Observation 121911: Russula ballouii Pk.

When: 2012-08-11

Collection location: Flemington, New Jersey, USA [Click for map]

Who: Linas Kudzma (baravykas)

Specimen available

Every year I find this distinctive scaly capped Russula sp. in this exact same location. I have never seen it elsewhere and it may be associated with a group of Honey Locust (Gleditsia triacanthos) trees which are uncommon in NJ. Taste is mild/mealy. Spores are subglobose with amyloid partially connected ornamentation (see photomicrograph). 20 Spore average is 7.2 × 6.3 microns; Qm =1.17.

For this species Kuo says very acrid and Rogers says mild on their respective sites. How can that be for a single species? My collection was mild and I called it “mealy”, but a description I just read said “like bread dough” and that fits. So do some photos in various locations on the web, including Russulales-News.

Thanks Walt ..
