Who: Cody Morgan (Cody)

Specimen available

Notes:
Ive found alot of what ive assumed is M. subcaerulea this year, however some of them seem to be alittle different.

Overall they seem much paler in color and the cap shape seems alittle different. The stems are really curvy and irregular, most of the stems were deeply buried in leaf litter/soil (half or more). Towards the base they are densely covered in hair like fibers that appear white but when touched/pushed aginst the stem they are a very vibrant blue/turquoise, I think they are blue to begin with you just cant tell until they have been disturbed.

The deeply rooting stem and stronger blue colors seem to fit M. amicta better, but maybe its just subcaerulea being really variable.

Any insights on these finds would be very much appreciated.

I didnt dig these out to see if the stems were deeply rooted so these could be different

Spore shape

The microscope I have currently is really just a cheap toy, although I can make out the general shape of spores usually. Once tax time comes around I will be getting a nicer one with a 100x oil immersion objective. My inability to check simple microscopic features has been a real hindrance!

Thank you for the information Dave.

says that subcaerulea spores are globose/subglobose (6-8 × 6-7); spores of amicta ellipsoid (7-9 × 4-5). So, you can probably settle this with 400×.

Thanks for weighing in on this, my gut feeling was that these are just wierd subcaerulea. I forgot to mention I couldnt locate any obvious pine debris but the area is littered with oak so I guess that makes amicta pretty unlikely. Out of the hundreds of subcaerulea ive seen this year these seemed quite different from what im used to seeing so your second opinion is appreciated.
Have you observed this type of deeply rooted strong bluing stem in any of your findings of this sp.? Its not something ive noticed before with my findings so it seems fairly rare for them to have these features. (Atleast from what ive seen in my area so far)
