Type.
AUSTRALIA, Western Australia, Kununurra, Mulligan’s Lagoon Road, on Echinochloa kimberleyensis , 9 Apr. 2008, A.R. McTaggart, V.L. Challinor, A.D.W. Geering, M.D.E. Shivas & R.G. Shivas leg. (holotype: BRIP 51843).
Etymology.
Named after the Kimberley region of northern Western Australia from where it was collected.
Description.
Sori in some of the ovaries, often deciduous, globose to ovoid, 3-6 × 2-4 mm, green at first, later brown, smooth, ruptures irregularly to reveal a granular, dark brown mass of spore balls; columella absent. Spore balls subglobose, ovoid, elongate or irregular, 275-100 µm diam, dark brown, composed of up to several hundred spores, separated by moderate pressure. Spore globose, ovoid to irregular, slightly polyhedral, (9-) 9.5-12 (-14.5) × (8-) 8.5-9.5 (-10) μm (xˉ = 10.5 ± 1.2 × 8.9 ± 0.7 μm, n = 50), subhyaline to yellowish brown, attached together by multiple narrow cylindrical protuberances about 2 μm wide and 1-2 μm long; wall with irregular meshes and wings, 0.5 μm thick, smooth.
Additional specimen examined.
AUSTRALIA, Western Australia, Kununurra, Mulligan’s Lagoon Road, on E. kimberleyensis , 7 May 2009, A.R. McTaggart, M.J. Ryley, M.D.E. Shivas & R.G. Shivas leg. (BRIP 52498).
Notes.
Moesziomyces kimberleyensis was shown in the phylogenetic analysis to reside in a well-supported clade sister to M. bullatus . Moesziomyces kimberleyensis is only known from the teleomorph, which forms sori in flowers of E. kimberleyensis , and thereby differs from M. bullatus by host association. Moesziomyces kimberleyensis is only known from one location in Western Australia on E. kimberleyensis , which is an endemic grass in the tropical and subtropical woodlands of northern Australia.
