Sowerbyella rhenana

https://www.mushroomexpert.com/Sowerbyella_rhenana.html

Ecology: Probably mycorrhizal (Tedersoo et al. 2010), growing gregariously or in loose clusters on the ground, usually in conifer woods; summer and fall, or over winter on the West Coast; apparently widely distributed in North America but more common in the west. The illustrated and described collections are from California and Michigan.

Fruiting Body: Cup-shaped, with a stem. Cups 18-25 mm across; upper surface bald, bright orange; under surface bald, pale orange; stem 10-25 x 3-5 mm, whitish to pale orange and downy when young, becoming orange and more or less bald; flesh orangish, not changing when sliced, brittle.

Odor: Not distinctive.

Microscopic Features: Spores 18-22 x 10-12 m; ellipsoid; smooth when immature, becoming ornamented with a thick, coarse reticulation; hyaline and uniguttulate in KOH; orangish golden in Melzer's. Asci 275-300 x 15-20 m; 8-spored; hyaline in KOH; tips inamyloid. Paraphyses exceeding the asci by 5-10 m; 3-6 m wide; cylindric with apices subclavate to clavate (occasionally with slightly irregular swellings), straight or hooked 45-90 degrees; septate; smooth; hyaline in KOH.

Rhubarb Bolete Boletellus obscurecoccineus is a species of fungus in the family Boletaceae, found in Australia, New Guinea, Java, Borneo etc. It has a rose-red or rhubarb-coloured, hemispherical to convex cap to a diameter of 7 cm (3 in), with an overhanging margin when young. The cap may crack in older specimen, found in leaf litter of eucalyptus forests. It has no distinctive odor. is an ectomycorrhizal species, meaning it has a symbiotic relationship with certain trees, forming a mutually beneficial relationship by sharing nutrients with the tree roots.

Stem: 4-8 cm long; 1-2 cm thick; fairly equal; with tiny scabers that are initially yellow but mature to reddish; overall appearing yellow at first, then slowly developing red colors from the base upwards; basal mycelium white.

Flesh: Pale yellow or whitish; not staining on exposure—or sometimes bluing slightly.

Odor and Taste: Not distinctive.

Chemical Reactions: Ammonia flashing green on cap surface, then resolving to gray; negative on flesh. KOH blackish on cap surface; orangish on flesh. Iron salts negative on cap; negative on flesh.

Spore Print: Olive brown.

Microscopic Features: Spores 10-12.5 x 3-4 m; fusiform; smooth; yellowish in KOH. Basidia clavate; 4-sterigmate. Hymenial cystidia not found. Pileipellis a trichoderm of inflated, chained elements (an epithelium); terminal elements either clavate to subglobose, 5-15 m across—or cylindric-cystidioid, 25-40 x 2.5-5 m, with rounded apices; both types smooth, hyaline in KOH, thin-walled. In cystidioid elements, subterminal cells sometimes swollen to various degrees.

#Fabricademy bootcamp 2025
May 19→25

Don't miss this year's bootcamp in Brussels to encounter international fellows in the field of #textile, #engineering and #biology.

I am co-organizing it through the #fablab @GreenFabric and the #fabricademy team (@fabtextiles ).

A great opportunity to test Fabricademy themes and way of working through intense hands-on workshops. It will cover #biomaterials with #mycelium #fungi, #modulardesign, #machineknitting with the #kniterate machine, using the #opensourcehardware machines that we built, #etextile with thermochromic inks.

Don't miss also the #MakerFaire on the following week-end (May 26-27) with the Fabricademy exhibition of final projects and a workshop on #softrobotics.

Boosts are more than welcome!

Not much in the way of spring mushrooms in my area but I did spot a couple showy Lichenomphalia and a shy pixie cup in the background. #fungi #mushtodon #yyj #victoriabc
