Abstract/Contents: | "Twelve graminicolous species of Alternaria are described, illustrated and deyed by cultural and morphological characters. Ex-type, authentic or representative living material of Alternaria alternata, A. cetera, A. infectoria, A. longissima, A. metachromatica, A. oregonensis, A. padwickii, A. tenuissima, A. triticicola, A. triticimaculans, and A. triticina furnish the basis for descriptions and illustrations, as do type or authentic exsiccati of A. longissima, A. padwickii and A. saparva. Sporulation and other characters in available cultures and/or exsiccati of A. graminum, A. peglioni, and A. maritima were insufficient for construction of reliable descriptions. Five names are listed for well-characterized species that are of only incidental occurrence on Poaceae; an additional four names are listed for which material was unavailable. Strains of small-spored, chain-forming Alternaria spp. isolated from uncultivated grasses in Washington and Idaho, or from USDA-ARS seed accessions, frequently conformed to A. infectoria or A. tenuissima but only infrequently to A. alternata. No strains in precise conformity to A. alternata sensu Simmons were recovered. Not all strains conformed to descriptions derived from ex-type, authentic or representative material. Results from these morphological and cultural studies will be treated as hypotheses for work based on molecular methods." |
