Figs S1-S4 & Table S1

Figure S1. Mean conidial dimensions (with error bars representing standard error) for all herbarium specimens and cultures examined, with the holotype of H. fragiforme represented by orange bars and the holotype of H. callorioides represented by green bars.Figure S2. Lectotype of H. fragiformis (A, C, E) and holotype of H. callorioides (B, D, F). A, B. Rehydrated sporodochia. C−F. Conidial chains. Scale bars: A, B = 500 μm. C−F = 10 μm.Figure S3. Conidia and conidial chains. A. Oosporidium sp. (DAOM 970823) identified using DNA sequencing. B. Holotype of Sphaerocolla aurantiaca (H). Both have similar conidial morphology and dimensions, suggesting that S. aurantiaca may be conspecific with Oosporidium margaritiferum. Scale bar = 10 μm. Figure S4. Nuclear staining of hyphae of DAOMC 251988, showing dikaryotic, binucleate hyphae, A, using near-UV light showing the stained nuclei and B with regular light. Scale bar = 20 μm. Table S1. Species, geographical location, host and herbaria for known type specimens of Hormomyces species.
