I walked through Kin Beach Park a few days ago and was struck by the winter colours and how striking the silvers and rusts were against the green of the mosses.

Cortinarius is the biggest genus of gilled mushrooms in the world, with thousands of species. The Pacific coast is a hotspot for “corts,” with a rich abundance and diversity. A few distinct features of this genus:
Many have a “cortina” (from the Latin word for curtain) that forms a cobweb-like veil over the developing gills. Traces of the veil often appear as a ring-like band of fibrils on the stipe (stem).
Spore prints are typically rusty-brown.
All grow in soil or humus (never on wood) and are ectomycorrhizal.
Species in this genus come in a variety of sizes and colours. Some have brightly coloured gills (yellow, orange, red), and others have shades of green, lilac or purple. In a shaft of sunlight the gills can be spectacularly bright and satiny. Many more species are brown & dull, and these have a more subtle beauty.
Here are some examples of Cortinarius that I have seen this fall. These are all from four locations: Buttle Lake area, lakes north of Campbell River, the Merville Woods, and Miracle Beach Park. Note that #6 & 7 are a review of the lilac and purple corts discussed by Alison earlier in her debrief on green, blue and purple shrooms.

This yellow-gilled cort might be Cortinarius croceus.
An orangy-gilled cort, possibly Cortinarius cinnamomomeus.
A red-gilled cort, likely Cortinarius smithii.
Close-up of the red gills of the above.
A beautiful “viscid” cort that looks like it is covered in a glaze (which reflects the canopy above!) Possibly Cortinarius vanduzerensis. Note the purple blush at the base of the stipe.
A lilac-coloured cort (there are many different lilac-toned species, which all look very similar!). Note the cortina on the stipe, which shows nicely here.

Here are some fly agarics (Amanita muscaria) growing in an unusual spot! (More down the hole, but I didn’t look too closely.) You never know where this cosmopolitan shroom will pop up!
I have seen a variety of button forms of this iconic species…some studded with warts, some hot-orange without warts, and others the size of an orange. Always interesting! Here are photos of some fly agaric forms:
Warty button
Wartless button
Orange-sized
Classic amanitas (from the edge of a Comox parking lot)
There is nothing else that really looks like the fly agaric, though I was almost fooled by a tricholoma (I think this might be Tricholoma zelleri which in some books is the same thing as Tricholoma focale) at Merville Woods the other day. It was large and bright orange, but had a more slimy cap, and scaly stipe.
On May 14 of this year, CVN’s guest speaker Dr. John Reynolds presented a very informative webinar on how to use the iNaturalist online platform for recording and viewing nature observations from around the world. Following the tutorial part of the presentation, John discussed and showed examples of the BC Parks project in iNaturalist.
If you missed this presentation (or want to see it again), a recording is available at this location. You only need to provide your name and email address to have access to it.
iNaturalist is photo-based — just take a photo of any animal, plant or fungus that you observe and upload it to the platform. It has both a smartphone app and a website. Anybody can use the system. If you can’t provide an identification of the species yourself, iNaturalist has a recognition function that can suggest the identity. Other members will help with the identification if needed, and after another member confirms the identification, your observation becomes “research grade” and can be used by researchers.
Many geographically defined “projects” exist in iNaturalist. Using the location information associated with your photo, iNaturalist automatically adds it to any relevant projects.
CVN strongly encourages our members to participate in iNaturalist, and this presentation is a great way to get started. Also, you can find references to other iNaturalist resources in this earlier post.
Comox Valley Nature is pleased to host a free online lecture by Natalie Mahara. The lecture entitled “Establishing a baseline of microplastics in marine food webs: a case study in Baynes Sound, B.C.” is on Sunday November 15, 2020, 7:00 – 9:00pm.
Given the current situation with the Covid-19 virus, Comox Valley Nature has made arrangements to have a live, online webinar for Natalie’s presentation. You will need to pre-register:
Microplastics have emerged as one of the most ubiquitous global pollutants and can enter the marine food web either via direct consumption or by trophic transfer by consuming animals that have taken up microplastics. Researchers from the University of British Columbia worked closely with the Association for Denman Island Marine Stewards and the K’ómoks Guardian Watchmen in 2019 to establish a baseline of microplastic concentration and composition in and around Baynes Sound, and to estimate microplastic consumption and uptake by zooplankton, larval herring, and juvenile herring.

