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.

PSA: Missouri Dept of Conservarion is holding a virtual mushroom hunting webinar this Saturday. I believe this is just for residents of Missouri. Looks pretty darn cool. LOVE the MDC learning stuff. Missourians are so lucky to have a great conservation department.

Warty Cavalier (Melanoleuca verrucipes): Usually found in the late summer and autumn, this mushroom was first recorded in the UK only in 2000*, and is mostly found in the south of England. Well, this one appeared in my garden in the Central Belt of Scotland last Friday (11 April)! It popped out in an old abandoned flower pot. ... #Mushrooms, #Fungi, #Nature, #Microscopy: aye.tf/2025/04/14/melanoleuca-

Yesterday, I helped co-lead my first mushroom walk hosted by the Discovery Center in Philadelphia. It was cold and rainy, but we still had a decent turn out of 20-ish people? I haven't worked much with my co- before, but I'm thankful that it went well, and the host organizer was very easy to work with too. We walked along a path that I had had a chance to scope out a month earlier, which was really helpful as someone not as confident about leading trails. The practice run with her made me realize I might know more than I expected- at least enough for the purposes of the event. It was hard to find specimens in the cold, but not impossible, including wood ears and oysters. I think people who attended had a good time and got to come away with some good fungi fun facts like how it's safe to touch mushrooms or how to use iNaturalist. I'm really thankful for this opportunity.

Rickenella fibula

Ecology: Probably saprobic but apparently involved in some sort of mutualism with moss; growing alone, scattered, or gregariously in moss beds; spring through fall, or over winter in warm climates; widely distributed in North America. The illustrated and described collections are from Illinois.

Cap: 2-10 mm across; blocky or squarish at first, becoming convex, then broadly convex, with or without a shallow central depression; tacky when fresh but soon dry; bald or, with a hand lens, very finely hairy; the margin translucent-lined by maturity; orange with a whitish margin when fresh and young; soon fading to yellowish orange overall, with a darker orange center.

Gills: Running deeply down the stem; distant or nearly so; short-gills in several tiers; creamy or very pale orange.

Stem: 5-45 mm long; 0.5-1.5 mm thick; equal; dry; bald; colored like the cap; basal mycelium white.

Flesh: Insubstantial; pale.

Odor and Taste: Not distinctive

Chemical Reactions: KOH negative on cap surface.

Spore Print: White.

Microscopic Features: Spores 3-4 x 1.5-2.5 m; ellipsoid; smooth; hyaline and 1- to 3-guttulate in KOH; inamyloid. Cheilocystidia and pleurocystidia 25-40 x 5-7.5 m; fusiform with tapered or subcapitate apices; thin-walled; hyaline in KOH; smooth. Pileipellis a tightly packed cutis with numerous pileocystidia 50-100 x 7.5-12.5 m, fusiform with wide bases and tapered, subcapitate, or capitate apices, thin-walled, smooth, hyaline in KOH.

Artist’s Conk (Ganoderma applanatum) forms fruiting bodies that can persist for years, adding a new layer of pores annually. These show up as concentric rings, so you can estimate its age much like counting tree rings.

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.
