Hobsonia is a genus of fungi in the family Phleogenaceae. [1] The genus is currently monotypic, with a single recognized species, Hobsonia mirabilis. The type species, H. gigaspora, and H. ackermannii are considered to be synonyms [2] and additional lichenicolous species have now been transferred to the ascomycete genera Hobsoniopsis and Illosporiopsis . [3] Hobsonia mirabilis is only known in its anamorph form, which is whitish, gelatinous, pustular, and occurs on dead woody plant remains. Microscopically, it produces coiled or spiralled conidia. [2] The species was formerly of uncertain disposition, but molecular research, based on cladistic analysis of DNA sequences, has shown that it belongs within the Atractiellales. [1] [4] Though originally described from New York, the species is more commonly found in the tropics and subtropics. [2]
