Foliose, strictly speaking

Dirinaria look crustose, but if you’re very careful you can remove it from the substrate with the lower cortex intact. Crocynia additionally should be distinctly “cottony”, since it lacks both upper and lower cortex. Dirinaria, incidentally_ are excellent test subjects to calibrate your UV light: they fluoresce strongly ice-blue at 350 nm, but do not (or hardly) fluoresce in the more common 370+ nm wavelengths.
