Flammulina glutinosa G. Stev. 1964

Notes

Flammulina glutinosa Stevenson (29 D) Fig. 11 = Mycena leiana (Berkeley) Saccardo.

This is a unique, glutinous, deep orange coloured Mycena known only from North America. We compared the New Zealand specimen with material collected in the U.S. and did not find a single character separating the two. It may well be that M. leiana was accidentally introduced into New Zealand and should therefore be tentatively included in the list of the adventitious fungi.

Flammulina glutinosa G. Stev. 1964

Description

Pileus 1.5-2.5 cm diam., hygrophanous, fuscous, striate at margin, drying to olive buff, convex with or without a central dimple, exceedingly glutinous; flesh thin, fuscous to buff. Gills sinuately adnexed to adnate, orange to deep chrome yellow, thin, moderately crowded. Stipe 2-3 cm x 2-3 mm, fuscous to olive buff or orange towards the top, exceedingly glutinous, hollow. Spores 8-9 x 5 µm, non-amyloid, hyaline, thin-walled (Fig. 12); print white; sterile gill edge of loosely woven hyphae and sonic balloon cystidia with clear yellow contents. Cystidia not seen on gill faces. Basidia normal, 6 x 20 µm.

Habitat

Latin

Pileus 1.5-2.5 cm diam., hygrophanus, fuscus, margine striatus, exsiccando olivaceo-bubalinus, convexus, gelasino centrali interdum praeditus, quam maxime glutinosus; came tenui, fusca usque bubalina. Lamellae sinuato-adnexae usque adnatae, aurantiacae usque intense chromo-luteae, tenues, modice confertae. Stipes 2-3 cm x 2-3 mm, fuscus usque olivaceo-bubalinus vel apicem versus aurantiacus, quam maxime glutinosus, cavus. Sporae 8-9 x 5 µm, haud amyloideae, hyalinae, parietibus tenuibus; in cumulo albae; lamellae acies sterilis ex hyphis laxe intertextis et cystidiis nonnullis vesicularibus cytoplasmate claro luteo incluso sistens. Cystidia in lamellarum superficie haud visa. Basidia normalia, 6 x 20 µm.

Notes

Although this fungus has no cystidia on the gill faces or surface of the cap its affinities appear to the writer sufficient to place it in Flammulina. It also appears to have affinities with Tricholomopsis in the yellow gills with sterile margins.
