Species Information
Summary: Syzygospora bachmannii forms minute fruiting bodies on Cladonia and Cladina lichens. The fruitbodies are elongate, roundish, or irregular, colored reddish brown to pale or dark brown, waxy gelatinous in consistency, and identified by microscopic characters. The description is derived from Diederich(1).
Collections were examined from BC, and it occurs in Europe, Madeira, and Papua New Guinea, (Diederich(1)), as well as Panama (Diederich(2)).
Fruiting body: up to 0.5cm long, roundish or more often elongate, often irregular, sometimes tuberculate; waxy to gelatinous; "reddish brown, sometimes pale or dark brown"
Microscopic: SPORES 7-9 x 4.5-6 microns, elliptic or oval to almost limoniform [lemon-shaped], "obliquely attached to sterigmata, refractive at the point of attachment"; BASIDIA, when mature, (2)4-spored, 50-90 x 4-6.5 microns, cylindric, aseptate, epibasidia 5-12 microns long, 1-2 microns wide, subulate [awl-shaped], sterigmata refractive; HYMENIUM colorless, containing numerous probasidia, probasidial initials ellipsoid, proliferations occurring through the basal clamp connection; HYPHIDIA and CYSTIDIA absent; HYPHAE of context, 2-3.5 microns wide, thin-walled, with clamp connections, "haustorial branches frequent, tremelloid, with clamp connections, mother cell subspherical to ellipsoid", 2.5-4 microns in diam, haustorial filament 1-7 microns long, 0.5 micron wide; anamorph of two kinds: 1) "lunate germination conidia are present in many specimens", 2) catenate conidia with individual conidia subspherical to elongate, 2.5-5 microns in diam
Habitat / Range
on Cladonia lichens, on the podetia, rarely on the primary thallus
Similar Species
Syzygospora physciacearum has basidia 24-55 microns (Diederich(1)) and grows on Heterodermia, Physcia, and Physconia lichens, (Diederich(2)). Tremella cladoniae is pinkish brown to reddish brown, is generally confined to the squamules of the primary thallus (but can occasionally also grow on higher parts of the podetia), and differs microscopically, (Diederich(1)).
