Salve... Ho trovato un Coprinus s.l. e penzo che gli ho identificata bene come Coprinopsis macrocephala

Radice assente
Velo composto da ife cylindici non ramificanti
Pileipellis cutis da ife rectangolari
Basidia 4-sporate
Spore (12.6)14.6(-16.6)um, ellitice, poro germinativo distinto
su manure

Hello Darniella,
this can be macroceophalus, but does not have to. C. radiata can also become really huge. How wide were the spores? Up to 8,5 µm: radiata; broader, up to 10 µm: macrocephala.
All the best,
Andreas

Hi, Sorry I was very busy the entire week. The spores measure 6.9-8.5 wide (average 7.7), but although I'm not an expert, I am finding it hard to assign it to C. radiata since in the descriptions I've read, the species is minute, with a pileus up to 15mm (usually 10mm). This specimen was 4cm high and the hat 2.0-2.5cm wide. C. macrocephala spores are given as 7.5-8.5 (-10um).


A bit tricky Andreas - do you still retain C. radiata is a better taxon for this finding ? I attach some more images

Hello Darniella,
I believe there is no secure feature to distinguish radiata/macrocephala (ecept sequencing). Spore dimensions and shapes overlap.
And also the size of mushrooms. I have grown on elephant dung radiata, tiny to large mushrooms (stipe up to 150 mm, cap up to 35 mm broad) mixed. In case of doubt, I plead for radiata.
All the best,
Andreas

Andreas, hope you fine.

So I went to the same population early morning, the dung was still there and I could gather more data.

I have measured the diameter of the pileus of all the specimens present and these are the results in mm:
14,13,28, 15,11,30, 7,12,35,20,37,21,12,13,32,18,15,30,10. Range : 7mm-37mm (1StDev: 9 -35 Celsius0


Then I took w specimens: One young and small, the largest pileus (well developped) and a middle one (18mm diameter) and checked the spores of each.

I got these results:

SMall specimen:

I remember very well that the spore data of my first report was from a young specimen, which I chose so that until I arrive home, I can still work on it. I am surprised that there is a discrepancy in spore size between young and fully mature specimens, at least in coprinopsis.

I think now C. macrocephala is most suitable name for this beautiful population.

Hello Darniella,
what an extensive work!
I think you can with good conscience call the find macrocephala.
All the best,
Andreas