Natalie is a biological oceanographer with a particular fondness for the smallest components of marine food webs. Born and raised in Vancouver, Natalie chose to study at the University of British Columbia for her BSc and MSc degrees where she developed her passion for the interdisciplinary field of oceanography. She has worked on projects including describing estuarine plankton dynamics, understanding how zooplankton communities range across productivity regimes, reporting microplastics in marine food webs, and untangling the mystery of juvenile salmon diets.
This is an excellent opportunity for the public to learn more about the potential impacts of microplastics in our area.

The “shroom season” is winding down, and we will move on to other topics soon, but not quite yet!
Here are a few fungi in the genus Tricholomopsis. As far as I know, there are only 2 species in this genus in our area. Both of these usually grow on rotten conifer wood.

and 2. Plums & custard (Tricholomopsis rutilans). From a beach log on the upper shore at Seal Bay. The plum-coloured cap and stipe and creamy-yellow gills complement each other nicely.

Decorated mop (Tricholomopsis decora). This fancy yellow fungus has fibrils and scales on the cap that become dark brown at the centre. Photographed here from the Rosewall Creek trail.
(3)
An older specimen of the decorated mop from the Buttle Lake area. This one was almost ready to keel over and looks quite different from the young version, but the yellow colour and brown fibrils in the centre of the cap are distinctive.

Many of you have likely heard about the discovery of the death cap mushroom in the Comox Valley. Here is some more information from Alison M.:
Re: the confirmation of the death cap Amanita phalloides in Comox, obviously my earlier comment on its not having been seen in the valley should be corrected. It was found in association with Corylus avellana, hazelnut trees from Mack Laing’s orchard, so clearly in keeping with its preference for hardwoods of European origin.
I am assuming that the spores came from an introduced ornamental, with a variety of vectors possibly including deer or squirrels. It would be interesting to know how long the mycelium could have been present without fruiting.

During these days of social distancing it’s heartening to see troops of gregarious fungi gathering in the woods…quite heedless of human disasters.
Here are some groups and clusterings I’ve come across this fall in various locations: Miracle Beach Park, Rosewall Creek trail, Ralph River campground & Shepherd’s creek trail, and Bevan trails (along the upper Puntledge).
[Click a photo to enlarge it.]
1. Pholiota terrestris.
2. Sulphur tuft (Hypholoma fasciculare).
3. Fried chicken (Lyophyllum decastes).
4. Lake’s boletus (Boletus lakeii).
5. Honey mushroom (Armillaria sp.).
6. Xeromphalina sp.
Yellow foot (Craterellus tubaeformis). I think this is right, though this one looks more brightly yellow than any I’ve ever seen.

There are some spectacular displays of “big laughing gym”, also known as “western jumbo gym” (Gymnopilus ventricosus) at Seal Bay Park. You can find it about 3/4 of the way down the main beach trail (on the right) that descends down the ravine. Just before the beach, fork to the right and just past the little bridge (just before the beach) there are several more clumps on the left.
The common name comes from the hallucinogenic properties that some other members of this genus have. However, Gymnopilus ventricosus is actually not psychoactive.
This shroom grows in bright yellow clusters on rotting logs, snags and stumps. Older specimens have a distinctive ring.

