spores 7.6-9.1 × 4.3-4.8 ellipsoidal, almost smooth, only faintly rugulose. Hyaline cheilocystidia, often multiseptate appearing like chains. Caulocystidia present, no pleurocystidia. KOH greyish (practically nil) on pileus. Occurs in South Australia with Eucalyptus.

From: Australas. Mycol. 25(1): 25 (2006)

Perhaps seen it after all!

Mike, your fungus looks somewhat like this one, which — unavoidably — I found with Nothofagus.

The molecular analysis places it near C. papaver and an Australian species.
Spores: 8.2-11 × 5.2-6.3 very finely punctate, alkaline nil. I thought mine first was a Pholiota!

I agree also!

When I first saw these I thought it was Cortinarius but on first examination the spores looked to be smooth, I have just taken another look and can confirm that they are extremely finely ornamented, wrinkled instead of warted as in most Cortinarius spores I look at.

The pileipellis structure consists of chains of large cylindrical hyphae with abundant clamp connections and the cheilocystidia form a sterile band and are pyriform to vesiculate, pleurocystidia are absent.

Reactions with alkaline reagents were trivial.

I’m glad you made many good collections here and I look forward to hearing what your thoughts are on many of the interesting finds:)


Agree with Irene

Nice Cortinarius, Mike, but I have never seen this one.
I’m now back in Sweden and try to digest all the generous crops we encountered in the Kaimanawas.
