Specimen notes
Public Note:
cap hygrophanous. Stem base with small hyphal bulb. Gills adnate with decurrent tooth. Spore print purple brown. Spores subrhomboid to asymmetric hexagonal. No bluing. Pleurocystidia vesiculose - not chrysocystidia-like. Cheilocystidia lageniform, < 7um diam, < 30um long with abrupt neck (but more uniform in older specimens?!). Spores thin walled. Spores 8.5-9.7(9.1) SD0.4 n=13 x 5.2-6.2(5.7) SD0.3 n=11. Cheilocystidia neck width 2.1-3(2.4) SD0.3 n=12. From NZ taxa then nearest to P. nz but that with different cheilocystidia, no pleurocystidia and different spores (although Egon's original and Peter's NZJB article differ in describing these characters - for Egon cheilocystidia are ampullacous and mucronate and spores are ellipsoidal, for Peter cheilocystidia have poorly differentiated neck and subrhomboidal spores). This does have a look of Egon's PDD71165 = P. nz (but less so the type PDD27132). Egon has a group of PNG taxa in this area but those with chrysocystidia-like pleurocystidia. In Guzman this keys to inquilina (crobula/smithiana/nothofagensis). Guzman is inconsistent in his placement of crobula/inquilina. In the supplement they are in different groups according to spore wall thickness but both treated as thin-walled in original monograph. Clearly there remain different interpretations of this group, especially subrhomboid nature of spores varies with author. So the presence of vesiculose cystidia in this collection and larger sub-rhomboid larger spores leaves some doubt as to where to place it amongst P. nz, phyllogena, inquilina, crobula. Both crobula and inqulina were recorded for NZ by colenso/massee. P. nuciseda recorded for Australia but probably the same. Amongst angular spored taxa: not latispora as that with shorter stem, not phyllogena as that with shorter spores (c.f. Peter J's material which has thicker walled spores than my material?), not acadiensis because spores here much bigger, close to semistriata BFF5 = P.chionophila but that on snow bank mosses. P. nz seems like an appropriate temporary placement. Sequence confirmed as D. nz.
