A beautiful clump of Coprinellus saccharinus (or micaceus) under Ceratonia siliqua (Carob tree) in succession (on clump completely over, one old and blackened, one drying up and this last clump just in time for photographing and collecting some specimens.
Veil white and tiny made of globose elements (sometimes with a tail like a balloon).
C. micaceus is another option (maybe better for the mitriform spores ?) but the stipe was glabrous almost completely without caulocystidia but maybe wiped during handling or from old age.
Spore dimensions:
(8.4) 8.9 - 10.3 (10.6) × (5) 5.2 - 6.1 (6.3) µm
Q = (1.5) 1.6 - 1.8 (2) ; N = 31
Me = 9.5 × 5.7 µm; Qe = 1.7
