Coleofasciculus chthonoplastes (Thuret ex Gomont) M. Siegesmund et al.

Laguna madre, Kenedy Ranch, sands flats (15_3). Overgrown mat in the plastic tray (3 weeks). Lyngbya sp. took 50% on the surface, 30% occupied by Coleofasciculus sp. The rest 20% have taken by other cyanos. This mat was thinnest observed (less than 0.5 mm). In second layer from surface Coleofasciculus sp. was a dominant form.

Laguna madre, Kenedy Ranch, sands flats (15_2). Mat material which have been stored in the fridge for 3 weeks. Lyngbya sp. were a dominant on the surface. Coleofasciculus ssp. were dominated inside the mat (1mm deep), with Lyngbya sp. in the rare occurance.

Laguna madre, Kenedy Ranch, sands flats (15_1). Mat material from the fridge. Lyngbya sp. were a dominant on the surface. On the 1 mm deep Coleofasciculus chthonoplastes were dominant. Note:representatives of Coleofasciculus ssp. were in the huge abundance in the 1mm deep layer.

Laguna madre, Kenedy Ranch, sands flats (16_3). Mat material. Lyngbya sp. were a dominant on the surface. Lyngbya sp. is dominant with 50% of occurrence in the sample, Synechococcus sp. took ~40%, the rest of the species - 10%, in the 1 mm deep. Note:representatives of Coleofasciculus ssp. were in the little abundance to compare with the another samples.

Laguna madre, Kenedy Ranch, sands flats (16_2). Preserved material (Formaldehyde). Lyngbya sp. is dominant with 90% of occurrence in the sample, the rest of the species took ~10%.
