Specimen notes
Public Note:
cap slippery to the touch, perhaps discolouring orange (orange fibrils on stem - like Letariomyces erythrocephalus), with thick rhizoids. Clustered, with stem and convoluted (secotioid) gills. Hymenium white. Attached to bits of wood. Cap and gills no reaction with NH4OH, FeSO4, KOH. No taste or smell. Spores pale brown/pinkish. Cap a clamped ixocutis with covering of hyphe with yellow extra-cellular pigment. 2-spored. No cystidioid elements seen (certainly not chrysocystidia). Rhizoids with encrusted metuloids?! Could possibly be a contaminationg corticioid. Spores thick walled, with broad germ pore (with cap) and hyaline short apiculus. length=13.9-15.9µm (µ=15.2, σ=0.6), width=7.4-8.2µm (µ=7.6, σ=0.2), Q=1.8-2.2µm (µ=2.0, σ=0.1), n=11. If Egon's Nivatogastrium lignicola were 2spored then it would be close, and suspect all NZ Nivatogastriums are Leratiomyces. The type of Nivatogastrium (nubigenum) is a secotioid pholiota. The remaining three (apart from W USA N. 'wrightii') are Egon's from NZ. N. nubigenum is variously described with and without a germ pore ('very narrow' in protologue) , all of Egon's taxa have chrysocystidia. Possible that N. nubigenum and N. baylissianum are related - as snowbank fungi on twigs (see comments by Smith in his monograph on Pholiota) [2010] immature collection
