Description: Plants uniseriate filamentous, largely endophytic in other algae, only the reproductive structures emergent from the host. Thallus weakly heterotrichous, with a differentiation of long prostrate and short "erect" filaments. Cells with a centrally located or laterally displaced stellate chloroplast with a central pyrenoid. Plants monoecious. Spermatangia terminal on the cells of corymbose clusters. Carpogonia sessile or pedicellate, distinct carpogonial filament absent. Carpogonium dividing longitudinally after fertilization, producing short horizontal gonimoblasts. Carposporophyte small, globose, with terminal carposporangia; sterile involucre absent. Monosporangia produced in addition to sexual reproductive structures, terminal on the "erect" filaments. Tetrasporangia and complete life history unknown. The type species an endophyte in Liagora and other members of the Helminthocladiaceae, both in the (sub)tropical western Pacific and in the Caribbean. Some (semi-)endophytic species presently included in Acrochaetium may in actual fact be more closely related to Liagorophila, e. g. A. brebneri (Batters) Hamel (syn.: A. immersum (Rosenvinge) Hamel).

Verification of Data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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