DISTRIBUTION: New Zealand.
In an earlier paper (1954, p. 290) I referred the species to C. radiosum Fr. As J. Boidin has pointed out it differs from this species in the larger nonamyloid spores and presence of clamp connections.
= Aleurodiscus amylaceus (Bourd. & Galz.) D. P. Rogers & H. S. Jacks.
Subicular hyphae thin- to slightly thick-walled, 2.5-4 µm wide, with clamps. Gloeocystidia hyaline, with resinous contents, clavate to cylindrical, up to 15 µm wide, apically with up to three monihoid swellings, not protruding. Young basidia clavate, up to 55 X 6-8 µm. Basidia clavate to suburniform, often with 1-2 constrictions, 45-70 X 10-12 (apically) X 10-14 (widest inflation) X 5.5-8 (narrowest constriction) X 4-6 (basal attachment) µm, with 2-4 sterigmata, up to 9 µm long. Hyphidia rare, simple or very rarely branched, 2.5-3.5 µm wide. Spores hyaline, more or less thin-walled, ovoid to broadly ellipsoid, 8.5-10 X 6.5-7.5 µm, amyloid, distinctly apiculate.
