Specimen notes
Public Note:
https://inaturalist.nz/observations/2753781 [WD] Small funnel shaped fungi growing in clusters on rotting stump. Cap dark brown with a fibrous surface growing up to 2.5 cm in diameter and 3.5 cm in height. Gills are descending, pale yellow with a darker edge when young becoming mustard with age. Stipe creamy-tan, central to off-centre. Remnant mature coastal broadleaf forest. [JAC] Maybe the same as your previous Gerronema? That now has a tag name of Gerronema sp. 'Howick (PDD105913)' with a couple of collections.[WD] Possibly different. I observed the spores of Gerronema sp. "Howick" as more oblong. The spores of this species are more subglobose. This is also a smaller species. I have seen it previously but never had good images and it never grows very large. The yellow gill colour is also characteristic. [JAC] Gerronema 'Pororari' has yellowish gills, sometimes, but a fibrous cap and not so infundibuliform. Hydropus/Clitocybula with amyloid spores. There's still some Stevenson species in this group without recent collections. This is worth a specimen. Incidentally those brown cap cystidia are the 'hydropoid vesicles' characteristic of many Gerronema/Hydropus ( Porotheliaceae). [WD] Spores not amyloid in Lugol's iodine. Can forward. [JAC] dark gill edge is brown vesicles. Spores subglobose so not sure this is poroarri or howick. Spores length=4.5-5.3µm (µ=4.7, σ=0.24), width=3.3-4.7µm (µ=3.9, σ=0.45), Q=1.0-1.6µm (µ=1.25, σ=0.16), n=10. Sequence in core Trogia group. Same as PDD81522
