Citation: Anthosphaera lafourcadii (Lecal 1967) Kleijne, 1991
Rank: Species
Basionym: Helladosphaera lafourcadii Lecal 1967
Synonyms:
Taxonomic discussion: Lecal (1967) refered to this species variously as Helladosphaera lafourcadiiHelladosphaera (Cyclohelladosphaera) lafourcadii and Cyclohelladosphaera lafourcadii

Distinguishing features: Like S. molischii HOL but BCs small, with irregular crystallites, CFC with low arch

Farinacci & Howe catalog pages: H. lafourcadii *


Morphology: Like A. fragaria, but BCs smaller (ca. 1 µm), and with less regular crystallites, ring of pores more consistently present, rim narrower; CFCs with low process (<1 µm), not extended into leaf.
