Observation 154022: Lepista nuda (Bull.) Cooke
When: 2013-12-01
No herbarium specimen

Notes: Today I found these mushrooms I think are blewits. If so, they’re the smallest ones I’ve ever found (maybe 3/4" to 1 3/4" wide caps). Pictures attached and also here. Comments welcome.
Found near oak tree on lawn. Taste & odor not particularly distinct. Moist.
No spore print yet.

Older blewits…

do tend be more likely to be tan. I’ve seen examples of tan buttons, like the ones I got a week ago.

The ones in the next link came from the exact same spot, last year.

One is left to wonder if cold-weather blewits may develop more slowly than, and thus remain in the button stage for longer periods than cool-weather ones?

With some amanita species, cap color seems to react to sub-freezing or near-freezing temps. A chemical component may be temperature related. But some very purple blewits I’ve found have occurred very late in the season.

The color range for blewits…

is somewhat of a mystery to me. Most mushroom types that exhibit color range do so as a function of moisture content. But I have found… moist purple blewits, moist tan blewits, relatively dry (not dehydrated) purple blewits, relatively dry tan ones… with all these types observed both in shaded and open areas.

age tanned them, not the sun

I put my very purple picked blewits in the garage overnight. It kept them cool & a bit of the excessive moisture dissipated. As this happened, they tanned. So, the sun appears to be irrelevant, at least after picking, to the tanning process.
The 1st pics are before the garage, and the last picture shown here is from the day after.

which was mild up until the last week of the month, I collected blewits up until mid December. Link shows mushrooms collected very near where the other more recent linked collection was made. (See previous comment.)

Years back, when I was a grad student at SUNY Binghamton, I collected lots of blewits from the many small green spaces on campus… wood-chip islands with shrubs cut into the paved walking areas. These spots tend to soak up the heat from the sun. One time I found blewits growing from chips along a wooden border on January 20.

For the most part, I agree with Bill Neil’s assessment about compost generating heat etc. But the mushrooms I just picked yesterday were growing from the ground, on a well-exposed lawn. There have been hard freezes and a couple inches of snow at this location. Apparently, the mycelium survives underneath the surface, and when the ground temp comes back up, voila! I wonder just how deeply the ground needs to freeze in order to end the season?

Interesting. Bill Neil had replied to me here (http://tech.groups.yahoo.com/...) about late season ones. What’s the latest in the season you’ve found them, Dave?

reminded me to check my late blewit spot.

Mine are not as purple as the ones in this obs (154022). Amazing how these continue to fruit after the weather has turned so cold.

other than size, perhaps, they don’t have a cort feel to me.
