Vulcanochloris Vancurová, Peksa, Nemcová & Skaloud, 2015

Holotype species: Vulcanochloris canariensis Vancurová, Peksa, Nemcová & Skaloud

Original publication and holotype designation: Vancurova, L., Peksa, O., Nemcová, Y. & Skaloud, P. (2015). Vulcanochloris (Trebouxiales, Trebouxiophyceae), a new genus of lichen photobiont from La Palma, Canary Islands, Spain. Phytotaxa 291: 118-132.

Description: Vegetative cells spherical, rarely oval or oviform. Cell wall thin, seldom a flat local thickening of the cell wall can be observed. Rarely, the cell wall is slightly thickened along its entire surface. Cells contain a single asteroid chloroplast, with a distinct pyrenoid in its centre. The pyrenoid often contains one to several spherical incisions. Prior to aplano- and zoosporogenesis, the chloroplast flattens and assumes a parietal position. Asexual reproduction by 16–128 aplanospores or 64–128 zoospores. Zoospores naked, with two apical flagella and a simple basal chloroplast; stigma not observed. Mature aplanospores and zoospores liberated by rupturing of the mother cell wall. Lichen photobiont, so far found only in thalli of Stereocaulon vesuvianum. Morphologically similar to Asterochloris, from which it differs by the presence of spherical incisions in the pyrenoid matrix.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
