Small clumps of white fungi growing on sods of wet forest soil in complete shade. I often see this type of fungi after heavy rainfall but I managed to get better images of this fungi in this record find.

Hi Ian

I agree with the suggestion of Chromelosporium. You have a conidial fungus in which the conidiophores are united to form what are called synnemata (the singular is synnema). You have what looks like a trunk made up of bundles of septate hyphae and there is a dichotomous branching of the apices of the individual conidiophores. So you get a spreading crown, to continue the tree analogy. The photo shows two branching points on one conidiophore, with a split into two at each point. You see masses of globose conidia on the blunt-ended branches. The photo has false colouring since I wanted to emphasize the branching against the background. The conidia are hyaline in KOH, about 5-6 mu in diameter and either smooth or with a very fine, verruculose ornamentation.
