Abstract

Scutellospora hawaiiensis, a species common in coastal sand dunes of Hawaii, is described. The pale orange-brown to red-brown spores have six walls; an outermost unit wall (1.2-2.0 μm thick) appressed to a laminated wall (0.8-2.2 μm), a coriaceous wall (2.8-4.8 μm), a new type of wall (the "notching wall") (0.5-1.6 μm), whose broken edges consist of a series of rectangular and V-shaped notches, resembling a torn linen cloth, a coriaceous wall (2.0-3.3 μm) and a thick amorphous wall (3.0-4.0 μm, expanding up to 88 μm when crushed in acidic mountants).
