Neocampanella blastanos

Neocampanella blastanos (Boidin & Gilles) Nakasone, Hibbett & Goranova 2009, in Nakasone et al., Botany 87(9): 877 (2009).

Basionym: Dentocorticium blastanos Boidin & Gilles [as 'blastonos'] 1998

Diagnosis: Basidiome resupinate, appressed, widely effuse, beginning as small circular patches, coalescing, up to 70 — 30 mm, thin, up to 180 µm thick, membranous, soft, white, light yellow (4A3), greyish yellow (4B3), orange white (5A2), or pale orange (5A3), smooth, porulose, or subpulverulent, lacking cracks, not reacting to KOH; margin more or less distinct, abrupt or rapidly thinning out. Hyphal system monomitic, generative hyphae with clamp connections. Subicular hyphae 2-3 µm diam, nodose septate, walls thin, hyaline, typically encrusted with a thin layer of hyaline crystals. Subhymenium not observed. Hymenium a dense palisade of dendrohyphidia, cystidia, and basidia. Dendrohyphidia simple or highly branched, sometimes knobby, 20-45 µm long, 1-2.5 µm diam, with a basal clamp connection, walls thin, hyaline, encrusted with a thin layer of adherent, hyaline crystalline material. Cystidia cylindrical to subfusiform, capitate, sometimes slightly enlarged at the base, 35-60 — 5-9 µm, apex 4-10 µm diam, with a basal clamp connection, walls thin, hyaline, smooth. Basidia collapsing soon after maturity, cylindrical, sometimes slightly enlarged at the base, occasionally with lateral knobs, 30-35 — 6-7 µm, with a basal clamp, walls thin, hyaline, smooth, 2-sterigmate. Basidiospores often in clusters, pyriform to ellipsoid, tapering slightly toward prominent, blunt apiculus, 11.5-15 — 5.5-7 µm, Q = 2.0-2.1, sometimes developing a short germination peg, walls thin, hyaline, smooth, acyanophilous, not reacting in Melzer's reagent. Habitat: on wood and bark of small hardwood twigs.

Figure 1. Phylogenetic placement of Neocampanellss blastanos based on maximum likelihood (ML) and maximum parsimony (MP) analyses of nuclear large subunit ribosomal RNA gene sequences. This is the optimal tree obtained with ML. Filled dots on branches indicate groups in the strict consensus of the 706 equally most parsimonious trees. The number along branches before slash marks (/) are frequencies from 100 ML bootstrap analyses. The number after slash marks are frequencies from 1000 bootstrapped MP analyses. Bootstrap frequencies below 70% are not shown. Scale bar units represent the number of substitutions per site. (Naksone et al., 2009).
