I went out trekking on a riverside today and they are the findings:

1. Wild cherry tree. 🌸🍂
2. Curly shoot of a giant fern. 🌀
3. Mysterious blobby mushroom. 🐙
4. An underwater egg, or eggshell, of a salamander. 🦎

Yes, it was a good day! 😆

Volvopluteus gloiocephalus

mushroomexpert.com/Volvopluteu

Ecology: Saprobic; growing terrestrially, alone or gregariously in urban settings and disturbed ground (landscaping, ditches, beaches, lawns, gardens, and so on)—and, east of the Rocky Mountains, sometimes in forests; found year-round, depending on the climate; widely distributed in North America, though some records of it from east of the Rocky Mountains may represent other similar species, including the smaller-spored Volvopluteus michiganensis. The illustrated and described collections are from California and Illinois.

Cap: 5-10 cm across; convex becoming broadly convex, broadly bell-shaped, or nearly flat; sticky when fresh and young but often soon dry; bald; color variable (see discussion above), white to grayish or gray, discoloring brownish to yellowish with age; when gray, with a radially streaked, appressed-fibrillose appearance; the margin sometimes finely lined.

Gills: Free from the stem; close or nearly crowded; short-gills frequent; white at first, becoming brownish pink with maturity.

Stem: 6-13 cm long; 1-2 cm thick; tapered to apex; base slightly swollen; dry; bald or finely silky; white, discoloring brownish; without a ring; the base encased in a white, cup-like volva; basal mycelium white.

Flesh: White; not changing when sliced.

Odor and Taste: Not distinctive, or a little foul.

Chemical Reactions: KOH negative on cap surface.

Spore Print: Brownish pink.

Microscopic Features: Spores 13-19 x 7-10 m; ellipsoid; thick-walled; smooth; hyaline to yellowish in KOH. Basidia 4-sterigmate. Cheilocystidia and pleurocystidia 50-80 x 20-40 m; widely lageniform, widely cylindric with a rounded apex, subsaccate, or sphaeropedunculate; sometimes mucronate or rostrate (see discussion above); smooth; hyaline in KOH. Pileipellis a cutis of elements 5-12.5 m wide, smooth, hyaline in KOH, under a very thin gelatinous matrix. Clamp connections not found.

Russula dissimulans

mushroomexpert.com/Russula_dis

Ecology: Mycorrhizal with hardwoods or conifers; growing alone, scattered, or gregariously; summer and fall (and over winter in warm climates); widely distributed in North America.

Cap: 5-20 cm; broadly convex when young, later flat with a central depression, or shallowly vase-shaped; dry; more or less smooth, but with a waxy feel; initially whitish but soon discoloring to brownish, ashy gray, or brown (eventually almost black); the margin not lined; the skin not peeling easily.

Gills: Attached or running very slightly down the stem; thick; distant or nearly so; white to cream; bruising and discoloring slowly reddish, then grayish to blackish.

Stem: 3-8 cm long; 1-4 cm thick; whitish at first, but soon darkening like the cap; bruising reddish, then blackish over the course of as much as half an hour; fairly smooth.

Flesh: White; hard; bruising promptly or slowly reddish on exposure, then blackish over the course of as much as half an hour or more.

Odor and Taste: Odor slightly fragrant, somewhat unpleasant, or not distinctive; taste mild, slightly acrid, or acrid.

Chemical Reactions: KOH on cap surface negative. Iron salts on stem surface negative to weakly grayish.

Spore Print: White.

Microscopic Features: Spores 6-11 x 6-9 ; widely elliptical to subglobose; with ornamentation under 1 high, connectors forming partially to completely reticulate areas. Pileipellis <NOBR>20-150 </NOBR> thick; cutis-like, with horizontal elements, tightly interwoven; in KOH "with globules of brown
pigment giving them the appearance of transparent intestines" (Roberts, 2008); not embedded in a gelatinous matrix; pileocystidia absent.

Cyathus olla

mushroomexpert.com/Cyathus_oll

Ecology: Saprobic; growing scattered, gregariously, or in dense clusters; sometimes growing terrestrially, but often found on woody debris; frequently encountered on dead plant stems, including corn husks in cornfields and debris in canola fields; summer and fall; widely distributed in North America.

Nest: 8-15 mm high; 6-10 mm wide; cup-shaped or goblet-shaped; outer surface brownish to grayish, bald or minutely hairy to velvety (but not conspicuously hairy); inner surface bald and shiny, silvery gray to blackish; "lid" typically whitish to pale grayish, soon disappearing; outer edge flared open widely by maturity, frequently broadly wavy.

Eggs: To 3 or 4 mm wide; round to somewhat irregular in outline; usually somewhat flattened; gray to gray-brown or nearly black; sheathed; attached to the nest by cords.

Microscopic Features: Spores 10-14 x 6-8 m; ovate to ellipsoid; smooth.

Calvatia cyathiformis

mushroomexpert.com/Calvatia_cy

Ecology: Saprobic; growing alone, scattered, gregariously, or in fairy rings in grass (lawns, golf courses, parks, pastures, etc.); summer and fall; widely distributed in North America, but possibly absent on the West Coast. The illustrated and described collections are from Illinois and Qu&#233;bec.

Fruiting Body: 8-17 cm high and 8-20 cm wide when mature; ball-shaped when young, but soon developing a thick basal portion that is slightly more narrow than the upper portion; at maturity usually shaped like an inverted pear or a loaf of bread.

Outer Surface: Tan to pale brown; the pigment breaking up into small, mosaic-like scales; eventually becoming very pale brown to grayish or nearly white, with a vague mosaic of sections punctuated by brownish dots; dry; the skin 1-2 mm thick.

Interior: White and firm when young; soon becoming two-chambered texturally, with the basal portion distinct from the upper portion; upper portion becoming yellowish and finally deep brownish purple as it matures and turns into spore dust; basal portion turning yellowish, then olive with age.

Over-Mature Specimens: After the top ruptures and the spore mass is dispersed, the sterile base can remain, cup-like, with a ragged upper edge, for weeks.

Odor and Taste: Not distinctive.

Chemical Reactions: KOH negative on outer surface.

Spore Dust: Purple.

Microscopic Features: Spores 3-6 m (including ornamentation); globose; covered with spines 0.5-1 m long; hyaline in KOH; brownish in Melzer's reagent. Capillitial threads 2-5 m wide; walls about 0.5 m thick; hyaline in KOH; smooth or very minutely pitted; a little narrowed at septa.

Conocybe apala

Cheilocystidia 20-28 x 7-14 m; lecythiform with a subglobose head 2-4 m wide, a narrow (2 m) neck, and an obclavate bottom portion; smooth; thin-walled; hyaline in KOH. Pileipellis cellular; terminal elements 5-30 m wide, subglobose, smooth, hyaline in KOH.
