Several of these were found growing in a Bishop pine habitat.
I only brought 1 specimen home and had difficulty getting the dirt out of all the nooks and crannies.
As with MO#163095, I let this one age enough for the veil to tear and then got a spore print.
Spores were amyloid.
Also as with MO#163095, I measured the spores both in Melzers and then in Congo Red + KOH. Again the variation was fairly high for Q values but still below the average values reported for A. magniverrucata and appear to be wider.
Spores in Melzers; 9.8-12.2 X 7.0-9.2 microns Q(range) = 1.30-1.55. Q(9ave) = 1.40. n=21.
Spores in Congo Red + KOH; 8.3-11.8 X 7.0-9.4 Microns Q(range) = 1.15-1.39. Q(ave) = 1.24. n=20.
As Christian noted, in the field, I would be inclined to call all these A. magniverrucata.

We got a nice, complete “proposed fungal barcode” sequence as well as an nrLSU sequence of robust size and quality.
This was a very useful collection to us.
Thanks again for all the material you have sent to Roosevelt.
This material has been recieved and accessioned to Rods herbarium. We have scheduled it for DNA sequencing.
