(RMBL-L-13) Genistelloides helicoides Williams & Lichtwardt (Harpellales,
Legeriomycetaceae) from the hindgut of a stonefly nymph (Zapada haysi)
from a Rocky Mountain stream. Developing trichospores. Note the coiled
appendages within the generative cells from which the trichospores grow.
In this genus the appendages become visible before the exogenous
trichospores begin to develop.
(RMBL-M-17) Genistelloides helicoides. Released trichospore with two
coiled appendages. Appendages may function to restrain spores from
drifting downstream, thus retaining them in the vicinity of the host
population and leading to possible ingestion and germination in the
(HAW-A-34) Smittium culisetae Lichtwardt (Harpellales, Legeriomycetaceae).
Sporulating thallus and released trichospores with a single appendages.
Axenic culture (JAP-77-8) made from the hindgut of a mosquito larva
collected in a stone trough at a Shinto shrine in Japan. This fungus is
worldwide and usually inhabits mosquito larvae, but is known to occur in
several other families of dipteran larvae.
(MBL-E-8) Smittium alpinum Lichtwardt Biconical zygospores and
oval trichospores. From the hindgut of an aquatic midge larva near
the continental Divide in Glacier National Park. The fungus is known
only from larvae of Diamesa sp. (Chironomidae) from the Rocky
Mountains, the Alps, northern Sweden.
(MBL-HH-29) Stachvlina pedifer (Williams & Lichtwardt Harpellales,
Harpellacae) in the peritrophic membrane (midgut) of a midge larva
(Boreoheptagyia lurida) from turbulent waters of a Rocky Mountain
stream. The simple, holocarpic thallus of this species, usually with 4
trichospores, penetrates through the peritrophic membrane as a means
of attachment, an unusual feature in the Harpellaceae.
(KU-32) Arundinula abyssicola Van Dover & Lichtwardt (Eccrinales,
Eccrinaceae). Unbranched thalli producing sporangiospores. From the
stomach (foregut) of a galatheid squat lobster (Munidopsis subsquamosa)
collected at 2600 m depth at the "Rose Garden." One of several
hydrothermal vent sites in the Galapago Rift where this eccrinid has been
found. The fungus has also been collected at a hydrothermal vent in the
East pacific Rise.
