ORIG DESCRIPTION* ORIGINAL DIAGNOSIS: [combined description] Conidia consisting of four tapered arms that end in an abruptly tapered sharp point and that radiate from a large central, polyhedral cell; apices of the arms corresponding to the apices of a more or less regular tetrahedron; arms subdivided by thick septa into three to five nearly equidimensional cells; one arm tip generally flattened, which presumably represents the point of attachment to the conidiophore; overall dimensions 60-90 µm.

EMENDED DIAGNOSIS (Kalgutkar & Jansonius 2000): Inaperturate, medium to large-sized conidia consisting of a large, inflated polyhedral (generally triangular or tetrahedral) central cell, the corners of which are extended into tapered arms consisting of some two to six nearly equidimensional cells; the radial arms closed terminally, rounded to pointed, but one arm generally with a flat (hilar?) end.
COMMENTS* The conidia resemble in structure and general form the conidia of extant genera Tetrachaetum and Lemonniera.
