Coprotus granuliformis 140112 60
Miguel Ángel Ribes, 12-03-2014 20:57
Miguel Ãngel RibesGood night

I had this collection like C. granuliformis, but it hasn't "paraphyses with strongly inflate apices" as said by Franceso Doveri in Fungi Fimicoli Italici, and apos are very, very small, (80-)90-130(-140) µm, globose to subesferich at first, pulvinate at maturity. Spores are very small for C. leucopocillum; and C. trichosurus is a New Zealand species.

Asci clavate to saciforme, rounded at apex, with a short walk and lobed, with croziers, irregularly biseriate of ( 36.8 -) 37.6 - 53.1 ( -66.2 ) x ( 12.7 - ) 14.2 - 19.8 (-20.7 ) um, N = 17, Me = 46.2 x 16.5 µm. Ellipsoidal, hyaline, smooth ascospores, rounded at the ends, ( 10.2 -) 11.1 - 12.4 ( -12.8 ) x (6.2 -) 6.6 - 7.8 (-8.1 ) um, Q = (1.4 -) 1.5-1.8 (-1.9 ), N = 61 , Me = 11.7 x 7.2 µm ; Qe = 1.6 . Paraphyses filiform, septate, relatively thick-walled, slightly constricted in the septa, without pigment or lipid content, exceeding the height of the asci, not forked, straight, (1,3 -) 1.8-2 , 8 (-3.3 ) um, Me = 2.3 µm wide at the penultimate cell and thickened up to (2.2 -) 2.4-4.3 (-5.0 ) um, Me = 3.3 µm at the apex. Undifferentiated medullary excipulum. Ectal excipulum of globular-angular texture with cells (6.2 -) 7.4 - 11.1 (-13.1 ) x ( 4.9 -) 5.7 - 9.3 (-10.8 ) um , Q = (1.0 -) 1.1-1.5 (-1.9 ), N = 111 , Me = 9.1 x 7.4 µm ; Qe = 1.3.

Thank you in advance.

Re : Coprotus granuliformis 140112 60
Dear Miguel,

I think you should compare with Coprotus trichosurus.
Why should this species not grow in Europe?
Ann Bell and J.W.Kimbrough described it, which is closely to C. granuliformis, in 1973.
It's a very small species with apothecia from 125 - 175 µm!
Only your ascospores seems to be a little bit too broad.

Re : Coprotus granuliformis 140112 60
Wooooow

Dear Norbert

The nearest species for my collection is, as you say, C. trichosurus (I had read that paper), but I am affraid to asigned that name, because it is from New Zealand and were found on fecal pellets of an opossum. Really macro and micro fits more with C. trichosurus than C. granuliformis nor breviascus.

I do not know what to do, perhaps is it possible to ask Ann Bell or J.W.Kimbrough?

Thank you.

Hello Miguel and Norbert.

Very
interesting specie, but it is difficult to decide. 
F.Doveri indicates the top of paraphyses up to maximum 5 microns. We also find little C.granuliformis without pigment in the paraphyses.

Thank you Miguel and to Norbert for this paper.
Michel.

Re : Coprotus granuliformis 140112 60
Hello Michel

Small collections of C. granuliformis without pigment in the paraphyses that you find, has strongly inflate apices and normal spore size for C. granuliformis?

Has anyone the mail of Ann Bell or J.W.Kimbrough?

Thank you.
Michel Delpont, 14-03-2014 14:06

Re : Coprotus granuliformis 140112 60
Yes, no differences in size to the spores and paraphyses.
Sorry, I do not have the adesses you ask.

Michel.
