American mycologist.

David Arora (born October 23, 1952) is an American mycologist, naturalist, and writer. He is the author of two popular books on mushroom identification, Mushrooms Demystified and All That the Rain Promises and More.... Arora first developed an interest in wild mushrooms while growing up in Pasadena, California and organized his first mushroom collecting group while in high school. Later, an idea to start a mushroom club came about, and in 1984 he founded The Fungus Federation of Santa Cruz. He began teaching about wild mushrooms in the early 1970s while living in Santa Cruz, California. Arora

Butyriboletus regius (Royal Bolete) (Krombh.) D. Arora & J.L. Frank 2014
edible fungi species in the boletaceae family
Butyriboletus regius (formerly Boletus regius), commonly known as the royal bolete or red-capped butter bolete, is a basidiomycete species of fungus in the genus Butyriboletus. It has a pink cap, yellow flesh, and a reticulate pattern on the stem. The mushroom is found in North America, Europe, and China. North America specimens stain blue when exposed to air, but European specimens do not, or only stain weakly. Both are edible and considered choice.
Butyriboletus appendiculatus (Butter Bolete) (Schaeff.) D. Arora & J.L. Frank 2014
edible fungi species in the boletaceae family
Butyriboletus appendiculatus is an edible pored mushroom that grows under oaks and other broad leaved trees such as beech. It is commonly known as the butter bolete. It often grows in large colonies beneath the oak trees, and is frequently found cohabiting with old oaks in ancient woodland. It is relatively rare in Britain. Its stipe and pores are often bright yellow (hence its name of butter bolete) and its flesh stains bright blue when cut or bruised.
Butyriboletus fechtneri (Pale Bolete) (Velen.) D. Arora & J.L. Frank 2014
edible fungi species in the boletaceae family
Butyriboletus fechtneri is a basidiomycete fungus in the family Boletaceae. It was formerly regarded as a species of Boletus, but in 2014 was transferred to the newly erected genus Butyriboletus, after molecular data revealed that it is a member of the "Regius" clade (named after B. regius), quite distant from the core clade of B. edulis and closely allied species. Butyriboletus fechtneri is native to Europe, where it forms ectomycorrhizal associations with various broad-leaved trees of the family Fagaceae, particularly oak (Quercus), beech (Fagus) and chestnut (Castanea). So far it has been
Butyriboletus (Butter Boletes) D. Arora & J.L. Frank 2014
fungi genus in the boletaceae family
Butyriboletus is a genus of fungi in the family Boletaceae. The genus was circumscribed in 2014 by mycologists David Arora and Jonathan L. Frank to accommodate "butter bolete" species that were shown by molecular analysis to be phylogenetically distinct from Boletus. Butyriboletus contains 24 ectomycorrhizal species found in Asia, Europe, North America and north Africa. The group had earlier been classified as the section Appendiculati within the large genus Boletus. They were given the common name "butter boletes" as the color of their stalk, flesh and pores was similar to that of butter.

fungi species in the boletaceae family
Boletus rex-veris, commonly known as the spring king bolete, is a basidiomycete fungus of the genus Boletus found in western North America. The large, edible fruiting bodies known as mushrooms appear under pine trees, generally in May to June. It has a pinkish to brownish cap and its stem is often large and swollen, and the overall colour may have an orange-red tinge. As with other boletes, the size of the fruiting body is variable. Boletus rex-veris is edible, and may be preserved and cooked. For many years, Boletus rex-veris was considered a subspecies or form of the porcini mushroom B.
Caloboletus frustosus (Snell & E.A. Dick) D. Arora & J.L. Frank 2014
fungi species in the boletaceae family
Caloboletus frustosus is a bolete fungus native to North America. Until 2014, it was known as Boletus frustosus. Recent changes in the phylogenetic framework of the family Boletaceae prompted the transfer of this species, along with several other related boletes, including Caloboletus calopus, to the genus Caloboletus. It was first described scientifically in 1941 by mycologists Wally Snell and Esther Dick.
Butyriboletus abieticola (Mountain Butter Bolete) (Thiers) D. Arora & J.L. Frank 2014
fungi species in the boletaceae family

Boletus regineus (Queen Bolete) D. Arora & Simonini 2008
fungi species in the boletaceae family
Boletus regineus, commonly known as the queen bolete, is an edible and highly regarded fungus of the genus Boletus that inhabits southwestern North America. It was considered a variant of the similarly edible B. edulis for many years until declared a unique species in 2008. Phylogenetic analysis has shown B. regineus as a member of a clade, or closely related group, with B. subcaerulescens, Gastroboletus subalpinus, B. pinophilus, B. fibrillosus, and B. rex-veris. The cap is 5–18 cm (2–7 in) wide, convex then flat, brown with a whitish dusting when young. The stalk is 5–15 cm long, 3–6 cm
Rubroboletus haematinus (Mountain Satan's Bolete) (Halling) D. Arora & J.L. Frank 2015
fungi species in the boletaceae family
Rubroboletus haematinus is a fungus of the genus Rubroboletus. First described scientifically in 1976 by Roy Halling as a species of Boletus, in 2015 it was transferred to Rubroboletus, a genus circumscribed the year previously to contain other allied reddish colored, blue-staining bolete species. It is found in the western United States.
Craterellus calicornucopioides (California Black Trumpet) D. Arora & J.L. Frank 2015
fungi species in the hydnaceae family
Craterellus calicornucopioides is an edible fungus in the family Cantharellaceae. Described by David Arora and Jonathan L. Frank in 2015, is the North American version of the similar European species Craterellus cornucopioides. Molecular phylogenetics has shown that they are, however, distinct species. C. calicornucopioides associates with and fruits in the vicinity of oaks, manzanita, madrone, and Vaccinium.
Craterellus atrocinereus (Black Chanterelle) D. Arora & J.L. Frank 2015
fungi species in the hydnaceae family
Craterellus atrocinereus, commonly known as the black chanterelle or California black chanterelle, is a species of edible fungus native to western North America. This uncommon species is a mycorrhizal associate of live oak, tanoak, and Oregon white oak in Oregon and northern California, where it is found most often in the vicinity of Monterey Bay. This species has a "fruity-cheesy" odor, and fruits in winter and spring. This bluish-gray to black chanterelle was previously considered to be Craterellus cinereus but was recognized as a distinct species in 2015. The specific name is a nod to C.
Caloboletus marshii (Ben's Bitter Bolete) D. Arora, C.F. Schwarz & J.L. Frank 2014
fungi species in the boletaceae family
Caloboletus marshii, commonly known as Ben's bitter bolete, is a species of mushroom in the family Boletaceae. It is not poisonous, but it is too bitter to eat. It turns blue when cut or bruised, and it grows under live oak.
