Conidial stromata are shown. The 5 that are dark to the right were stained with diaminobenzidine hydrotetrachloride to visualize hydrogen peroxide in tissues.
This is another of the scale insect infecting fungi that infect the scale insect, consume it, then live on the sugars that leak to the surface through the insect's stylet wound. This is a member of the ascomycete family Clavicipitaceae. An article about this fungus is at link: https://www.sciencedirect.com/science/article/pii/S0953756207000159?via%3Dihub
This is Hyperdermium bertonii (or H. caulium). We established this genus to contain some species of ascomycetes that are scale insect infectors. These fungi infect the scale insect and consume it completely, then continue to grow on sugars that leak out of the stylet wound from the phloem of the plant. This fungus is a neurotrophic of the scale insect, and a biotroph to the plant. If the plant dies, the fungus dies. This fungus is common in tropical areas.
This is an ascomycete (family Clavicipitaceae with ergot) that is endophytic in warm-season grasses. These are the kind of fungi that iNaturalist cannot identify due to absence in the dataset.
Host is grass Dactylis glomerata. This fungus is endophytic in grasses.
This was on oak. You can see the bark on the tree behind the fungus.
