A few alternative mushroom pics from the last month.

* Three Barometer Earthstars [Astraeus hygrometricus] forming a ladder up a mossy embankment.

* A small clump of bright orange Cinnabar Polypores [Pycnoporus cinnabarinus] that were either chomped or grew in with an odd shape.

* A moss covered branch with several glossy yellow Witches Butter [Tremella mesenterica] jelly mushrooms.

Three mushrooms are growing on a steep embankment, almost in a straight line. The top one is tucked into a little crevice between a flat rock and the base of the trunk. The bottom two are growing out of the side of the embankment at nearly a 90° angles, so that the tops are pointed directly at the camera. All 3 mushrooms look like creamy sacs atop dark grey and white star shaped starlike petals. The patterns are cracked looking.
Closeup of a bright cinnamon orange mushroom that spears to have been stunted somehow. There are three growths pointed north, east, and west with their inner parts joined. Each growth resembles a blob rather than any usual mushroom shape. They are growing on a damp birch branch that has fallen and also has green moss on it.
Looking straight down at a damp branch that is nearly entirely covered with green moss. Jutting out of the branch are 10 bright yellow fan shaped portions that look more like jelly candies than mushrooms.

Suillus pseudobrevipes

mushroomexpert.com/Suillus_pse

Ecology: Mycorrhizal with hard pines (those with needles in bundles of 2 or 3), especially lodgepole pine; growing alone, scattered, or gregariously; summer and fall; originally described from Idaho (Thiers & Smith 1964); distributed throughout western North America, in the natural range of lodgepole pine. The illustrated and described collections are from Colorado.

Cap: 5-12 cm; convex becoming broadly convex; slimy when fresh; bald; brownish yellow to yellow-brown, fading to tan; the margin with white veil remnants.

Pore Surface: Pale yellow, becoming darker yellow; not bruising; with 2-3 circular to angular pores per mm; tubes to about 1 cm deep; surface not boletinoid.

Stem: 2.5-6 cm long; 1.5-2.5 cm thick; tapering slightly to apex; whitish to pale yellowish above; whitish to brownish yellow below; sometimes bruising brownish; glandular dots usually tiny and concolorous with stem surface (nearly invisible without a hand lens) when young, sometimes becoming brownish to brown as the mushroom matures; often with a fibrillose, whitish ring, but sometimes with merely a whitish sheathing over the base, or without any visible veil remnants; basal mycelium white.

Flesh: White, or yellow above the tubes and in the stem; not staining when sliced.

Odor and Taste: Odor slightly fragrant; taste not distinctive.

Spore Print: Cinnamon brown.

Microscopic Features: Spores 6-9 x 2-2.5 m; boletoid-fusiform; smooth;hyaline to yellowish in KOH. Basidia 17-23 x 3-5 m; clavate; 4-sterigmate. Cystidia in bundles; 28-45 x 4-8 m; cylindric to clavate or subfusiform; smooth; thin-walled; hyaline to brown in KOH; often obscured by brown pigment globules. Pileipellis an ixocutis; elements 2-5 m wide, smooth, hyaline to brownish in KOH.

Introducing the New Zealand Bush Boba!

We found this pretty orange fungus last week during our survey of Mount Grand Station near Lake Hāwea, as part of the #LincolnUniversityNZ Masters-level Conservation Biology course.

The fungus is in the genus Heterotextus (thanks to Jerry Cooper on #iNaturalist for the ID). It doesn't seem to have had a common name, at least not until now. The students have declared it NZ Bush Boba, and I reckon that's good.

Four students gather around a stick with pretty orange fungi growing on it. Everyone is having a good time photographing it and thinking up a common name for it. https://inaturalist.nz/observations/270592844

Leucocoprinus cretaceus

mushroomexpert.com/Leucocoprin

Ecology: Saprobic; growing alone, in groups, or in loose clusters in potted plants, greenhouses, planters, and so on; appearing year-round; North American distribution uncertain, but apparently uncommon, and more likely to appear in tropical and subtropical areas. The illustrated and described collections are from California and Florida.

Cap: 2-8 cm; roundish or blocky and subcylindric when young, expanding to convex or nearly flat; dry; white; covered with small, wart-like scales.

Gills: Free from the stem; close or crowded; short-gills frequent; white.

Stem: 3-8 cm long; 5-10 mm thick; with a moderately swollen base; covered with soft scales like those on the cap; white; with a fragile, white ring; basal mycelium white; attached to white rhizomorphs.

Flesh: White; unchanging when sliced.

Odor: Not distinctive.

Spore Print: Reported as white to creamy.

Microscopic Features: Spores 6-12 x 4-7 m; subamygdaliform to ellipsoid; smooth; with a small pore; thick-walled; hyaline to slightly yellowish in KOH; dextrinoid. Basidia 4-sterigmate. Pavement cells present. Cheilocystidia 35-75 x 7.5-15 m; widely cylindric to widely fusiform or subcapitate; smooth; occasionally with refractive apical encrustations; thin-walled; hyaline in KOH. Pleurocystidia not found. Pileipellis a densely interwoven cutis of hyaline to yellowish, smooth elements 5-7.5 m wide; terminal cells occasionally cylindric but more often with branches and outgrowths, often forming shapes suggestive of letters or letter pieces, these elements 4-10+ m wide, smooth, occasionally with walls up to 1 m thick, hyaline in KOH, fragmenting.

Gyromitra esculenta.
A common fungus on southern Vancouver Island in early spring. Guidebooks list it as "toxic" and there have been fatalities recorded from consumption. The primary toxin, gyromitrin, is water soluble so boiling the mushrooms and discarding the water removes most of the toxin. But, gyromtrin hydrolyzes to monomethylhydrazine (aka rocket fuel) that is toxic when inhaled. So prepare them outside or in a room with good ventilation.
