Lecanicillium uredinophilum

Lecanicillium uredinophilum M.J. Park, S.B. Hong & H.D. Shin, Mycotaxon 130(4): 1002 (2016) [2015]

Index Fungorum number: IF814832, Facesoffungi number: FoF 04115

Asexual morph: Conidiophores arising from prostrate hyphae and bearing up to 1–4 whorls of phialides. Phialides 15–35 × 0.5–2 (x̄ = 22 × 1.2, n = 30) μm, gradually tapering towards the apex, aseptate, phialidic, hyaline, occasionally producing secondary branch. Conidia 3–6 × 1.1–2.3 μm (x̄ = 4.5 × 1.6, n = 30), oval to cylindrical, aseptate, smooth-walled, hyaline, aggregating in slimy head on the tip of phialides. Sexual morph: Undetermined. (Wei et al. 2018)

Culture characters: Colonies growing on PDA reach 2 cm diameter after 12 days at room temperature (about 26°C), white, velvety-cottony, irregular, umbonate; pale yellow from below.

Known hosts and distribution: On uredinia of Pucciniastrum agrimoniae on Agrimonia pilosa (South Korea) (Mijeong et al. 2015) or on  decayed insect attached to lower surface of pear leaf (China: Yunnan) (Wei et al. 2018).

RAxML (ML) phylogenetic tree generated from analysis of a combined LSU, SSU, tef1-α, RPB2, RPB1 and ITS sequences dataset for 41 isolates of Lecanicillium and Simplicillium lanosoniveumas (outgroup). ML support values greater than 70% (left), MP bootstrap value higher than 70% (middle) and Bayesian posterior probabilities greater than 0.95 (right) are indicated near the nodes. Strains generated in this study are in blue bold. (Wei et al. 2018).
