Article: Stalpers, J.A.; Buchanan, P.K. (1991). Type studies of the species of Pellicularia and Peniophora described by G.H. Cunningham. New Zealand Journal of Botany 29(3): 331-340 (http://www.rsnz.org/publish/abstracts.php).
Description: Subicular hyphae hyaline to yellowish, thin- to thick walled (up to 2.5 µm), finely asperulate, 10-18 µm wide. Subhymenial hyphae hyaline, thin-walled, 6-12 µm wide, cyanophilous. Basidia collapsed. Spores hyaline, smooth, ovoid from above, navicular in side view, 5.5-7.5 x 2.8-3.5 x 3-4 µm, somewhat thick-walled with prominent apiculus.
Notes: The species is indistinguishable from Botryobasidum pruinatum. The spore size is much smaller than Cunningham's (1953) measurements (8-11 x 3.5-4.5 µm). The basal hyphae are somewhat less thick-walled, paler and more finely asperulate than typical European'specimens, but these differences are herein considered to be within the natural variation of the species.

Article: Cunningham, G.H. (1953). Thelephoraceae of New Zealand. Part II: the genus Pellicularia. Transactions of the Royal Society of New Zealand 81(3): 321-328.
Description: Hymenophore annual, loosely attached, lifting, arachnoid-mucedinoid, forming linear areas to 24 x 3 cm.; surface cream, drying pallid ochre, even; margin thinning out, cream, arachnoid. Context composed of a few large repent hyphae to 16 µ diameter, wall 0.5-1 µ thick, delicately and finely verruculose-scabrid, sparsely branched, septate, without clamp connections, fertile hyphae vertical, bearing one to three whorls of branchlets carrying basidia and paraphyses. Basidia cylindrical or subclavate, 16-22 x 6-9 µ, bearing 4-6 spores on short sterigmata 3-4 µ long. Spores fusiform or navicular, ends usually bluntly acuminate, apiculate, 8-11 x 3.5-4.5 µ, smooth, hyaline.
Habitat: HABITAT. Effused on bark or decorticated decaying wood.
Distribution: DISTRIBUTION. New Zealand.
Notes: Of the species without clamp connections this may be identified readily by the large diameter repent hyphae, walls of which and of the fertile branches are covered with closely arranged verrucae, appearing scabrid. Basidia are carried on short branchlets arranged in whorls on main vertical branches. Basidia usually bear six spores, though a few carry four.
