Observation 223436: Mixed collection

When: 2015-11-19

Collection location: Longview Arboretum at Maude Cobb, Longview, Gregg Co, Texas, USA [Click for map]

Who: L G Price (LG_Price)

No specimen available

NOTE: all specimens will be thrown out as they can’t be sorted. They all grew in a circle about 3 foot diameter. I think most were Tricholoma but can’t be sure. I may make photos of the spore for each and add to the observation.

Habitat: Growning in wooded area under oaks

Smell: mild mushroom
Taste: did not
Chemical Test: did not

Spore Print: thick, rusty reddish-brown
Spore Photos, measurements: TBD

Staining: none from cutting, brown staining from insects.

Cap: Largest – 2.75 inches, glutinous on smaller caps, larger caps had leaves stuck to them as if adhered by glutinous material. Recent heavy rains probably washed away most of the glutinous material. Tightly inrolled at first flattening to convex at maturity. Brown with reddish tints. Context – off white to pale tan. None showed veil or cortina, even the smallest.

Gills: originally color matches cap context, darkening due to spore. close. shallow breadth.

Stalk: fibrous, thick – 2/3 of cap width early to 1/5 at maturity, hollowing. Swollen at base with many having tiny attached buds. No ring or marking due to ring or cortina.

I did not get a match when going through the keys in Tricholomas of N A.

I looked closely at the spore print this evening and there is both a white print and a red-brown print.

The collection is mixed. Probably both Cortinarius and Tricholoma.

Not sure how I will sort this out.

thanks for the comment.

I waited until this morning and yes the deposit is thick and reddish-brown.

Earlier there was a dusting of red-brown and I wondered if I had contaminated the plastic somehow.

I don’t have a good key for Cortinarius, but it seems the most likely even without a visible cortina on either the mature or tiny buttons.
