Observation 69397: Entoloma subgenus “Paraeccilia”

When: 2011-06-14

Collection location: Yosemite National Park, California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

These were growing on the ground near mixed conifers @ ~ 4500 ft.
The caps were smallish and pliant, up to 3.2 cm across.
Could not get a spore print but they appeared to be whitish to pinkish.
Spores were angular and ~ 11.0-12.0 X 8.0-8.9 microns.
Could not see any Cheilocystidia.
They seem to match Largent’s Paraeccilia concept but I was not able to match them up with any of his listed species.
Will add them to the Yosemite collections..# YNP1521.

…the english site is here: http://entoloma.nl/html/entinrtoeng.html – I forget the language differences. If you or another one could determine your finding please upgrade this data at MO. Because for me it’s very interesting to see Entoloma collections outside Europe.

Regards, Andreas

Thanks Andreas, That is a good site

and I think I’ve seen an English version somewhere.
I didn’t do anything more than look at the spores and a quick shot at the gills.
There wasn’t much left to these so I think I’ll save them for someone who might be better qualified to do the additional microscopy, etc.
I doubt I’d be able to put a firm name on them anyway just based on what has been published for our western North American species.

Characteristics of the pilleipellis?

What about the pilleipellis? I don’t know if this helps but I’ll try to check the Noordeloos-key of the European Entoloma species after you give me some informations about the pilleipellis. Perhaps this species lives also there.

You could find definitions of Entoloma characteristics at Noordeloos’ Website: http://entoloma.nl/html/entintroge.html – you could translate this page from German to English with Google Translator or another webtool. I need:

- Structure of pilleipellis (e.g. cutis, trichoderm, calliderm, perhaps any transitions, often in the centre of the pileus)
- Length and with of the hyphae elements
- Clamps at the septa or not
- Pigmentation type or types

By the way: Noordeloos’ classification site is outdated, the actual key is in his book “Entoloma s.l. Supplemento. Fungi Europaei 5A.”

Entoloma concept

All of the segregate genera used in the USA in the past have been lumped into Entoloma by recent European authors. Because of that, they were deprecated here on MO.

Is there some reason why the genus name Paraecillia

has been deprecated?
