No specimen available

Following observation 209084, continuing the search to my files I found another specimen of Polysporina simplex. This is growin on the sliceous stones of a fence.
According to the British Flora the photobiont of Polysporina belongs to the genus Myrmecia (see the attached photos). This is similar to Trebouxia with smaller chorhoplast and central core. It is the photobiont of some species in the following genera, among others: Bacidia, Catillaria, Dermatocarpon, Lecidea, Verrucaria.
Each ascus contains between one and two hundred of spores, which in the case of P. simplex have dimensions in the ranges: 3- 5(5.5) x 1-1.5 um.


Microscopy: Sections;
Microscopy: Sections-close up, alga and an ascus full of spores.
