SPECIES, AUTHORITY P. planus Trivedi & Verma ex Kalgutkar & Jansonius 2000.
LOCATION Near Kuala Lumpur, Malaysia.
ORIG DESCRIPTION* Fungal spores multicellular, two to many cells in a spore, length varies, shape of the spore varies, sometimes upper cells of the spore large and the lower ones small, narrow (pl. 1, fig. 9), sometimes spores longer than broad, sometimes curved at the middle or at some other place, but all have flat septa or nearly dentate; wall smooth, less than 1 µm wide, dark colored. Size of the different spores varies according to their shape. Length ranges from 66-99 µm, breadth 25-36 µm in larger specimens, 16-22 µm in smaller cells, height of individual cell ranges from 8-15 µm.
COMMENTS* Pluricellaesporites planus differs from P. nodosus, P. elongatus, P. clarkei and P. glomeratus described by Srivastava (1968) in its shape, size and nature of septa. P. planus also differs from P. dentatus in having flat septa, with very small or without septal opening. The specific name planus is given because of the flat septa of the spores.

K&J REMARKS Name of species not validly published in 1970, because Trivedi & Verma did not designate a single holotype. Kalgutkar and Jansonius (2000) illustrate pl. 1, fig. 15, and designate it as the lectotype. It is stored on preparation ML 58/2, which is kept in the collection of Dr. B.S. Trivedi (fide Trivedi & Verma, l.c.). The other three spores illustrated under this name in 1970 do not appear to be conspecific with the type.
