Pinewood Gingertail (Xeromphalina enigmatica not Xeromphalina campanella)

Xeromphalina enigmatica



We now have DNA sequences from 36 of the 495 specimens submitted in 2023. The results returned this week were largely as anticipated or inconclusive, making their significance challenging to assess. However, one significant result was the sequence of a Pinewood Gingertail (Xeromphalina campanella) specimen. This species is fairly common across PEI with 37 observations of Xeromphalina species, 28 of which are Xeromphalina campanella, in 24 Atlas squares.

Xeromphalina are easy to identify:

  • Small size, typically found on decaying wood such as stumps, frequently in large clusters.
  • Wiry stem, dark brown at the base, transitioning to yellow towards the top, culminating in a yellow/golden cap.
  • Fuzzy base.
  • Gills that are spaced out, decurrent (extending down the stem), with cross veins between the gills.
  • Produces a white spore print.



Guidebooks often highlight two common species: Xeromphalina campanella, found on softwood, and Xeromphalina kauffmanii, which prefers hardwood. However, recent sequencing of specimens from Newfoundland and Quebec revealed they are actually a different species, Xeromphalina enigmatica, which will grow on both types of wood. To verify if this phenomenon extends to our area, I included a specimen in our 2023 collection for analysis. The results confirmed our specimen to be X. enigmatica, aligning with these recent discoveries.

This revelation challenges our understanding of the geographical distribution of Xeromphalina campanella, necessitating further DNA sequencing for accurate identification due to the lack of visible differences between X. campanella and X. enigmatica. Given the findings, it's reasonable to presume that PEI predominantly hosts X. enigmatica, rather than X. campanella. Additionally, X. kauffmanii, documented in Nova Scotia and distinguishable by its larger spores, could potentially be present in PEI.

If you encounter a Pinewood Gingertail on hardwood, please collect samples or contact me for collection and DNA analysis in 2024.

New DNA results: Cortinarius "torvus-IN01"

A new DNA sequence has trickled in, this time for Cortinarius "torvus-IN01" which was found at Strathgartney Provincial Park. This is currently the 23rd observation and a first for Atlantic Canada.

2023 in Review

2023 proved to be an exceptionally fruitful year for the Mushroom Atlas, and we owe a tremendous debt of gratitude to all who contributed observations and ventured into the province's lesser-observed regions. Over the past two years, we've seen a significant expansion in our Atlas squares, boasting 20 research-grade species, soaring from just 13 to an impressive 62!

Key achievements of 2023 include:

  • A remarkable addition of 5,321 macrofungi observations to iNaturalist.
  • Year two of the Coastal Sand Dune Inventory met and surpassed expectations with 81 potential species.
  • A total of 495 specimens were provided for DNA sequencing analysis.
  • Psathyrella epimyces was observed, a target of the FunDiS Northeast Rare Fungi Challenge, marking the first observation for Atlantic Canada.

Other exciting finds are anticipated to be announced as our DNA sequencing analysis are completed. Among the first notable discoveries is Hydnum subolympicum, an uncommon hedgehog mushroom. While it is more common in the eastern United States, this species is uncommon in Atlantic Canada, with only six known observations to date: Newfoundland & Labrador (2), New Brunswick (2), Nova Scotia (1), and Prince Edward Island (1).

Fall Mycoblitz Success

We have gathered an estimated 300 specimens for the Fall Continental Mycoblitz, plus many other observations added to the inaturalist project. Great work!

While many interesting fungi were found, one of those observations was a target of the FunDiS Northeast Rare Fungi Challenge, the Parasitic Psathyrella (Psathyrella epimyces), found growing on a shaggy mane mushroom it had parasitized. You may learn more about this mushroom, and the FunDIS Challenge by clicking on the image below.

Observing past last years total!

We have passed last years total observations by almost 300 observations and another good month of mushroom weather to go, not to mention the Mycoblitz happening this week! Great work everyone.

October 13-22, 2023 - Continental Mycoblitz on PEI

October 13-22, 2023 - Continental Mycoblitz on PEI

Nature PEI will be participating in the 2023 Continental Mycoblitz, between Oct 13-22, 2023. Mycologists in the three Maritime Provinces will coordinate the Mycoblitz efforts in our region, to try sequence over 1,000 collections of mushrooms from New Brunswick, Nova Scotia and Prince Edward Island. This Mycoblitz is a unique opportunity to officially document PEI's fungal diversity.

There are two ways you can participate:

1) Between October 13-22, get out and document, on iNaturalist, all the fungi you can find. Please remember the helpful tips to maximize our ability to confirm identification.

and/or

1) Between October 13-22, collect specimens for DNA sequencing. Specimens collected must be documented on iNaturalist and an excel datasheet, and dehydrated completely, to cracker dry.

If you own a dehydrator and would like to be involved in collecting specimens, contact Ken Sanderson at ken@mushroomsofpei.ca.

Two events will be held as part of the Mycoblitz:

October 14, 2023 1:30 - 4:30 – (RAIN OR SHINE) Rosemary Curley will host a mushroom walk at Souris Striders Clubhhouse, Souris Line Road. Register with Chris Ortenburger chris@naturepei.ca

October 21, 2023 10:00 - 1:00 - (RAIN OR SHINE) Ken Sanderson will lead a blitz of Strathgartney Provincial Park. Participants will spread out to various different trails and habitats in the area and reconvene to go over what was found. Registration in advance is required by emailing: ken@mushroomsofpei.ca

Mycoblitz 2023 - in progress

The problem with inviting a bunch of cool people to come help you blitz a park is all the samples to go through!

Amanita's done. Boletes done. Polypores and the other oddballs done.

Gilled LBMs, Russula's, Laccaria, and waxcap's still to go:

Observation Reminders

Hope everyone is enjoying the start of the mushroom season! A couple reminders when adding mushroom observations to iNaturalist. Pictures of all parts of the fungi are often required, as are pictures or information on its habitat, such as type of tree it is growing on or beside. When making observations please double check the location and accuracy of your observation. Accuracy under 500m is required for inclusion in the Atlas project. A guide on what to keep in mind when you make an observation:

We will be participating in two mycoblitz's this year, one in August and one in October. I will provide more details as we get closer, but looking to hear from anyone interesting in helping. Observations will be made to iNaturalist during the time period and we will need to collect specimens for many, dehydrate them, and then send away for DNA sequencing. Let me know if you have a dehydrator you can use to dry mushrooms, or if you live close you can drop it off. This is a great opportunity to document our diversity.
