I was under the impression for a while that Rhizophagus irregularis was formerly known as Rhizophagus intraradices, but in Krueger et al 2012, it is shown that they are actually distinct. But I've read somewhere recently that only DAOM197198 is R. irregularis and the rest should be called R. intraradices. Is that correct? I was wondering if there's any distinct difference between them (morphological for example).
