Colonies on corn-meal agar light yellow, growing sparsely; vegetative hyphae colorless, sep- tate, thin walled; rhizoids present; sporangiophores scattred, yellowish, erect, irregularly branched, mostly 10-17.5 μm in diam, up to 1 cm or more high, smooth, thick-walled, with conspicuous septa, branching several times, tapering above and terminating in a single sporo- cladium, usually over severn sporocladia present on one sporophore; sporocladia usually arranged in a zigzag pattern on the sporangiophore axes, 13-39 × 18-47 μm, sessile, non-septate, dome-shaped, bearing numerous pseudophialides crowded over the upper surfaces; pseudophialides ellipsoidal, 6-8× 2-3 μm, with small apical projections bearing the sporangiola; sporangiola nearly hyaline, elongate-clavate, 19-25 (aver. 22) × 3.8-4.2 μm, enveloped in liquid at maturity ; sporangial wall projecting about 2-3 μm beyond the apex of the spore as a hyaline enlargement of the tip; sporangiospores lanceolate, 16-22 (aver. 19) × 3.8-4.2 μm near the base, uniformly tapered to the acute apices, round below. Zygospores not observed.
Colonies on potato-dextrose agar maize yellow, vegatative hyphae branching irregularly, growing luxiously, sporangiophores rare, bearing relatively less sporocladia than on CMA, usually less than three sporocladia forming on one sporangiophore.
Notes This species is distinguished from the relative species L. .macrospora by it’s smaller (16-22 × 3.8-4.2 μm) sporangiospores, which is larger (26-36 x 3-5 μm) in the later one (Chang, 1967).

Both species ofLinderinahave been isolated from soil. The colonies of both species are yellow and they grow well on relatively nutrient-rich culture media.Linderina pennisporafills the Petri dish with aerial hyphae and sporocladia are produced from the upper portion of the sporangiophore.Linderina macrosporaproduces fewer sporocladia. Both species have been isolated at least one other time from soil in addition to the original isolation. Cole and Samson (1979) and O’Donnel (1979) both have publishedSEMphotographs ofLinderinaspp. (Zygomycetes 2015)
