Danny’s DNA Discoveries – Hypholoma of the PNW
by Danny Miller

Click here for my Pictorial Key to Hypholoma

Introduction

This portion of the large Hymenogastraceae family (or perhaps it should be called a super-family), formerly known as Naematoloma, are often yellow-brown, have non-viscid caps and purple brown sporesNot usually hygrophanous. Found on wood, moss, bogs or the ground.

Phaeonematoloma myosotis (formerly Hypholoma myosotis) has been separated out on the basis of genetics as well as a viscid cap and non-purplish spores and is found elsewhere. Other Hypholoma species may need to be moved too, but we await a multi-gene study to confirm this.

Bogbodia udu - with slightly warty spores that aren't even noticed very often, Hypholoma udum was placed into its own genus, but that doesn't seem to be born out by genetics, so some, including me, are going to wait before accepting it.

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:

  • several seemingly undescribed species have been found, some of which may actually belong in Phaeonematoloma.

First, the following Hypholomas have at least some of the viscidness and spore colour character of Phaeonematoloma, as well as sequencing 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.

Species mentioned: Phaeonematoloma myosotis. Hypholoma subochracea. Pholiota subochracea.
