Periconia submersa

Periconia submersa Z.L. Luo, Hong Y. Su & K.D. Hyde

Index Fungorum number: IF552829; Facesoffungi number: FoF 02942

Etymology: with reference to the submerged habitats of this fungus.

Holotype: HKAS 92738

 

Saprobic on submerged decaying wood. Sexual morph: Undetermined. Asexual morph: Colonies on the substratum superficial, numerous, effuse, dark brown to black, floccose. Mycelium partly superficial, composed of septate, hyaline hyphae. Conidiophores macronematous, mononematous, unbranched, erect, straight or slightly flexuous, single, septate, brown, 485.5–529.5 μm (x̅ = 507.5 μm, SD = 22 μm, n = 10) long, 11–12 μm (x̅ = 11.5 μm, SD = 0.5 μm, n = 10) wide, the apex forming sphaerical heads. Conidiogenous cells monoblastic, terminal, pale brown, discrete on stipe and branches. Conidia solitary, subglobose, globose, cuneiform, brown, verruculose, 6.5–9.5 lm (x̅ = 8 μm, SD = 1.5 μm, n = 30) long, 4.5–5.5 lm (x̅ = 5 μm, SD = 0.5 μm, n = 30) wide. (Descriptions from Hyde et al. 2017)

 

Material examined: CHINA, Yunnan Province, saprobic on submerged decaying wood in the Nujiang River, 3 May 2015, X.J. Su, N4–8–1 (HKAS 92738, holotype), ex-type living culture MFLUCC 16-1098.

 

Notes: Periconia submersa is phylogenetically close and morphologically similar to P. aquatica, however, P. submersa differs from P. aquatica in having smaller, cuneiform conidia. Sequence similarity between these two taxa in the ITS regions was 95.9% (490/511). (Notes from Hyde et al. 2017)
