Description

Finally! After all these years, I am able to see this peculiar species!

Found growing on wet, rotten, wood of Populus tremuloides

synnemata, isolate, +- indeterminate, white, with transluscent stipe. Clamp connection at some septa. Conidiogenesis not observed. Conidia, hyaline, flat, formed with four symmetrical lobes, giving it the appearance of a Four-leaf clover or a poppy flower. Conidia probably attached flat on the top of the conidiophore. Conidia measure 9 - 12µm in length. and about 4-6µm in height.

Conidia, rarely, with 5 lobes, perhaps finding one is a sign of good luck

The distinctive conidia, synnematous conidiomata and clamps connection make this species unique

Description

Common Coelomycetes on old fallen cones of Picea

exact host in this case a bit unclear, either Picea abies of Picea pungens, which are both commonly planted in the area

conidiomata, immersed or somewhat erumpant, opening from a large irregular slit, conspicuous on scales of the host.

Conidia produced in basipetal chains (in which the youngest conidia is at the base of the chain). Chains are fragile, and break readily and. Conidia birostrate (appendages at the top and bottom), and often with various protuberance on the sides. Conidia smooth, dictyoconidia, with several lateral and longitudinal septa, in the center. Conidia pigmented, but paler on the rostrums and protuberance.

Conidia measure 25 - 40(48)µm x 12 - 22 µm (avg = 31.7 x 16.8).

Common on this substrate

Description

found on a twig, probably Populus

conidiomata, sporodochial, erumpant, orange when dry (Picture 2), pale pinkish when fresh (Picture 4), with a darker short, stout stem. Conidiophore arising from somwhat stromatic cells of textura angularis. Conidiophore, long, often curved, hyaline, conidiogenous cells produced pleurogenously, as small strongly apically curved phialides, usually found below a conidiophore septum. Conidia, hyaline, aseptate, smooth, somewhat variable in shape and occasionally slightly sinuous, allantoid or constricted at the center. Conidia measure 5.5 - 7.5 µm x 1.8 - 2.3 µm (avg = 6.6 x 2.1).

This relatively common and distinct species here because of its coloration, large size and pleurogenous conidiogenous cells, it often grow on twigs and small branches. It also, often have a teleomorph associated with it, but it was not seen in this collection.

Nectria dematiosa is apparently similar but without a stout stem, while N. canadensis is decidedly synnematous and occur on elm.

synnema tapered upwards, apex sterile, with lateral loose hyphae, conidia dry, not catenate. The shear number of condia suggests this is phialidic or anellidic but it isn't easy to see. Conidia length=3.4–4.0µm (µ=3.7, σ=0.2), width=2.2–2.5µm (µ=2.4, σ=0.1), Q=1.5–1.7µm (µ=1.6, σ=0.1), n=7

Description

Grown in moist chamber from bark of Pinus strobus collected from this location on the 30 December 2021

Small hyphomycetes. Colonies isolated on the bark of the host, Conidiophore consisting of a venter topped by a collarette. Venter appear rough, is enlarged and easily differentiated, paler than the collarette, and measure 30 - 70 x 12 - 15 µm. collarette much darker and slimmer and generally longer than the venter, measuring (60-)75 - 100 x 8 - 10.µm Conidiophore aseptate and its total length is 100 - 175 µm. Conidia produced inside the collarette and protruding at the top (a bit like smoke from a smokestack), often in long fragile chain several time longer than the conidiophore. Conidia are hyaline and generally 7 septate (rarely 6 or 8 septate), oblong with somewhat truncate ends or somewhat rectangular. Conidia measure (30-)38 - 48 x (6-)6.5 - 7.5(-8.5) µm (avg = 41.2 - 7.1).

The genus Chalara is relatively distinctive by produce hyaline truncate conidia inside an highly elongated, often dark, collarette.

This species was identified using the Key by Nag Raj and Kendrick (1975) as it fit almost perfectly all descriptions in the key. Chalara bicolor is very similar but produce conidia generally longer than 50µ and with a width less than 6.5µ. C. pulchra is also similar but lack a differentiated venter and have wider conidia at least 8.5µm in width. (Nag Raj and Hughe, 1974)
