Observation 158389: Panaeolus sect. Verricuspora Gerhardt
When: 2014-01-16
Who: Byrain

Notes: Found in the dunes growing from grass.

Spores fine asperulate, wall 1-2 µm wide
Spore range = 14 – 17 (18) x 9 – 10 (11) µ
Spore average = 15.45 × 9.65 µ
Q range = 1.5 – 1.78
Q average = 1.61
20 spored measured in KOH.

Cheilocystidia range = 23 – 46 (55) x (6) 7 – 11 × 4 – 7 (9) µ
Cheilocystidia average = 33.35 × 8.65 × 5.2 µ
20 cheilocystidia measured in KOH.
Caulocystidia range = (12) 16 – 53 (63) x 6 – 17 × 6 – 9 (10) µ
Caulocystidia average = 31.85 × 10,85 × 8 µ
20 caulocystidia measured in H2O.

Sulphidia measured = 14×10, 15×11, 15×11, 15×13, 17×10, 23×13, 25×12, 31×8 µ
Epicutis cells measured = 18×17, 20×19, 21×17, 22×22, 23, 25×21, 28×26, 30×26, 36, 40 µ
Basidia measured = 27×11, 29×12, 30×11, 31×12, 33×11 µ
4-spored, clamps observed on the gills and stem.

Gerhardt only lists two species in sect. Verricuspora, since this has sulphidia & is not growing in Africa from dung it seems to be neither P. olivaceus or P. africanus.

Seems to be..

a 99% match with many understudied Panaeolus collections…

Also this Uncultured Pleosporales clone.
https://www.ncbi.nlm.nih.gov/...

Whoever submitted that must of been really high…

On the other hand this does not seem to match this German Panaeolus olivaceus collection indicating that this is indeed new to science and that the sulphidia could be a good way to differentiate it.

Edit: Or maybe its not matching because its the wrong kind of sequence?
