spindly yellow Clavaria emerging from soil under a shaded shrub/ thick grass, a semi-restored tall grass prairie

sequencing is in the works, will update observation later

Additional notes from dried specimen 2017-01-27

-1.5cm tall, ~1mm wide max
-has slightly darker and narrower “stalk” at base, upper hymenophore paler (see 2nd image especially – the “V” pair)
-no 10% KOH reaction on dried material compared with dH2O (Kuo notes a greenish colour change for C. laeticolor)

-Few spores on specimen but definitely apiculate, mostly kind of round tear shaped subglobose to longer and somewhat elliptical, appeared smooth as far as I could tell (not “tuberculate” for C. helvola)
-When it came to measuring only found three before giving up, were rolling around while trying to measure so avg dimensions only for a vague idea… Averages: Length 5.2um, Width 3.8um (C. gracillima is 5.5-8.5 × 3-4.5 in Smith & Smith reference)
