Coniella eucalyptorum

Coniella eucalyptorum (Crous & M.J. Wingf.) L.V. Alvarez & Crous in Alvarez, Groenewald & Crous, Stud. Mycol. 85: 15 (2016)

Index Fungorum number: IF817817         Facesoffungi number: FoF07370


Sexual morph: Undetermined. Asexual morph: Conidiomata 90−130 μm high × 160−200 μm in diameter (n = 10) solitary, globose, brown and dark brown from the top. Conidioma wall consisting of 2–3 layers of hyaline textura prismatica and 4-5 layers of brown textura angularis cells. Conidiophores densely aggregated, branched. Conidiogenous cells 12–15 × 1–2 μm, annellidic, narrowing at the tip, smooth and hyaline. Conidia 10−12 × 3−6 μm (x̄ = 11 × 5 μm, n = 30), hyaline to pale brown, becoming dark brown at maturity, smooth, broadly ellipsoidal, both sides gradually tapering, smooth-walled, and multi-guttulate with one or two prominent guttules.


Culture characteristics: Colony on PDA reaching 30 mm diameter after 7 days at 25 °C, colony circular, margin wavy, flat, velvety appearance, colony from above: light brown; reverse: dark brown.


Habitat: Saprobic on dead leaves of undetermined host.


Known hosts: Eucalyptus sp., Corymbia nesophila, Corymbia torelliana (Alvarez et al. 2016), unidentified host (Hyde et al. 2020).


Known distribution: Australia, Brazil, Chile, China, Indonesia, Malaysia, Mexico, Venezuela, Vietnam (Alvarez et al. 2016), Thailand (Hyde et al. 2020).


Material examined: Thailand, Chiang Mai Province, Mae Taeng, Ban Pa Deng, Mushroom Research Centre, on twigs of unidentified host, 27 May 2016, N.I de Silva, NI106 (MFLU 17–0675), living culture, MFLUCC 17–0870.


GenBank Accession No: ITS: MN836684, LSU: MN836664


Notes: Phylogenetic analysis of combined ITS, LSU, histone and TEF1 sequence data confirmed that our collection is Coniella eucalyptorum with high support. Coniella eucalyptorum was previously recorded from Australia, Brazil, Chile, Indonesia, Malaysia, Mexico, Venezuela and Vietnam (Alvarez et al. 2016). Coniella eucalyptorum was commonly recorded from Eucalyptus sp. (Alvarez et al. 2016). This is the first record of C. eucalyptorum from twigs of unidentified host in Thailand.
