This nice patch is right on the bank of Hwy 20. By the blue glaucous color and prostrate habit, I would say they are viscida x nevadensis @sapienshane @morganstickrod

Small mixed population of nevadensis, patula and viscida and some apparent hybrids. They didn't look like the nevadensis x viscida hybrids seen near by. Maybe patula involved? Very easy to get to these, they are right above Hwy 20 @sapienshane @morganstickrod

A. canescens x nevadensis ssp. nevadensis. Location is from memory, may be a little off, but they were right along the Happy Camp-O'Brien Rd. near the summit in plain sight. Both parent species next too hybrids. Area has recently burned. The road was closed this year. @sapienshane @morganstickrod

Location is from memory - could be slightly off. A. viscida ssp. pulchella and A. nevadensis knightii were in area and likely parent species. @sapienshane @morganstickrod

One of the most interesting hybrid swarms I have ever seen. Acres of extremely variable plants. A. nevadensis, mewukka, viscida, patula all present at this location. I've been trying to get Mike Vasey and Tom Parker to check out this spot for years! Not sure if any of the nevadensis is "pure" nevadensis. All of it seems to be integrated with other genes. Fairly low elevation for nevadensis for this region. A lot of other interesting plants also present at this location (Calochortus coeruleous, Calochortus nudus/minimus and hybrids between this one and coeruleous, Erythronium purpurescens - very low elevation for this one). @morganstickrod @dgreenberger

Apparent hybrid between nevadensis and mewukka var. mewukka. These plants have inflorescence similar to mewukka, burl, and low spreading habit like nevadensis. @morganstickrod

Globular stem gall on Microseris sp....most likely M. douglasii...but based on my photos, I'm currently unable to verify species using the Jepson eFlora key. The nodding heads and phyllaries in this CalPhotos image are a good match, though there is also a record of M. bigelovii from the locale. (As an aside, I found it amusing that the adaxial dark-red mid-ribs of the tepals in the Brodiaea terrestris growing here matched so well with the similar mid-ribs of the Microseris phyllaries ;-).

Beyond James Bailey's iNat post under Antistrophus microseris, the only reference I could find for a stem gall on Microseris is in:

McCracken, Isabel; Egbert, Dorothy (1922). "California gall-making Cynipidae, with descriptions of new species". Stanford University Publications, University Series, Biological Sciences. 3 (1): 5–70.

...where the original description of "Aylax microseris" is given on pg. 47. The species is referred to as Antistrophus microseris on this Wikipedia page...a name change also recognized on iNat.

The gall is described as "an irregular stem swelling" of "diameter 10-20 mm" and "length 20-30 mm", and is illustrated in Plate 1, Fig. 10 (to view, scroll down 3 pages from here). The gall here doesn't seem particularly irregular to me, and Fig. 10 shows longitudinal veins I see only vaguely intimated in the photo...but overall the match seems the best current alternative out there. The locale here is only a few miles from the type locality of Aylax microseris.
