This was in between the two observations from 20090226 (observation 18913 and observation 19808). All three observations were right along the trail, all in the same valley (Valle de Andorra) just a few miles north of Ushuaia. All were in deep Nothofagus pumilio, forest probably around 1000’ in elevation.

Note, there are three fruiting bodies pictured here, all within a few yards of each other:

1) images 40085-7
2) images 40088-9
3) images 40090-3

The “blade” is 4 cm

If you look really close, you can make out the marks on the “blade”, which is actually a ruler. They never show up very well though. The blade is just under 4 cm; the entire length is just over 9 cm (9.3 according to my calculations using Gimp).

Best dried material…

A pair of these specimens were the most well-dried of all the material Jason sent from Tierra del Fuego. These photos make a realistic description possible. Notice the pin-striped pants these guys are wearing. Apparently, that is a phenomenon only seen in a few of the large-spored amanitas of sect. Amanita from the southern cone of South America. (If someone has seen it in Australian or South African material of the same section, I’d really love to see the pictures). This pin-striped character is clearly depicted for both of the possible taxa that Jason photographed, but is mentioned in none of the original descriptions or field notes in a manner that conveys the actuality. Jason, what good fortune for Amanita that you took your trip.

Is the image 40089, flipped?
