Drepanoconis nesodaphnes (Berk. & Br.) J. Walker, comb. nov.
== Melampsora nesodaphnes Berk. & Br., Trans. Linn. Soc. London, 2nd Ser., 2:67, 1882.
Galls produced in fruit of host plant, converting the whole fruit into a firm woody gall, 2-3 cm diam. with a dark brown firm interior and an outer, pale fawn, felted powdery layer composed of fungal threads and spores and clusters of host cells. In section, the hyphae are seen to push up in bundles between the plant cells and these tufts form an almost continuous layer over the outside of the gall, and give rise to the spores (Fig. 12).
Hyphae between host cells thin, hyaline, 2 µm diam. giving rise to wider (2-5 µm) branched hyphae in the outer layer. Some of these hyphae give rise to spores whilst others grow on into long (250-300 µm or more) sterile threads, 2-4 µm wide, non-septate or occasionally very sparsely septate, often with a thick wall and very narrow lumen (less than I µm), sometimes with thinner walls, occasionally branched, some with Y-shaped branching at their distal end (Fig. 13). Sporogenous hyphae shorter, 40-50 µm long, appearing to give rise to a terminal spore and then perhaps proliferating sympodially to produce a second spore.
Spores (Figs 14 and 15) hyaline, oval to narrowly pyriform to clavate or obclavate, (13-)15-28(-30) X (6 5-)9-13(-14) µm in the type, (13-)15-33(-35) X (7-)9-12(-13) µm in DAR 40071, a few abnormally large spores to 42 X 18 µm seen (less than I% of the total) and occasionally abnormal X- and Y-shaped spores present. The spores have a finely roughened wall 4-5 µm thick and a thin central lumen 2-3 µm wide (but see below), usually with one central septum, but spores with 2-3(-4) septa also seen, straight or slightly curved, sometimes slightly constricted centrally, with a distinct basal scar I ·5-2 µm diam. which has a central pore and a surrounding thickened refringent ring, often with a short pedicel to 3-4 µm long.
Melampsora nesodaphnes was described by Berkeley and Broome (1882) from a
collection on Beilschmiedia obtusifolia (F. Muell. ex Meissn.) F. Muell. sent to them from Brisbane by F. M. Bailey. Subsequently, R. T. Baker found the same fungus on Cinnamomum oliveri F. M. Bail. in New South Wales.

Seen today. Growing in leaf litter. Cap slimy. Scent pleasant, slightly lemony. (I accidentally touched my face with the mushroom - slight irritation now felt on my face. - I’ve washed my face and hands of course!). Annulus visible and above the ground. Stipe and annulus solid (not hollow). Making spore print.

Apparently 3 differently structured zones on the light pore surface (darker when dried - last photo): surface flat nearest stipe; central band reticulate; to margin, longitudinally striate (‘gilled’) with finer reticulate structures between
