Octospora on Bryum rubens agg.
Georges Greiff, 07-12-2018 20:28
Hi there,

I wanted to check this recent find of possible Octospora coccinea found on the moss Bryum rubens.

Apothecia orange, < 2.5mm, margins not differentiated. Asci 8-spored, 127.40 x 16.12. Paraphyses 4.0 wide, 5.2 at bulging tips, orange pigment. Ascospores hyaline, guttulate, 23.50 x 11.20 approx, measured in water.

Thanks,

Georges

Hi Georges,
I think your find is Octospora cf. gemmicola. O. coccinea should have longer spores with 2 larger and 2 smaller guttules. Best regards, Zuzana

Re : Octospora on Bryum rubens agg.

Hola Georges.


No, yo creo que no es O. coccinea. Esta especie tiene esporas más largas y más estrechas que su recolecta.


También hay que fijarse en las gútulas del interior, que normalmente son 2 más grandes y 2 más pequeñas hacia los extremos.


Su recolecta podría ser cercana a Octospora gemmicola Benkert.


Adjunto foto de esporas de O. coccinea.


Saludos

Re : Octospora on Bryum rubens agg.
Thanks both. Looks good for O. gemmicola - I did not see very conspicuous margins but perhaps the collection was too young. This might be a new record for Britain so I will send it for confirmation.

Thanks again
