A fourth site for Cvphelium notarisil has been found in the Picos de la Higuera in La Pedriza del Manzanares in the Sierra de Guadarama, Comunidad de Madrid. Ihe , which is rare in many parts of Europe, occurred on a decorticate Pinus stump amongst granite boulders. Photographs of the habitat, and photomicrographs and line drawings of the ascospores, are included. At- tention is also drawn to some differences in published details ofthe number of celís in the ascospores and their dimensions.
