CNM has Oudemansiella gigaspora group and Oudemansiella 'radicata group'. They're the same thing, so we ought to get rid of one of those names. I have no preference one way of the other. The radicata name happens to be what I used early on when the old radicata species was being split and the segregates shuffled between genera.

No problem either way you go, though agree should only be one otherwise can become confusing.. Though O. gigaspora seems to be the 'latest' preferred naming till things become clarified with what we are seeing in Australia. I wonder if we're not seeing more than one species or just environmental conditions etc that are giving such a wide range of pileus colour and size. I've noted some with hardly any 'root' at all and others with very distinct and long root.

In the classification of Yang et al. 2009 in Mycostema the species that looked like these came out in Oudemansiella Section Radicatae (which made identification to section [=group?] easy). However, a paper a year later seems to have changed all that, unfortunately I have no access to that huge body of work. See Petersen RH, Hughes KW (2010) The Xerula/Oudemansiella Complex (Agaricales). Nova
Hedwigia Beih. 137: 1–625. More recent works on the oudemansielloid/xeruloid taxa appear to follow the Petersen and Hughes 2010 paper e.g. Allen Grace T. Niego et al. in MycoKeys 98: 253–271 (2023). On looking at some of these recent works it seems likely that the current genus name for most species in Australia is Hymenopellis. I suspect that neither Oudemansiella gigaspora group and Oudemansiella 'radicata group' is acceptable with respect to a modern classification. However, Oudemansiella 'radicata group' sort makes more sense using the Yang et al. 2009 classification where the Oudemansiella gigaspora group seems to have no basis. Unfortunately I suspect we will have trouble sorting this out until someone can look at the Petersen and Hughes paper.

We had to combine the two so, arbitrarily, I had Michael keep gigaspora . I had thought of getting it re-named to Oudemansiella 'annoying group'.
