In my experience, it fruits irregularly. However, since it’s mycorrhizal, it fruits in the same general area (with its host tree(s)) when it does fruit. In New Jersey, we see it in pine-oak sandy barrens. Because of colonial and revolutionary logging for charcoal, the area is dominated by pitch pine, but small scrubby oaks are also present. The narrow spores and the deeply penetrating stem are often seen on species that evolved over long, long, long periods in sandy soiled, fire prone areas even if they are now growing in a slightly broader range. The pine oak forest of the Atlantic and Gulf of Mexico coastal plains (although ocean height has changed with time) have had very similar forests for a long time.

Very best,


Thanks Rod

I’ve had a chance to scrutinize the description for Amanita cylindrispora ; its a much better fit and seems to account for the deeply buried stipe which lead to my confusion on what section to place it in. I was setup to collect a few pounds of maitake nearby and did not collect this one. I plan to revisit soon and now that I have a better idea of what it could be I’ll be sure to save a specimen for you.

Just in case…

Do you have dried material?


If you take a look at the “materials examined” data field …

on the technical tab for the web page previously provided, you will see that Balitmore (my home town) is within the known range of cylindrispora along the Atlantic Coast.


The long stipe is very typical of Amanita cylindrispora.

With a microscope, if you do have cylindrispora you should find the spores are rather narrow (cylindric to bacilliform). The cap color will not turn yellow in KOH. The species does not contain amatoxin and is more like the lepidellas of Amanita subsection Limbatulae than it is like a member of the Phalloideae.
