will be an area to watch for quite some time. It’s amazing what a profound effect DNA analysis has had on the field of mycology … discovering and naming a new “tree of life” for fungi. Must be an exciting time for mycologists.

The Inocybaceae

consists of 7 clades, very consistently supported in recent research. 3 of them (“Nothocybe”, Auritella, and Tubariomyces) have not been found in North America. The other 4 are traditionally part of Inocybe but will likely get their own genera:

Inocybe sensu stricto = most Inocybe species
“Pseudosperma” = Inocybe rimosa and close allies
(Inocybe subgenus) Inosperma = I. adaequata, calamistrata, maculata, etc.
(Inocybe subgenus) Mallocybe = I. dulcamara, terrigena, unicolor, etc.

This obs is in the rimosa group, which AFAIK doesn’t have a better scientific name than the provisional “Pseudosperma”. You can see how it’s used in any paper that comes up from a Google Scholar search.

Wow! That raises a whole lot of questions for me, Jacob.

Very interesting. Do you have a link to some info on this classification that might help me understand what has been discovered regarding a new clade here … that possibly includes the specimens in this Ob.? Wouldn’t DNA be required before suggesting this “name” for an observation?
