About mushroom

Mycena leaiana (Berk.) Sacc. Cap 1-5cm across, bell-shaped becoming convex, with center sometimes depressed; bright reddish orange becoming more yellow in age; slimy, shiny, smooth. Gills adnate, close to crowded, broad; dirty yellow-pink, staining orange-yellow when cut, with bright red-orange edges. Stem 30-70 x 1-3mm, tough, fibrous; orange to yellow, paler near apex, exuding a little watery, orange juice; slimy and somewhat sticky with base covered in dense, coarse hairs. Flesh thickish, pliant; white beneath the orange cuticle. Odor faintly mealy. Taste slight. Spores ellipsoid, amyloid, 7-10 x 5-6-. Deposit white. Habitat in dense clusters on deciduous wood. Common. Throughout central and eastern states of North America. Season f one-September. Edibility not known- avoid.


This month's fungi, Mycena leaiana, is a great mushroom to find in the woods. It's shiny orange, with glowing orange marginate gills (more on that later), and therefore often sticks out from an extended distance. Despite the fact that the mushrooms themselves are very small at maturity, usually significantly less than an inch (3 cm) in diameter, they could be very prolific fruiters, so there is a huge amount of it to be seen often. Even in dry weather you could find it since it uses this found very deep in the log to create its fruiting bodies. Understand that mushrooms are 90-95% normal water, so if there is no drinking water there are no mushrooms, but Mycena leaiana appears to be an excellent scavenger of drinking water through its mycelium from solid wood.

The edibility of the fungus is unidentified, but is as yet not known to be poisonous. That said, there appears to be nothing at all to recommend it for the stand anyway, since it is rather small and has a fairly rubbery surface if you make an effort to cut it. The orange color comes off on the hands when you touch it, and it might be dreamed by me would do the same in the mouth area.

So how about these marginate gills? If you look on the lower of the mushroom, you can view that the gills are orange. This seems just like a contradiction, because the spore printing is white. In the event that you look just a little deeper however, e.g. with a side lens, you can view that the orange color is mainly limited to the advantage of the gills. A straight closer look with a microscope reveals that the orange pigment is mainly limited to cystidia, sterile cells at the edge of the gill. Cystidia on the border of the gill are medically called "cheilocystidia" (practically, "lip cystidia"). Compare these to the "pleurocystidia" ("part cystidia") entirely on (you guessed it) the attributes of the gills of Pluteus cervinus.

Observe that the strikingly beautiful orange cystidia include almost all of the advantage of the gill, offering this varieties its quality orange margin. However if you look from the gill advantage toward the basidia (basidiospore producing set ups), you will get some wayward orange cystidia borne singly on the list of basidia often.
