The volval sac seems to be rather robust. At least it’s not breaking up into fragments or tearing. There is a northeastern species that I think I can tell in the field because of the weakly structured volval sac that I’ve called A. rasitabula.

Very best,

As a general rule, I am very interested in getting a look at taxa in sect. Vaginatae sensu Yang (that is to say, excluding sect. Caesareae, which was not segregated back in the 1960’s by Dr. Bas).

White or whitish taxa in particular are very hard to separate from images. Genetics tells us that there are several of them. Some of the data is too limited to sort out. However, we do have a local database that we are using to sort those sequences that we are able to obtain.

If you have dried material associate with this observation and would be willing to share some or all of it, I would be very interested in investigatin this critter further.

Very best,

Rod
