SPECIES, AUTHORITY L. permagnus Parsons & Norris 1999, p. 114, pl. 2, fig. 15.
LOCATION Caribou Hills, Mackenzie River delta, Canada.
ORIG DESCRIPTION* Very large, vase-shaped to ellipsoidal monocellate spores with a circular attachment scar at one end and a simple pore, diameter 2-2.5 µm, at the other. A second, smaller pore may be present in the centre of the attachment scar. Spore wall psilate.

Only two of 19 specimens examined showed a pore in the attachment scar. Length 29-47 µm, width 17-33 µm; holotype 37 x 23 µm.
COMMENTS* This species is larger and less elongate than L. pseudoabruptus, and has a more prominent pore.

Derivation of name: From Latin permagnus, very large.
PUBLICATION REFERENCE Parsons MG, Norris G. 1999. Paleogene fungi from the Caribou Hills, Mackenzie Delta, northern Canada; Palaeontographica, Abt. B, v. 250, p. 77-167.
K&J REMARKS The occasional presence of a pore in the attachment scar is not a species-diagnostic character. A pore can always appear at the point where the spore was attached to the hypha or conidiophore.
