Observation 150024: Cantharellus roseocanus (Redhead, Norvell & Danell) Redhead, Norvell & Moncalvo
When: 2013-10-26
No herbarium specimen

Notes: squat stature (very short-stemmed), bright yellow hymenium slightly pinkish (difficult to capture on camera), and highly intervenose gills separate it from C. formosus

Proposed Names

-6% (6)
Recognized by sight: pink HYMENIUM is characteristic of formosus; pink bloom on CAP = roseocanus. many western chanterelle sp. show intervenous ridges. morphology of fruit bodes variable in all species.

I vote proposals down that could be right just because that really deserves more info. When I have left just a comment the observer will often ignore it, but if I even suggest they could be wrong with a vote they’re more likely to be engaged and provide the useful data to silence any skeptics. Of course sometimes it has the opposite response…

of the two ways in which the voting system is and must be used, regardless of how it was intended to function.

1: to express the likelihood of a given name being the ID of the fungus pictured

2: to express the extent to which a given observation deserves to have a name marqueed in big bold italics at the top of the observation page, and thus scraped as such by Google Images, given the amount of information present.

I am often voting down names not because they definitely aren’t the thing pictured, but because the thing pictured definitely shouldn’t be called anything definitively without more information.

as to pink hymeniums in golden chanterelles …

I think it safe to say that Christian’s field experience in the PNW is less than that of, say, the PNW key council members. This is what they had to say about pink coloration in roseocanus and formosus:

REMARKS Unlike the Pacific golden chanterelle, the rainbow chanterelle has a smooth cap that lacks closely appressed scales even when young, exhibits no immediate yellow staining when bruised, and has a darker spore print. The bright orange yellow ridges of the rainbow chanterelle lack a pinkish cast, so that any pink coloration is generally restricted to the outer cap margin. The intense pinkish coloration found in certain young or dry Pacific golden chanterelles [aka formosus DV], on the other hand, is found only on the hymenium.

Neither chanterelle description even mentions intervenous gills for either species. They happen broadly and randomly across chanterelle species.

In other words, calling a merely intervenous, somewhat stocky (but in fact rather blown out and frilly in this photo) PINK GILLED golden chanterelle roseocanus is fully “as if!” worthy. or whatever is the lowest designation that you come up with here.

I don’t care who is making a post. the evidence should be there for all to see and confirm. Don’t even get me started on the dataless posts without even a photo!
Those are just grocery lists.

maybe not the venue for this

but why not drop that “as if” altogether, Nathan? seems as tho it is mostly just used in a, shall we say, snide manner.

we’ve all moved on from our Valley Girl days, I think?

not sure what you mean by “can’t be used.” as long as it can be copied, it can be used.

it’s the ID in question, not the art.

if someone is searching specifically for a good example of roseocanus (or formosus, for that matter) this ain’t it.

Since the “As If!” votes prevent either of those names being used, I’ve added the genus level id so this can get shared out. Personally, I’m happy to take Christian’s work that is was C. roseocanus, but I agree with Debbie that there isn’t enough concrete evidence to clearly support that name over C. formosus.

I feel I need to note that this sort of use of “As If!” is not the intention of the current naming system and it prevents useful photos like this from getting shared with others. If you think it could well be C. roseocanus, then you should probably vote “Promising” or maybe “Could Be”.

Christian saying “As If!” to C. formosus is presumably based on his long experience with both species and other information that he has about the collection.

uh huh.

all I’m saying is that what you show here is not obviously roseocanus, certainly not with a pink hymenium or by using the broadly found character of intervenous gills to make that ID.

not every member of a species looks the same. but you already know that.

a photo search of what…

Debbie, you should know better than to assume that photos online are correctly identified. If you really need to, go ahead and propose Cantharellus sp. The stature on this is completely unlike any C. formosus I have ever seen.

just did a photo search on western cantharellus hymenium

formosus, californicus and cascadensis all can show intervenous gills. roseocanus sometimes shows internvenous gills (or not). it is apparently a variable in most if not all of our western chanterelle species.

your photo shows insufficient detail to make a good ID, but the hymenium color alone sez formosus to me, and pinkish cast to the gills is far more typical for that species. they are not always thin and elongated, either.

The ‘gills’ of C. roseocanus can have a pinkish cast, but are not predominantly pink. Usually yellow-orange in my experience. Brighter than other north-coastal chanterelles.
Yes, morphology is variable, but you still have to take it into account. The squat stature and strongly intervenose ‘messy’ gills are much more like C. roseocanus.
