Name

Diagnosis

Gymnopus ceraceicola is distinguished from related New Zealand species by the combination of pruinose, central stipe and dark pileus.

Macromorphology

Pileus 5–20 mm, generally broadly convex to applanate, but sometimes campanulate when young, brick to purplish chestnut, minutely felty, radially furrowed and striate towards the margin, margin slightly fimbriate. Lamellae cream, creamy yellow to vinaceous buff, waxy, adnate. Lamellae present, in series of three: intercalated short/long/short. Stipe central, cartilaginous, 10–20 × 1–2 mm, equal, brown vinaceous, sometimes paler towards apex or base, always entirely finely pruinose. Stipe base insititious and always associated with a thin waxy to chalky cream layer of partially gelatinised hyphae covering the substrate. This layer is often extensive, with a distinct margin, and often green with algal cells. Fruitbodies with garlic/rotten cabbage smell, especially when crushed.

Micromorphology

Pileipellis a partially gelatinised radially arranged clamped cutis of smooth hyphae to 5 µm diameter, with brown extra-cellular encrustation. Epidermal layer to 140 µm. Subepidermis of thick glassy–walled non-gelatinised smooth hyaline hyphae, weakly dextrinoid. Basidia clavate to 40 × 8 µm. Sterigmata to 7 µm, 4–spored. Basidioles cylindrical, tapering towards apex, 40 × 4 µm. Spores hyaline, lacrymoid, 7.9 ± 1 × 4.5 ± 0.6 µm, Q = 1.8 ± 0.1 including apiculus. Cheilocystidia and pleurocystidia not observed. Stipitipellis a cutis of brown parallel hyphae, to 5 µm wide. Caulocystidia smooth, hyaline, agglutinated into fascicles.

Habitat

Colonies of a few to hundreds of fruitbodies on bark of fallen, dead branches and twigs, especially Nothofagus.

Distribution

Broadly distributed and common in both North and South Islands of New Zealand.

Etymology

Ceraceicola, indicating association with a basal waxy layer, although this feature is common to the three species described here.

Notes

Sequence data indicate variability in the taxon but the morphological details are constant and we choose to recognise a single species. New Zealand records of Gymnopus (Micromphale) foetidum and Gymnopus (Micromphale) brassicolens are attributable to Gymnopus ceraceicola. Authentic New Zealand material of these two species has not been identified. Gymnopus brassicolens has paler pileus colours, non-gelatinized pileipellis, cheilocystidia and pileipellis elements with lateral projections, and larger basidiospores. Gymnopus foetidus is macroscopically similar but does not possess the agglutinate fascicles of caulocystidia of Gymnopus ceraceicola.
