Intraornatosporaceae (Gigasporales), a new family with two new genera and two new species
A new family (Intraornatosporaceae), two new genera (Intraornatospora, Paradentiscutata), two new species (P. bahiana, P. maritima), and a new combination (I. intraornata) are presented in the Gigasporales. The genera, both with diagnostic introverted ornamentations on the spore wall, are distinguished by spore wall structure and germ shield characteristics. The new species, detected in NE Brazil, can be differentiated by their projections on the outer spore surface. Partial sequences of the LSU rRNA gene place both species next to I. intraornata in a monophyletic major clade related to Gigasporaceae and Dentiscutataceae.
