Clonóstachys rósea(lat.) Is a species ofascomycete fungi belonging to the genus Clonostachys of the Bionectriaceae family. Previously, this name refers only to the anamorphic stage of the fungus, and the teleomorph was called Bionéctria ochroléuca . Often included in the genus Gliocladium ( Gliocladium ) as Gliocládium róseum (Glyocladium rosy).

Description
Colonies on the 7th day up to 3.5-4.5 cm in diameter. Reverse on oatmeal (OA) is yellowish white, light yellow, then orangish or brownish, when cultivated in the light of light orange to orange-red, with a yellow soluble pigment released into the medium. Aerial mycelium abundant, felt or fluffy, forming cinnamon, most pronounced in the central part of the colonies. On the potato dextrose agar (PDA), the synems are well-orylated, erect, sporulation less abundant.
Conidiophores of two types. Primary conidiophores of Verticillium -type - with whitishly located fialida, bearing the mucous heads of conidia at the ends. Formed on hyphal substrate mycelium, throughout the entire colony, most abundant in its marginal zone. The legs are 70–200 µm long and 3.5–5.5 µm thick at the base, the branched part 30–120 µm long. Phialides 2-5 in a whorl (lower - sometimes single), spreading out, straight, somewhat thinning to the top, 23-31 microns long. Secondary conidiophores - two- - four-tiered brushes with adhered twigs and phialida (sometimes the first order branches diverging). The stem is 60–110 microns long, the tassel is 30–60 microns long. Phialides are sometimes somewhat curved, slightly flaky, 10.5–14.5 × 2.5–2.3 microns. Intercalary fialida rare. Conidia on primary conidiophores are almost straight, 7.5–9 × 2.5–4 μm. Conidia on secondary conidiophores are somewhat curved, flat on one side, 4.5–6 × 2.5–3 µm, in long mucous columns, sometimes coalescing into a single mucous mass.
Periterations are formed on the developed stroma , rarely directly on the mycelium, as a rule, from ascospore (very rarely from conidial) cultures. Aski narrow-bumped, 49-57 × 6.5-7.5 microns, eight-spore. Two -cell ascospores , usually prickly, 9.4–10.8 × 3–3.6 microns.
Ecology and meaning
Teleomorph is widespread in tropical regions, anamorph is often found in tropical and temperate regions.
It is found in the soil, on decaying wood, on the fruit bodies of fungi, as a parasite of nematodes, ticks, myxomycetes.
Used as a biological control agent for phytopathogenic fungi.
