Christian, thank you for the info.

Thank you for remembering just how important the habitat info is. My
similar collection comes also from USC’s upper campus and the area was
strictly Quercus. When I saw my collection I thought that this is an
imported European Cort that has come with the host, something from the
Mediterranean possibly, as they have such colorful Corts down
there. But the Oaks were Californian. I have never seen this one in
another place and will be very interested to hear if someone finds
such one. Prof. Ammirati tells me that he has collected such in Costa
Rica under Oaks too. I have calochrous collections from the High Sierra
under conifers, but they’re a completely different beast.

Hi all,
I recognized this collection as one of only two Corts I brought to the Fair. I thought Dimi might be interested in the habitat that I collected it from, so:

Primarily Tanoak with Douglas-Fir, there may have been Quercus in the area, too. East side of Chinquapin Road, about 100 yards above the Firehouse, UCSC Upper Campus.

You’re right Dimi

It’s definitely a calochrous in a wide sense, and as you say – how to narrow them down, depends on who you ask. Not even the red KOH reaction is always there. It seems only useful when you try to get closer to species.
I don’t know anymore what literature to trust. Those who actually work on this group, tend to change their opinions about what is what every second year or so..

Definitely in the Calochrous group

Hi Irene,

good question. I always carry KOH with me for quick and dirty
help in such cases — this one had a pink/red reaction on the
cap. I am sure that this is the same as what I call C. catharinae
form the Santa Cruz area (under Live Oak).

Yes, it could have been anyone form the 50-255 members of that
Calochrous group, depending on who you ask, but since these have
not been studied from our area, it just made sense to use a base
name like C. calochrous without getting more fancy. Also, please
keep in mind that the people there have pre-printed labels and
like to use those. I will publish some of the Santa Cruz Cort
photos and discuss them and some of the questions related to them
on MushroomTalk when I have a chance. Just have to mention that
it was an extremely rewarding experience seeing some good
material that was new to me. From now I will attend many more
such fairs and see what’s going on.

Dimi came down for the Fair, and he is responsible for the name…

he also very much wanted to take this one away with him, but sacrificed his desires for the common good. He thought (and we agree) that it would be nice for the public to see such a beautiful cort on display.

ps I had made up a little sign that said “save for Dimi” but as evidenced by Allen’s photo, it got lost in the shuffle. Sometimes, sacrifice is painful!

Gorgeous gill colour!

I’m curious to know how this was ID:d. Could be something in the calochrous group – or not..
