Lamprospora?
Henk-Jan van der Kolk, 16-01-2014 17:59
Hello all,

This week I found a orange discomycete with the moss Campylopus pyriformis, of which I think it possibly is a Lamprospora. However, following several keys I can not find a good match. Octospora wrightii comes close, but grows on different host/substrate and has slightly elipsoid ascospores.

Description:
Substrate: On acid soil with Campylopus pyriformis
Fruit bodies: Discs orange, about 1-1.5mm in diameter, with margin
Asci: about 200-260x15-20um, containing 8 spores in one row
Spores: 13-15 um diameter, circular, with fine warts (in width and heighth <1um)

 Regards, Henk-Jan

Re : Lamprospora?
Dear Henk-Jan,
To see correctly the spore ornamentation, it would be useful (necessary) to show the spores outside the asci and mounted in cotton blue reagent.

Re : Lamprospora?
Hello Henk- Jan,
if like from Nicolas suggested with cotton blue mounted of ripe spores a net is to be seen, I would regard the kind as Lamprospora carbonicola.
Greetings Peter.

Re : Lamprospora?
Hello Henk-Jan,

your find is very interesting. It seems to bee a Lamprospora but the only known species known to parasite on Campylopus pyriformis is L. campylopodis. In contrast to your collection L. campylopodis has a spore ornamentation of very prominent ridges which form a large meshed reticulum. So your specimen seems not to be L. campylopodis.
I also would very much like to have a better image of the spore ornamentation of your collection to make another guess. Did you investigated more than one apothecium to exclude abnormal spores?

With best wishes

Jan

Re : Lamprospora?
L'ornementation semble être formée par des verrues.
Voir L. lubiscensis mais la mousse ne convient guère  (normalement, Pottia heimii)

Re : Lamprospora?
Adio Jan Eckstein, why not Lamprospora ecksteinii ?!  :)
Problem of mosses ?

Lampro aren't my speciality but I couldn't help myself !  :)))
