No specimen available

a Helvella Jelly Baby ???

I have no clue as to what this is. I’ve been thru many references, finding nothing like it. It appears to have a stalk somewhat like Helvella and a rather viscid orange cap which looks somewhat like a ‘Jelly Baby’ Leotia lubrica, with one big exception; it has gills. The stalk is approx. 6 cm tall, the cap 2 cm. It was found September 14th, 2008 at the base of a very large old hardwood tree in Boone Co. Central Missouri. The immediate area was fertile in that there were several other different mushrooms growing nearby (sorry, don’t recall specifically what they were).

Any IDea ???

After looking at all the online resources, I very much favor the ID of (Rhodo)Collybia butyracea or distorta, commonly named ‘Butter Cap’ or even the ‘Greasy Toughshank’.

Here are some links as reference:




It looks like Tom Volk’s suggestion of a Gymnopus species, if traced to G. dryophilus is also very close. Michael Kuo devotes a page to trying to separate the two; that is Rhodocollybia butyracea from Gymnopus dryophilus.


Arora has a good discussion where he deals with G. dryophilus, C. butyracea & C. distorta.


He also specifically mentions the buff-colored stem in young specimens, as well as the twisted, hollow stalk. (How else would you get a mushroom to look like the one I pictured ???) I think it’s safe to say that the one I found is a young specimen where the cap hasn’t expanded to what one would normally recognize as a Collybia shape. I could find no pictures which resembled the crazy distorted stalk with that greasy cap. I certainly wasn’t alone, because quite a few folks I showed this to were like me, having no clue. But thanks to Dave W, I think he’s provided the thread to the best ID match: (Rhodo)Collybia butyracea or distorta.

My guess was something close to Collybia butyracea. But the stem color is much lighter than the cap color; something not generally seen in this species (at least not by me). Actually, as for the stalk, species of Hygrocybe sometimes exhibit the compressed/collapsed stem.

Tom Volk took a look and said he wasn’t sure what it is, but maybe Gymnopus, maybe poorly developed due to weather/environment. Other input has included Collybia (butyracea), and there are characteristics from R.Phillips (p. 143) and Arora (p. 429) which may apply from Cortinarius vibratilis (Myxacium subgenus) with a viscid cap and fleshy stalk, which can broaded at the base. I know the ID is still all over the map, but nothing is obvious. That’s why I’m posting it here to see what you think.

Thanks Mycowalt !

The cap certainly is Hygrocybe enough, but ever see a stem like that on one (or on anything with gills) ???

Thanks Danny for taking a look

sorry no spore print – best I can tell the gills are not attached

…neat as heck.No idea of the genus.Spore print them?The gills look serrated,are they attached?
