Tygervalleyomyces podocarpi

Tygervalleyomyces podocarpi Crous, in Crous et al., Persoonia 39: 387 (2017)

Etymology: Name refers to Podocarpus, the host genus from which this fungus was collected.

Diagnosis: Conidiomata cupulate, brown, up to 200 µm diam, forming on Podocarpus leaf litter; walls of 35 layers of brown textura angularis. On MEA forming sporodochia with mucoid conidial mass. Conidiophores cylindrical, hyaline, smooth, flexuous,13-septate, 50100 × 34 µm. Conidiogenous cells terminal, cylindrical, hyaline, smooth, 2050 × 23 µm, proliferating percurrently with proliferations widely dispersed over the length of the conidiogenous cell. Paraphyses similar to conidiophores but sterile, dispersed among conidiophores, frequently extending above them in length. Conidia solitary, cylindrical, with apex obtuse, base truncate with minute marginal frill, straight, aseptate, granular to guttulate, (18–)2026(–35) × 3(–4) µm.

Culture characteristics Colonies flat, spreading,with sparse aerial mycelium and smooth, lobate margins, covering the dish after 1 mo at 25 °C. On MEA, PDA and OA surface and reverse pale luteous

Index Fungorum number: IF823394

Notes: Tygervalleyomyces is a genus of coelomycetes with cupulate conidiomata with affinities to Typhulaceae. Based on a megablast search using the ITS sequence, the closest matches in NCBIs GenBank nucleotide database were only distant hits with members of Agaricales.
