Flesh greyish white, soft, turgid, moderatly thin. No detectable odor or taste. Stipe yellowish when cleaned and appears to have whitish rhizoides. Stipes 2-5 mm at apex with a long radicated root. 4-9.5 cm long. hollow, flexible. Lowere stipe appears to be coated with brownish black particles and has side branches. Terrestrial by Rose of Sharon (Hybiscus syriacus). I retrieved more yesterday and some were on buried wood. Spore color white. Spoe sizes were 6-8um long x 3-4um wide, but there were many larger spores measuring 12-13um x 6-6.6um. Can’t tell if the smaller spores were immature due to the small size of thes specimens. Each occular ~ 1 um.

for clarifying this obs. I considered F. velutipes but had never found that species with the long radicating stipe. Had me totally confused.