(THIS EVENT IS FULL, join the waitlist through our events page) Comox Valley Nature invites you to a special opportunity to learn and connect with K'omoks First Nation storytelling, benefiting the KFN culture department. Pamela Mitchell, Culture Manager for KFN, has created a workshop around the legend of Dzunuk’wa the wild Woman of the Woods. Kwakwak’wakw oral tradition tells of a giantess that lives in dark forests and has thick messy hair, a black face and full red lips.This workshop is a great way to learn about local Indigenous traditions through a hands-on project that creates lasting memories about the K’ómoks First Nation culture. For this project we will be creating a wild woman ornament; you will colour the iconic red lips and face of the wild woman and hand-spin the wool for the crazy wild woman hair. While we work on our ornaments, Pamela will read her version of the wild woman story.This project takes about 1-1.5 hours. Workshop fee is $36 which includes the cost of a supply kit. Proceeds go to the KFN Culture Dept.Register through our CVN events page.https://comoxvalleynaturalist.bc.ca/events/ ...
Drawing on the Salish Sea: A Zoom course in support of the Mitlenatch Island Stewardship Team (MIST)Have you wished that you could keep a nature journal or paint the life around you? During three Zoom sessions you can explore how to quickly capture wildflowers, inter-tidal life and birds You’ll learn how to draw quickly and accurately, starting with simple shapes, then using some refining techniques, which will help you draw with less frustration!You’ll look at materials: papers, pens, and coloured mediums like pencil crayons. Then you’ll jump into watercolours with a simple palette and mixes as well as quick watercolour techniques you can use in the field or at home. All the lessons will be accompanied with downloadable notes.You will finish the course ready to start your own Nature Journal.Zoom recordings will allow you watch the sessions at your convenience during the course and for a month after we wrap up. About Mitlenatch Island:Mitlenatch Island is a small rocky island that sits between Campbell River and Powell River, in the Salish Sea. Cast in the rain shadow of Vancouver Island, its flanks are clad in golden grasses and its meadows host an explosion of spring wildflowers. Anchored where tides rush in from the north and south, rich waters encircling the island teem with fish; intertidal life flourishes and thousands of seabirds nest on cliffs, in rocks, and on open ground. It’s shores provide refuge for mother seals with their pups, and haul out for sea lions in the winter. In recent years Humpbacks have returned to nearby waters, to feed on krill and schooling fish. With so much life, much of it on exposed nesting areas, the island has a special vulnerability. The Mist volunteer wardens are in place for the summer months to welcome people to the island (which is accessible by boat only) and to relate to visitors the natural and human history of the island. For 25 years Alison Watt has spent a week on the island in the summer, as a volunteer warden. Her journals are full of Mitlenatch sketches. She finds it a delight and a privilege to return each year to this jewel of the Salish Sea. MIST is a special organisation which works closely with BC Provincial Parks to ensure that Mitlenatch Island remains a haven for the plants and animals of the Salish Sea.Sign up and donate through www.alisonwatt.ca/drawing-on-the-salish-seaFor more information on Mitlenatch Island visit www.mitlenatch.ca/mitlenatch-island...
Comox Valley Nature invites its members and the public to CVN’s October general meeting, where you can hear the following keynote presentation by our guest speaker: Birdbrains – Smarter than you think- with Sandra Milligan Once dismissed as “birdbrains,” birds are now recognized for their remarkable intelligence. Sandra explores the evolution of our understanding of avian neuroanatomy, focusing on local species. Through engaging stories and videos, Sandra explores how birds solve problems, use tools, express empathy, and communicate with rich vocabulary – inviting you to see these creatures with newfound respect and wonder.Sandra Milligan has been teaching university level biology at North Island College for over twenty years. With graduate degrees in neuroscience, she’s now a generalist, naturalist, and lifelong learner. In Campbell River, she’s a recognized environmental advocate and public educator. Her passion for birding has evolved into a deep interest in avian behaviour and intelligence. Drawing on her neuroanatomy background, Sandra has followed the growing research on bird cognition, confirming what many intuitively felt – birds display an extraordinary range of intelligent behaviours. Sunday, October 25, 2026 at 3 pm in the main hall of Comox United Church, 250 Beach Drive, Comox. Members of the public welcome.This will be an in-person only meeting. We will not record the presentation on this occasion [this is a correction to previous information].As always, there will be a break after the presentation with a chance to meet new people and socialize with old friends. Tea, coffee and treats will be available (by donation).A brief meeting follows. Reports from some of our interest groups and projects are an opportunity for guests to learn more about what we do. ...
It's that time of year! A couple of off leash dogs have been seen romping at the confluence of Morrison Creek and the Puntledge River. Dogs get quite excited to see those big chum. The chum do spawn right at the mouth of the creek, salmon eggs are very sensitive to disturbance so paws, or feet, in the creek kill eggs. Keep your dog on a leash, especially if you do not want a smelly dog! Dogs like to roll in dead fish. Salmon spook, be a quiet calm wildlife paparazzi. ...
Fish Walk!!! ( Well, not really...but don't miss this chance to follow their journey!)Join the Morrison Creek Streamkeepers for a walk along Morrison Creek, starting at its confluence with the Puntledge River in Puntledge Park, to watch salmon spawning after their remarkable journey back from the ocean.
