Pezicula eucrita on pine bark
Maren Kamke, 14-11-2016 20:30
Maren KamkeHi again,
another strange discomycete on the inner side of a piece of pine bark between green algae. Up to 0,8 mm, convex, ocher-yellow when young, later brownish red. Short stipitate, bright yellow on the underside. Hymenium up to 100 µm. Ascospores hyalin with sidespores, 0-7-septate, 28-36,5x7-8,5 µm, Asci 8-spored, 88-115 x 16-20 µm, with croziers, strong red porus-reaction with IKl, after KOH-treatment blue. Two types of paraphyses (or hairs?), one with brownish cap, incrustate up to 7 µm wide, the other hyaline clavate up to 3,5 µm wide.
Regards, Maren

Re : Coronellaria ? on pine bark

Hi Maren


If the asci are 4-spored, look for Pezicula eucrita

Re : Coronellaria ? on pine bark
Hi Enrique,
you are right the asci are 4-spored, it is difficult to see. Thanks a lot.
