Observation 32473: Limacella illinita (Fr. : Fr.) Murrill
When: 2010-01-23

Notes: Both the cap and the stem are extremely slimy. Its the slimiest stem I have ever seen.

Mild farinaceous odor, similar to cucumber.

Under redwood and tan oak.

Cap context stained with melzers. There were lots of air pockets.
Lamellar trama stained with melzers.
Gill face stained with melzers. This is the part of the gill where the pleurocystidia would be, though none were observed.

Notice the gray brown color of the gluten over the gills…

In the original description of Smith’s Limacella illinita var. argillacea (she wrongly considered that she was recombining a Friesian name), the color of the gluten on the cap is described as colorless, and that on the stipe as colorless to grayish. Her material did come largely from California and Oregon, but I can’t be sure that these images depict her taxon. Her original collections will have to be examined to obtain the microscopic characters, because in Dr. Smith’s 1945 article, she doesn’t provide any microscopic detail specific to her variety.

It seems (final image of upside down specimen) that the slime color maybe become pale gray over the gills (and, hence) on the stem.

Alan can you lift off a big chunk of goo and tell us what color it is (as opposed to what color the cap is with the goo on it)?

There is a species that was collected under redwood in San Mateo Co., but its description leaves out the color of the slime entirely: L. mcmurphyi Murrill. It is a very poorly known taxon, I’ve studied the type, and many characters cannot be described due to the type’s bad condition. I’d be very interested to see Alan’s material on the chance that it might give a meaning to the name L. mcmurphyi.


nice and gooey!

The species of Limacella that have been reported from northern California and the PNW of US and the SW of Canada are very interesting and include unusual taxa. They are also poorly understood. I’ve mentioned before that I would be very grateful for illustrated and annotated material of Limacella from this region.

oh man, ya shoulda collected a couple of these…
