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 3–5 layers of brown textura angularis. On MEA forming sporodochia with mucoid conidial mass. Conidiophores cylindrical, hyaline, smooth, flexuous,1–3-septate, 50–100 × 3–4 µm. Conidiogenous cells terminal, cylindrical, hyaline, smooth, 20–50 × 2–3 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–)20–26(–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.
Figure 1. Consensus phylogram (50 % majority rule) of 18 452 trees resulting from a Bayesian analysis of the LSU sequence alignment (92 taxa including outgroup; 616 aligned positions; 426 unique site patterns) using MrBayes v. 3.2.6 (Ronquist et al. 2012). Bayesian posterior probabilities (PP) >0.74 are shown at the nodes and thickened lines represent nodes with PP = 1.00. The scale bar represents the expected changes per site. Families, orders, classes and subdivisions are indicated with coloured blocks to the right of the tree. GenBank accession or Fungal Planet numbers are indicated behind the species names. The tree was rooted to Phytophthora moyootj (GenBank KP004499.1) and the taxonomic novelties described in this study for which LSU sequence data were available are indicated in bold face.
