this order. Phycological Research 55: 103-112.
Taxonomic status: currently recognized as a distinct genus.
"Named for the beautiful waterfalls and river system, located in Chile's first national park, from which this plant was collected." - (3 Jan 2012) - M.D. Guiry
Description: Freshwater red alga; thallus terete lacking distinct nodes; immature thallus pseudoparenchymatous in construction, becoming filamentous; uniaxial, central filament with dense rhizoidal envelope.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.
Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
