distribution, persistence, Phyllachora, Poaceae
Phytlachora spp. on Poaceae were collected to determine species present, grass hosts and distribution in Iowa. From 1959-1996 the fungus was collected 240 times from 67 different sites in 35 counties. Seven species of Phytlachora were collected on 25 species from 13 genera of grasses. P. graminis was collected 89 times from 43 sites on four species of Agropyron, two species of Calamagrostis, three species of Elymus, Hystrix patula, Panicum virgatum, and Setaria glauca. Seventy-two specimens of P. luteo-maculata on Andropogon gerardii or Schiziichyrium scoparium were collected from 30 sites. The study included 20 collections of P. cynodontis on Bouteloua curtipendula from 12 sites. P. vulgata was represented by 43 collections from 21 sites on Muhlenbergia species, and P. paspalicola was collected on Paspalum spp. 13 times from five sites. P. punctum was collected once on Dicanthelium oligosanthes var. scribnerianum, and once on Panicum capillare. The study included only one collection of P. phalaridis on Phalaris arundinacea. P. paspalicola and P. phalaridis are new records for the state.
