Favolaschia manipularis (Berk.) Teng, Zhong Guo De Zhen Jun [Fungi of China]: 760 (1963)

Facesoffungi number: FoF 3139

Pileus 0.3–2.5 cm in diam., conico-campanulate to convex with conical umbo, translucently reticulate, hygrophanous, white pruinose, whitish, when moist greyish to hyaline, when dried up purely white to yellowish. Hymenophore tubular, adnate or adnate-emarginate with a slightly decurrent tooth. 1–5 mm long, white, arranged as radial rows, 5–7 in a row, with angular-round pores of 0.5–1.5 mm wide. Stipe 20–65 × 0.5–3 mm, hollow, hyaline to white, completely white, pruinose cylindrical, thickened in the base. Odour not distinct. Basidiospores 6–8 × 4–5 μm, Q = 1.2–1.6, smooth, white, ellipsoid to broadly ellipsoid and amyloid. Basidia 16–18 × 6–8 μm, narrowly clavate, clamped, with up to 6 μm long sterigmata. Cheilocystidia 51–75 × 7–13 μm, sterile lamellae edge, lageniform, subcylindrical or subclavate, mostly diverticulate or irregularly branched in the apex, simple lageniform with more or less developed neck. Pleurocystidia not visible. Hyphae of the pileipellis 5–16 μm wide, clamped, with diverticulate terminal cells. Pileocystidia 25–34 × 8–11 μm, abundant, irregularly shaped, lageniform to subclavate, with excrescences. Hyphae of the cortical layer of the stipe 3–8 μm wide, clamped, with diverticulate terminal cells. Caulocystidia 24–39 × 6–8 μm, abundant, irregularly shaped.

Habit, habitat and distribution: as a group, usually on dead or decaying wood, May to August. Our collection was collected on a decaying wood at Hanthana Mountains Range, Peradeniya.

Specimens examined: SRI LANKA, Kandy District, Hanthana Mountains Range, 3 June 2012, Samantha C. Karunarathna (MFLU 12-1172, new record) GenBank number ITS:KY649462.

Notes: The mycelium and fruiting bodies of the mushroom are bioluminescent. This is found in Australasia, Malaysia, and the Pacific islands and this is the first report of F. manipularis with the molecular phylogenetic confirmation from Sri Lanka.

Phylogenetic relationships inferred from maximum parsimony analysis of ITS-rDNA sequences of 31 taxa. The percentages of replicate trees in which the associated taxa clustered together in the bootstrap test (1,000 replicates) are shown next to the branches. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The new Sri Lankan records: Favolaschia auriscalpium having GenBank accession number KY649461 and herbarium number MFLU 12-1891; Favolaschia manipularis having GenBank accession number KY649462 and herbarium number MFLU 12-1172 (ITS-rDNA) are shown in bold and blue. The topology is rooted with Mycena crocata. Evolutionary analysis was conducted in PAUP 4.0b 10.
