Mollisia K+ yellow
Jenny Seawright, 04-03-2015 11:26
Jenny SeawrightHello all,

Sorry for poor images but I found this Mollisis with grey apothecia and a dark subiculum on Ulex europeaus. Too immature for spores but I remembered Andreas saying in a post on a different forum that Mollisia fusca gave a K+ yellow reaction.

Is the K+ yellow from my specimen sufficient for identification or are there other Mollisia's with a similar reaction?

With regards,
Jenny

Re : Mollisia K+ yellow

Dear Jenny,


 


no chance, sorry!


About 25% of all Mollisia species have a yellow KOH reaction.


The reaction you show here is quite weak, what would exclude M. fusca - if the colours are correct.


On Ulex there are several of Mollisia species, some confined to ulex, some lurivorous.


 


best regards,


Andreas

Re : Mollisia K+ yellow
Thanks for the clarification Andreas, I thought that might be the case. The K+ reaction was stronger than shown in the image, but difficult to quantify how strong.

Knew I shouldn't have ventured into Mollisia's!!

With regards,
Jenny
