Observation 296130: Crinipellis zonata (Peck) Sacc.

Notes:
Concentric rings on cap, white gills, dark stipe with herringbone-like stiples. Stereo microscopy confirms dense hair on cap of dried specimen (required for Crinipellis). Spores do not show any sign of amyloid ornamentation in either Lugols or Melzers (a characteristic of Melanoleuca per Kuo). Note one branched hyphae which ‘could’ be a branched basidia (a characteristic of Crinipellis per Kuo), but this seems unlikely as all other basidia seem much smaller.

…then Melanoleuca.

Thanks for sharing your experience. I was not aware of the other smaller species.

Crinipellis or Melanoleuca? It’s coming to me in the mail.

Thanks heelsplitter, I will take your experience for

Based on range and size and how robust this is

There are only 4 Crinipellis species reported from North America AFAIK. Crinipellis zonata seems to be the largest and most robust and I’m not sure if C. campanella even grows as far south as Maryland. Either way, it also seems to be less robust than C. zonata. C. setipes and C. piceae are both much smaller than this. It could be that there are multiple species going as C. zonata, but in my experience collecting what I call C. zonata, it seems to be a fairly variable species and this is well within the typical variation.

Okay, Django

Would you look at what is identified as Crinipellis on MO? There is such a range that I doubt this can be reduced to species. But I like the name and agree the cap has concentric zones. What else makes you so sure?

Thanks Pulk and heelsplitter!

No wonder I didn’t recognize. This is my first time seeing it. Thanks!
