Article: Gadgil, P.D. (in association with Dick, M.A.; Hood, I.A.; Pennycook, S.R.) (2005). Fungi on trees and shrubs in New Zealand. Fungi of New Zealand. Ngā Harore o Aotearoa 4: xi + 437 p. Hong Kong: Fungal Diversity Press.
Description: Type: Mycorrhizal Fungi; Description: Basidiomata epigeous to subepigeous, subglobose to pyriform but very variable in shape and size, dirty white to ochraceous, becoming brown, 30–200 mm high, with a prominent rooting base; peridium composed of a single layer, thin, membranous, breaking away irregularly from the apex. Gleba divided into polygonal or lenticular chambers by persistent tramal plates; chambers filled with a powdery, ochraceous to brown mass of basidiospores. Basidiospores globose, 0-septate, 7–12 μm in diameter, densely covered with spines, smoky grey.
Distribution: Distribution: Areas affected by geothermal activity in Bay of Plenty, Taupo.; 1st Record: Chu-Chou & Grace (1983b).
Notes: Notes: Recent work (Moyersoen et al. 2003) has shown that P. tinctorius may not be present in New Zealand. These authors showed that on the basis of rDNA internal transcribed spacer (ITS) sequence analysis and spore morphology, the New Zealand collections fell into three phylogenetic groups that have been previously proposed as putative species associated with Eucalyptus spp. in Australia.
