Holotype species: Phyllobium dimorphum Klebs

Original publication and holotype designation: Klebs, G. (1884). Beitr├Ąge zur Kenntnis niederer Algenformen. Botanische Zeitung 39(17): 265-272.

Taxonomic status: currently recognized as a distinct genus.

Description: Thalli unicellular, endophytic, growing in dead (rarely living) leaves of some vascular plants or bryophytes. Cells solitary or in groups, irregularly globose, ellipsoidal, prolonged ovoid or club-shaped, usually with single cell wall protrusions forming elongated, sometimes branched, rhizoid-like projections. Chloroplast as parietal plates or radially arranged strands. Asexual reproduction unknown. Sexual reproduction anisogamous; after fusion, microgametes loose flagella, resulting in biflagellate zygote. After short motile period zygospore settles on host plant and forms tubular projection that penetrates into host. Vegetative cells form more or less globose or ellipsoidal resting cells containing considerable starch and red oil droplets. On germination resting cells release gametes. Phyllobium endophytic, found in leaves of some vascular plants or bryophytes (e.g., Lysimachia, Poaceae, Cyperaceae, Sphagnum); reported from Europe and North America. Genus of uncertain status, recent observations lacking.

Numbers of names and species: There are 3 species names in the database at present, of which 3 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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