Description: Pileus -35 mm diam., campanulate to broadly
umbonate; straw-yellow to lemon-yellow; conspicuously innate-fibrillose, smooth

when young turning yellow-brown, edge con colorous. Stipe -30 x -5 mm, cylindrical,
base clavate to bulbous, submarginate; yellow, pruinose for whole length; veil
remnants absent, dry, becoming hollow, single in groups. Context yellow to yellow-green,
turning light orange. Odour spermatic.
Spores 8-10 x 5-6 µm, irregular angular,
knobs not pronounced, brown. Basidia 25-33 x 6-7 µm, 4-spored. Cheilo- and pleurocystidia
60-80 x 15-20 µm, thick-walled, encrusted or not, yellow-brown plasmatic pigment
in KOH, fusoid. Caulocystidia 50-90 x 10-18 µm, cylindrical to lageniform, mostly
thin-walled, occasionally encrusted. Cuticle a cutis of cylindrical hyphae (3-10
µm diam.), membranes encrusted with yellowish pigment. Clamp connections present.

Notes: The yellow colour and the habitat are distinctive
for this rare species. To my knowledge there is no other yellow Astrosporina
in Australasia.
