Re : rustroemia??

Hi Ismail


Rutstroemia carbonicola Svrcek might be a possibility, but it is said with ascospores (15—) 16—21 X 5.5—7 um. Are you sure of your measurements?

Re : rustroemia??

You are Svrcek's description here  http://www.czechmycology.org/_cm/CM334.pdf


Please, you should take spore measurements only on free ascospores in the water.


But I'd like to know Baral's opinion


Regards
