Specimens growing on moss and other debris of a wall in the field. Initially I thought it was a species of the genus Mycobilimbia, which long ago had found, but the microscopy revealed spores with a high number of septa, and in that genus the number of septa is less than or equal to three. The high number of septa, the shape of the spores and the existence of a gelatinous and amyloid sheet envolving the asci undoubtedly place this specimen in the genus Bilimbia. Their characteristics are consistent with those described in references 1 and 2 for the species Bilimbia sabuletorum and with the images presented in reference 2. There is a macroscopically similar species, Bacidia bagliettoana, but its spores are different (acicular form and bigger). Average dimensions of the spores: Me = 31.8 x 6.6 µm ; Qe = 5 (N=30).
