Jalapriya pulchra D’souza, Su, Luo & K.D. Hyde

 

Index Fungorum number: IF551584Facesoffungi number: FoF 01265

Etymology: ‘pulchra’ meaning beautiful in Latin.

Holotype: HKAS 83979

 

Saprobic on decaying wood submerged in stream. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Colonies effuse, scattered, dark brown or black. Conidiophores micronematous, hyaline to pale brown, unbranched, thin-walled, smooth. Conidiogenous cells holoblastic, integrated, terminal, pale brown, smooth, thin-walled, becoming broader towards the apex. Conidia acrogenous, holoblastic, solitary, uniformly pale to medium reddish brown, composed of 5–7 rows, each row of cells with an apical hyaline, inflated, gelatinous subglobose, cap-like appendage, 2 outer rows arising from a basal cell, rows not separating, each row consisting of (4–)5–10(–12) cells, outer rows 32–46 μm long (x̄ = 39.5 μm, n = 25), excluding apical hyaline gelatinous cap, 23.5–31.5 μm wide (x̄ = 27.5 μm, n = 25), inner rows 23.5–37.5 μm long (x̄ = 30.5 μm, n = 25), 4.5–6.5 μm wide (x̄ = 5.5 μm, n = 25).

 

Culture characteristics: Conidia germinating on PDA within 24 h, germ tubes arising from the outermost cells of the conidium. Colonies on MEA covering 9 cm diam., in 4 weeks, at 28 °C, white to cream. Sporulation not observed in culture.

 

Material examined: CHINA, Yunnan Province, Dali, Cangshan Mountain, Lingquan stream, on decaying wood submerged in stream, March 2014, Zhuo Li, LQXM 47–1(S-013) (HKAS 83979, holotype), ex-type living culture, MFLUCC 15–0348.

 

NotesJalapriya puchra is similar to J. toruloides in the size of the conidia but differs in having hyaline appendages on the apical cells of the conidia. Jalapriya pulchra is also similar to J. inflata in conidial length but differs in having only complanate conidia and the conidia are wider in J. pulchra (23.5–31.5 μm) as compared to J. inflata (14.5–21.5 μm) (Matsushima 1983; Kirschner et al. 2013).
