- Notes: Ear to fan-shaped, uniformly thick (ca. 1 cm), smooth, crumbly, reddish brown (pale in shaded parts). Can be confused with Cribrochalina vasculum (Lamarck, 1814), which is tougher and rather more elastic. Also, with Petrosia weinbergi, with which it shares a wide range size of oxea spicules, but lack the small toxa, is more crispy in consistency, and is greenish.
