Clauzadea chondrodes (Stirt.) Clauzade & Cl. Roux 

Description: C. chondrodes is easily mistaken for C. metzleri (described elsewhere). However, the former may be told by the huddled or grouped appearance of the discs. The spores are smaller and clearly ellipsoidal (never ovoid). An additional clue is in the stem of the disc (hypothecium) which narrows to resemble a stalk. Naturally-occurring hard limestone, especially tiered ledges: the Burren, County Clare.

Key Identification Features:

  • Discs in tight groups with ellipsoid spores
  • Disc stem narrowing towards point of contact.
