Q = (1.7) 2.2 - 3 (3.3) ; N = 15
Me = 6.3 × 2.5 µm ; Qe = 2.6


KOH extractable pigment data forthcoming.

The ITS region fully coincides with an unpublished sequence of "Ionomidotis" olivascens by K, Pärtel (KL325). As long as there is no sequence from the type, we may safely say I. olivascens. If there are morphological differences to Ameghiniella I cannot say. 

KL325 is CUP MJ1032 from Jamaica fide Kadri and was acknowledged by Zhuang. I tend to place this species in Ameghiniella which has lkewise ionomidotic apothecia.
