Observation 373717: Lanmaoa G. Wu et al.

When: 2019-07-11

Collection location: North Park, Allegheny Co., Pennsylvania, USA [Click for map]

Who: Scott Pavelle (Scott Pavelle)

No specimen available

This one I don’t know off the top of my head. Smooth yellow stem with no markings. Bright yellow, very thin pore layer. Everything blues, but slowly and not very deeply. E.g., these photos were taken about a minute after the cuts were made. There was little, if any bruising with the immediate cut and scratch.

They were found under oak in a spot where I usually find frostii.

Any suggestions? These are very young and dense specimens.

Recognized by sight: Pseudosensibilis is a good possibility, especially if ammonia on cap gave a blue flash and the bluing of the exposed flesh resolved as a reddish-brown oxidation

Did you smell it?
Lanmaoa is becoming of interest to me because of some undescribed and poorly understood taxa (e.g., sensibilis and carminipes) that have recently emerged as a result of my sequencing effort.
In the future, try to take picture out of the sun, as it really distorts the colors. Scattered natural light even under light canopy works best.

The bluing resolved to nothing. Not brown, just gone.

The collection was made yesterday and the specimens discarded. No chemical tests.

I mention Roodyi only to prompt discussion

I have never met the critter in person, so I’m going solely by the book description and the photos.
