Notes. The material studied shows a wide variability in the size of the sporophores, ranging from 0.3 to 1.5 mm in total height, even within a single collection (e.g. Lado 26135), unlike what is reported in the literature, varying from 1-1.5 mm ( Lado & Pando 1997, Nannenga-Bremekamp 1991, Poulain et al. 2011). Besides, Lado 25371, 24634, and 25192 collections have comparatively paler capillitium spirals and yellowish spores.
