Pulvinula sp. from Debrecen (Hungary)
Zsolt Sütö, 02-09-2018 18:37
Hi everybody !
Habitat: Debrecen, Hungary, landscaped area (Debrecen's great
forest, clinic area (I've found it several times in the same place: 2018.06.15; 2018. 06.20;2018.08.27)

Apothecium: their size is 2-5 mm, color is orange, slightly brown


Substrate: between smooth soil and moss, I did not find the carbonized tree in the soil


Spore: the smooth spores are spherical and contain many larger drops of oil, the size of spores: (15,0) 15,9 (16,8) x (15,7) 16,7 (17,7)


Ascus: 8 spores, the size of ascus 240 - 270 x 20-25, I could not observe operculum, the bottom of the ascas is mostly branched. The potassium iodide iodine reaction is negative.


Paraphysis: size, have only latitude data: 1,9-2,2, thin with their ends curved, thin with their ends curved (size: 0,7-1,2).


Here is the end of my science. This species is a Pulvinula (I think). Maybe P. convexella, but I'm insecure (I'm amateur). Other opinion?.


Thank you in advance.

Re : Pulvinula sp. from Debrecen (Hungary)
Ascospores are somewhat too small for P. convexella.
Pulvinula is a hard genus...

Re : Pulvinula sp. from Debrecen (Hungary)
Dear Nicolas, thanks!

Then maybe I let it go.... I also wondered about two other species: Pulvinula carbonaria and Pulvinula costellatio. The size of the spores is closer. I excluded the first because the shape of the bottom of the ascus is different. I found little information about P. costellati


It's too hard for me. As amateur I am satisfied with the genus. :-)


thanks for the reply
