Marantokordyana

Marantokordyana M. Piepenbr., Maike Hartmann, T.A. Hofm. & M. Lutz, in M. Piepenbr et al., Mycological Progress 19 (4): 357 (2020)

Etymology: The name refers to morphologically similar species of Kordyana and to the host family Marantaceae.

Diagnosis: Plant-parasitic fungi infecting species of Marantaceae. Fungal hyphae in intercellular spaces in leaves, causing yellowish spots without hypertrophic growth, filling substomatal chambers, protruding through stomatal openings. Basidia exposed on top of stomata on the abaxial side of leaf blades in spherical balls, mixed with paraphyses, each basidium with two straight sterigmata carrying one basidiospore each. Basidiospores blastosporic, with conspicuous hilum, without apiculus, cylindrical to slightly allantoid, often liberated in pairs, with one central septum at maturity. Basidiospores germinating with thin hyphae producing tiny, rod-shaped to fusiform conidia that multiply by budding yeast cells.
