Aplosporella prunicola

Aplosporella prunicola Damm & Crous, Fungal Diversity 27(1): 39 (2007).

Index Fungorum number: IF 504373; Facesoffungi number: FoF 04955;

 

Sexual morph: Undetermined. Asexual morph: Conidiomata 500–1000 × 200–375 μm (x̄= 625 × 265 μm, n = 5), pycnidial, solitary, scattered, gregarious, immersed to semiimmersed, erumpent, globose to subglobose, coriaceous, uni-loculate, dark brown to black, ostiolate. Peridium 30–40 μm wide, well developed, composed of several layers, inner two layers composed of thin-walled, hyaline, cells of textura angularis, outer three layers composed of dark brown, cells of textura angularis, becoming hyaline towards the inner region. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 5–6 × 1–2 μm (x̄ = 5.5 × 1.3 μm, n = 30), holoblastic, hyaline, cylindrical to doliiform, smooth-walled. Conidia 12–16 × 6–9 μm (x̄= 14.5 × 7.8 μm, n = 30), aseptate, broadly ellipsoid to subcylindrical, with rounded ends, initially hyaline, becoming brown to dark brown, smooth-walled.

 

Culture characteristics: Colonies on PDA reaching 25 mm diam after 2 weeks at 20–25 °C, colonies medium sparse, circular, flat, surface slightly rough with edge entire, margin well-defined, cottony to fairly fluffy with sparse aspects, colony from above: white to cream at the margin and the centre; reverse, white to grey margin and the centre; mycelium white to grey with tufting; not producing pigments in PDA.

 

Habitat: Ficus septica (Moraceae), Prunus persica and P. nucipersica (Rosaceae).

 

Known distribution: Thailand.

Notes: As phylogenetic analysis and morphological characters examined largely overlap with those of Aplosporella prunicola, we would like to report our collection as a new host record.
