We've had several days of unseasonably hot and humid weather for autumn. The dew point reached 26°C, making the climate as humid as in the Amazon. Yes, it's Buenos Aires and we're relatively close to the Atlantic coast, but for autumn this is not normal. My asthma has been bothering me quite a bit these days.
But what surprised me most is that one of the trees I have at home grew huge mushrooms, about 15 cm tall, in just 3 days. I think they're very beautiful and they're not toxic to animals. Anyway, my cats ignore them; it's lizard season.

Wolfina aurantiopsis

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

Ecology: Saprobic on decaying hardwood sticks (which are sometimes buried); growing scattered to gregariously; summer and fall; Connecticut to Florida, west to Ohio. The described and illustrated collections are from North Carolina and Ohio.

Fruiting Body: Cup shaped when young, becoming broadly cup shaped with age; 3-7 cm across; upper surface pale to bright yellow, bald; outer surface dark brown to nearly black, woolly to hairy, becoming more bald with age; flesh firm, yellowish to watery grayish, turning slowly purplish when sliced; odorless.

Chemical Reactions: KOH and iron salts both negative on upper surface and on flesh.

Microscopic Features: Spores 22-30 x 12-16 at maturity; very shallowly and subtly ridged lengthwise (best seen with cotton blue) but often appearing smooth or nearly so; ellipsoid; cyanophilic; hyaline, with granular contents, in KOH. Asci 8-spored; 200-300 x 10-15 ; thick-walled; hyaline in KOH; tips inamyloid. Paraphyses filiform; 250-300 x 2.5 ; septate several times; apices rounded or subacute. Excipular surface elements (hairs) 7-10 wide; often thick-walled; brownish to brown in KOH; finely warted or spiny ("prickled" in the words of Eckblad, 1968) walls near the basal portion, but smooth above.

Lycoperdon perlatum

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

Ecology: Saprobic; growing alone, scattered, gregariously, or in clusters; in woods under hardwoods or conifers, but also common along roadsides and in urban settings; late spring through fall in temperate regions, but also over winter in warm climates; widely distributed and common in North America. The illustrated and described collections are from Illinois, Colorado, and Italy.

Fruiting Body: Usually shaped like an inverted pear or a cushion, with a fairly prominent sterile base and a roundish or somewhat flattened top; 2-7 cm wide; 3-8 cm high; dry; whitish to very pale brownish when young, becoming brown with age; covered when fresh and young with cone-shaped, wide-based, firm spines about 1 mm high (often with well-spaced larger spines surrounded by smaller spines and/or granules); spine tips often becoming brownish to brown; surface, after spines have fallen off, pock-marked where the spines were attached, sometimes in a reticulate pattern; outer skin paper thin; developing a central perforation through which spore powder is liberated by rain drops and wind currents; interior flesh white and spongy at first, later olive to olive brown above and yellowish to brown in the sterile base; spore powder olive brown at maturity; base attached to thin white rhizomorphs.

Microscopic Features: Spores 4-5 m; globose; finely verrucose; greenish yellow in KOH. Basidia 5-6 c 5-6 m; subglobose; 4-sterigmate with long (about 3 m) sterigmata; smooth; hyaline to yellowish or brownish in KOH. Capillitial threads 2-5 m wide; hyaline to olive or brown in KOH; walls 0.5-1 m thick; with scattered tiny pores.

With two feet + of snow covering everything the last couple months, mushrooms have been hard to come by. But with the rapid melting over the past 10 days these Amber Jelly Rolls [Exidia recisa] have been uncovered and are ready for their flabby closeups.

Leucocoprinus fragilissimus

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

Ecology: Saprobic; growing alone or scattered, in humus; summer; distributed in the southeastern United States, from Texas to the southern Appalachians; also reported from Costa Rica. The illustrated and described collection is from Ohio.

Cap: 1.5-4.5 cm across; planoconvex, becoming nearly flat, with a small central bump; very fragile, and soon collapsing; deeply grooved from the margin to the center; dry or moist; pale greenish yellow, with a slightly darker center; fading to nearly white, with a yellowish center.

Gills: Free from the stem; distant; pale yellow; often dissolving in hot weather.

Stem: 4-9 cm long; 1-2 mm thick; equal above a small basal bulb; exceedingly fragile; bald; pale yellow, fading to nearly white; with a thin, fragile, yellow ring that sometimes disappears.

Flesh: Insubstantial; yellowish.

Odor: Not distinctive.

Chemical Reactions: KOH negative on cap surface.

Spore Print: White.

Microscopic Features: Spores 9-12 x 7-8 ; broadly ellipsoid; with a large (2 ) pore at one end, creating a sublimoniform impression; smooth; hyaline in KOH; dextrinoid. Brachybasidioles abundant in young caps. Pleurocystidia absent. Cheilocystidia clavate; soon collapsing. Pileipellis cellular/hymeniform; terminal elements subglobose, 15-25 wide, hyaline in KOH.
