Observation 168921: Cantharellus tenuithrix Buyck & V. Hofst.

When: 2014-06-12

Collection location: Big Thicket, Polk Co., Texas, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

Found in the Big Sandy Creek Unit of the Big Thicket National Preserve.
Caps up to 6.4 cm across.
“Gills” and stipe white.
Spores ~ 8.2-10.0 X 4.2-5.0 microns, elongate to oblong, many reniform.
Q(range) = 1.76-2.14. Q(ave) = 1.96
These seemed to match the description for C. phasmatis pretty closely. The only hitch is while I didn’t get a strong spore print, they appeared to be whitish rather than “salmon pink”.

Problematic white hymenium?

Bart Buyck’s “Wisconsin Chanterelles Revisited” (2016) p. 353, seems to suggest that Cantharellus tenuithrix has a yellow hymenium throughout development, whether or not the stipe is white. Cantharellus phasmatis and the macroscopically indistinguishable C. deceptivus have a white hymenium in youth. Have I misunderstood something?

No, I don’t remember any bruising but

I don’t recall looking for that characteristic.
I downgraded my vote to reflect the more popular choice.

Did you notice any bruising on the Hymenium when cut?

Patrick….sorry I’ve taken so long to respond.

Just got back from a short trip and needed to check my notes.
Looks like I was mostly influenced by the white hymenium on these which seems to be the most defining characteristic of C. phasmatis. Foltz and Volk call them the “Ghost Chanterelle”. However, due to where I found them, I don’t disagree that C. tenuithrix could be a valid ID also.

Why not Cantharellus tenuithrix

Why aren’t you calling this one Cantharellus tenuithrix?
