Description

Substrate: Abies balsamea. On large masses of male cone bases from 2 years ago.

Habitat: High tide line along sandy beach, at the edge of a mature Picea rubens, Abies balsamea, Betula papyrifera, B. cordifolia forest. Alnus alnobetula abundant along high tide line.

Description: Discomycete. Stromata arising from the old points of attachment of male cones, black, globose with a central depression. Apothecia erumpent through the rind of the sclerotia, pale brown, furfuraceous, substipitate, with incurved margins, hymenium dark brown. Ectal excipulum of swollen, thin-walled, brown textura prismatica, medullary excipulum of loose, hyaline textura intricata. Subhymenium indistinct. Margin composed of thin-walled, brown, parallel hyphae. Paraphyses sparsely septate, sparsely branched, brown, giving the hymenium a distinct yellow-brown colour in cross section, thin-walled, 2.2-3.8mu wide, with swollen apices becoming 6.9-7.7mu wide, apical encrustations not observed. Asci unitunicate, 8-spored, uniseriate, 208-250x19-20mu, with an apical channel readily staining orange-brown in J, 3.1-4.0x6.0-9.2mu. Ascospores hyaline, ellipsoid-fusiform, often with one or both ends tapered to a point, 32-36x16-17mu, thin-walled and smooth-walled, lacking a gelatinous sheath.

Notes: Causes irregular density of male cones on branch tips, but this usually does not kill the branch.

Identification Reference: Sutherland et al. (1987) Cone and seed diseases of North American conifers

Found by @ikhom

fruitbodies on rotten wood, superficially similar to small slime molds, but were found to be Ascomycetes under the microscope

Ascoma are gymnothecial (loose tangle of rather undifferentiated hyphae with asci) vivid neon yellow, about 0.5mm in diameter, but quite conspicuous because of their colors

Asci are highly reduced, saccate, probably evanescent, the only evidence to their presence was the clumps of around 8 spores that were tightly clumped together that could occasionally be seen on the slide (picture 2 and 3). Ascospores are hyaline (orange? in mass) conspicuously ornamented under immersion oil and measure 3.3 - 3.8 x 2 - 2.7µm.

I seem to recall @Keith_seifert showing me this fungi many years ago, but I unfortunately do not remember what species this is.

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

little sporodochial anamorph on a twich of Populus sp. (probably).

Sporodochia up to 0.5 mm wide, effuse or even cupulate, vivid yellow, gelatinous when hydrated.

Conidiophore arise from a darkly pigmented basal stroma, conidiophore branched, somewhat phiallidic. Conidiogenesis unclear, conidia produced apicaly from elongated +- phialide like conidiogenous cells, might also produce a short bowl shaped collarette, but this is somewhat unclear.

Conidia smooth, globose 1.7-2.2

This organism seem to be quite similar to other collection using this name on the web. as I understand, the genus Dendrodochium is considered synonymous with Clonostachys. However, I do not believe this specific species is congeneric with Clonostachys, but as far as I know, it have not been studied recently, and its relationship with other species is unknown

A spore drop produced mostly aseptate, light brown, guttulate spores. Spores in ascus were darker brown and usually 3-5 septate, 57-72 x 4.8-6µm, Q=11.8.

Asci around 170-180 x 14-16µm.

Under mixed hardwood forests, mostly oak and beech.

On some sort of acorn, not sure which. I looked in the Champions du Suisse Tome 1 for these, and nothing really jumped out at me. I’ll take a look at spores and ascis later, and try and find better Asco sources for central Europe.

Adding some micro-details:

The micro-shot is of asci at 400x in Meltzer’s. The asci are 8-spored, and have slight blue reaction in the tip. The spores are curved, smooth, about 15 × 4 um in size. The paraphases are thin, with blunt ends.

The microscopic details match well with the descriptions of Rutstroemia echinophila from Champions du Suisse Tome 1. Except that species is supposed to be on chestnut husks. But since nothing else matched well, I go with the fact that also goes for acorns at times.
