Records of this species from New Zealand (Gagdil 2005) on Viburnum lantata and V. carlesii are quite unclear. The collections concerned have been examined (PDD 19826, 19843, 1985), but sufficient fructification for a final identification has not been found. Superficial hyphae with solitary conidiophores found on “V. lantana” are not in accordance with P. varia. The host identity is also uncertain (short petioles do not coincide with V. lantana but they are rather in favour of V. burejaeticum.
