I am working on another new basidiomycete, this time a clear pluteus for its free gills (distant from the stipe), rose-light brown spore print and lack of veil, ring and volva. The light lemon-yellow colours of the stipe and the subspherical spores indicates a P. romelii, but the cream with a very faint hue of yellow colour of the pileus is quite off for the species (P. romelli is caramel to cinnamon brown). So here I am discussing this fungus with you.
Basidia oblongish-subclavate, sometimes flexuous, predominantly 2-spored, rarely 3-spored, up to 35um long
Cheilocystidia are large, lageniform to broad utriform (prone to correction!)
Pleurocystidia present, similar to the cheilocystidia, perhaps a bit smaller
Spores subspherical (some looks spherical) to globose-ovate, Me = 7.1 × 6.3 µm; Qe = 1.1; Ve = 152 µm3; 5.9) 6.2 - 8.1 (8.6) × (5.2) 5.7 - 7.1 (7.7) µm (n=33). In lugol's iodine they showed a dextrinoid reaction, while in Cotton Blue (with lactic acid), the spores collapsed inwards.
They were growing from leaf/twig litter of Eucalyptus plantation. I had in mind Pluteus romellii s.l. and Pluteus boudieri P.D. Orton 1960
I am aware by the work of : Holarctic Species in the Pluteus romellii Clade. Five New Species Described and Old Names Reassessed [ https://www.mdpi.com/2309-608X/8/8/773 ] but all their described species do not show this pale pileus. P. boudieri is my best match so far.
