Well, this seems to be a little early.

I have been collaborating with a number of folks on what I guess could be called the “rhacopus group.” There are a lot more species in this group than I expected. I think I had names for three or four; however, I think there are more than eight. While the smaller number was based on what I could see with my eyes, more collectors plus molecular tools are building up the number.

I am not looking for citrinoid taxa this year. (That research is moving into data compilation, data anaylsis, and writing stages.) However, I am looking for material of section Vaginatae, with a special interest in specimens that look like these photos of yours, brownish species with long marginal striations and a weakly structured volva that becomes grayish or darker over time.

Very best,
