Observation 50632: Pluteus insidiosus Vellinga & Schreurs

When: 2010-08-09

Collection location: Lainzer Tiergarten, Wien, Austria [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Under mixed hardwood forests, mostly oak and beech.

Adding some micro-details:

The first micro-shot is of the cap surface at 400x in KOH. The cap surface is a hymeniderm, or globose to clavate elements, all rather even.

The second micro-shot is of the gill edge at 400x in KOH. There are cheilocystidia on a non-fertile edge, these are lageniform with a elongated “neck”, with a long pointy end. Similar pleurocystidia were also obs., along with 4-spored basidia on the gill face.

The third micro-shot is of spores from the gill at 1000x in KOH. The spores are ellipsoid, smooth, with out a germ pore. The apr. size is 7-6 × 5 um.

Not sure to do with all, and I can’t seem to find the Pluteus key from Flora Agaricina Neerlandica on-line anymore, I used to be able to find that. But looking in Funga Nordica at p342, that source suggests Pluteus insidiosus with these cystidia, the even hymeniderm cap and dark colors.

Your observation shows everything what one needs for ID of your specimen. This is a great example of the proper use of Mushroom Observer! Most of your observations are of this kind. Many thanks and congratulations! Adolf & Oluna
