Danny’s DNA Discoveries – Alnicola (Naucoria), Meottomyces and Phaeonematoloma of the PNW
by Danny Miller

(there's not much call for a picture key of species)

Introduction

Here are a few interesting miscellaneous genera in the large Hymenogastraceae family (or perhaps it should be called a super-family).

Alnicola (Naucoria) - unusual LBMs that are mycorrhizal, perhaps you'll be able to recognize them from among the myraid other LBMs by their tendency to have a flat cap and grow under alder and willow. Naucoria seems to be the older name, but some sources are still using Alnicola. I await a final ruling.

Meottomyces - only recently discovered in the PNW, they are small to medium sized on the ground with a greasy to sticky cap and and no unusual odor (unlike the similar Hebeloma).

Phaeonematoloma - a little more slender small to medium mushroom, definitely a viscid cap (and stem) and brown spores. Our most common one is olive colouredumbonate and growing in moss.

abundant  common  uncommon  rare - colour codes match my Pictorial Key and are my opinions and probably reflect my bias of living in W WA. Rare species may be locally common in certain places at certain times.

Summary of Interesting Results

Here are some of the newest, most interesting results of the study:

Alnicola (Naucoria) - click to expand

For a non descript LBM, Alnicola has been studied quite extensively in Europe by Moreau, so we have good sequences of many species... yet still many of ours our turning out to be different undescribed species.

I also include some Hypholomas besides Phaeonematoloma myosotis (like Hypholoma subochracea and some undescribed species) that have at least some of the viscidness and spore colour character of Phaeonematoloma, that sequence somewhat close to that genus. We need a multi-gene study to confirm where these species belong. For now, I cover some of them on two pages.
