“…Studies on compatibility among Armillaria species frequently indicate a low-frequency compatibility among isolates ascribed to separate species. Examples of low-frequency compatibility include isolates of A. sinapina paired with isolates of A. cepistipes, NABS X , or NABS XI (Anderson et al 1980, Banik and Burdsall 1998, Bkrubk et a1 1996. Isolates of A. cepistipes have shown a lowfrequency compatibility with isolates of NABS X (Anderson et al 1980, McDonald et al 1998, and NABS X isolates have shown low-frequency compatibility with NABS XI isolates (Banik and Burdsall 1998).…”

Although low-frequency compatibility does not necessarily indicate conspecificity, it does represent a possible mechanism for gene flow among species.…”

“…Their PCR-based method is especially practical because mycelial scrapings frequently provide sufficient template DNA for species identification. Subsequently, this method has been widely applied to augment identification of Armillaria species (Banik and Burdsall 1998, Banik et a1 1996, Baumgartner et a1 1997, Frontz et a1 1998, Sung et a1 1997, Volk et a1 1996, White et al 1998.…”

"Use of flow cytometry, fluorescence microscopy, and PCR-based techniques to assess intraspecific and interspecific matings of Armillaria species" (2001 For assessments of intraspecific mating using flow cytometry and fluorescence microscopy, two compatible basidiospore-derived isolates were selected from each of four parental basidiomata of North American Biological Species (NABS) X. The nuclear status in NABS X varied with basidiospore-derived isolates. Nuclei within basidiospore-derived isolates existed as haploids, diploids (doubled haploids), or a mixture of haploids and diploids (doubled haploids). Depending on the nuclear status of the basidiospore-derived lines of NABS X, intraspecifically mated cultures can exist as diploids or tetraploids, and possibly triploids or aneuploids under in vitro conditions. Based on previous in vitro mating studies, seven basidiospore isolates were specifically selected to assess rare, interspecific mating among Armillaria cepistipes, A. sinapina, NABS X, and NABS XI. Cultures from basidiospore-derived isolates were paired to produce four interspecifically paired cultures, and matings were assessed using flow cytometry and restriction fragment length polymorphism (RFLP) analyses. Based on flow cytometric analysis, the A. cepistipes isolate exhibited compatibility with a NABS X isolate, and the A. sinapina isolate exhibited compatibility with a NABS X isolate, and the A. sinapina isolates were individually compatible with isolates of NABS X and NABS XI. Mean fluorescence intensities of A. cepistipesiNABS X, A. sinapinaiNABS X, and A. sinapinaiNABS XI mated cultures revealed a triploid or tetraploid nuclear status compared to the haploid or diploid (doubled haploid) nuclear status of initial basidiospore-derived isolates. Polymerase chain reaction (PCR) and RFLP of the intergenic spacer (IGS) region generated banding patterns for basidiospore-derived isolates and mated cultures. Four species-specific RFLP banding patterns were observed in basidiospore-derived isolates of A. cepistipes, A. sinapina, NABS X, and NABS XI. PCR-RFLP analysis showed combined banding patterns from mated cultures. Flow cytometry and PCR-RFLP analysis are effective tools to assess matings of Armillaria species.
