Cudonia circinans

Cudonia circinans

Cudonia is one of several remote ascomycete genera with needly spores, and my find fit the description of Cudonia circinans, which grows under conifers and has a pale yellow to brownish cap, with a somewhat darker brown stem. Cudonia lutea, by contrast, is brighter yellow, grows under hardwoods, and has a stem colored like the cap. The definitive feature separating the two species, however, is spore size (over 50 µm long for Cudonia lutea and under 40 µm long for Cudonia circinans).
