Article: Dennis, R.W.G. (1961). Some inoperculate Discomycetes from New Zealand. Kew Bulletin 15(2): 293-320.
Description: Spores 13-19 x 3.5-4 ยต, nonseptate, asci up to 165 x 99, I-.
Notes: In Kew Bull. 9: 319 (1954) I treated this as a synonym of C. citrina (Fr.) Regél. but
examination of the abundant New Zealand material leads me to Quard it as separable by its
more elongated nonseptate ascospores. It differs from Helotium conscriptum (Karst.) Karst.
in its sessile apothecia as well as in its calycelloid excipulum.
