Mucronella is a genus of fungi in the family Clavariaceae. Species in the genus resemble awl-shaped teeth that grow in groups without a common subiculum (supporting layer of mycelium).

Taxonomy[edit]

The type species was originally named Hydnum calvum in a collaborative effort by the German botanist Johannes Baptista von Albertini and the American Lewis David de Schweinitz in 1805.[2] Swedish mycologist Elias Magnus Fries transferred the species to the newly described genus Mucronella in 1874.[3]

Molecular phylogenetic analysis suggests that the genus is monophyletic, and is sister to the remainder of the Clavariaceae,[4] confirming earlier suspicions that the taxa were phylogenetically related.[5] It had previously been placed in the Russulales due to its amyloid spores, and its morphological similarity to some members of genus Hericium.[4]

Description[edit]

Fruitbodies of Mucronella species resemble hanging spines; they occur singly, scattered, or in groups. Colors range from white to yellow to orange. Mucronella has a monomitic hyphal system —consisting of only generative hyphae. The basidia (spore-bearing cells) are four-spored and club shaped. Basidiospores are usually smooth with thin walls, weakly amyloid, and somewhat hyaline (translucent).[6] Mucronella is the sole genus in the Clavariaceae with amyloid spores, and with the "hanging spine" fruitbody morphology.[4]

Habitat and distribution[edit]

Mucronella species are saprotrophic.[4] Kartar Singh Thind and I.P.S. Khurana identified five species from the northwestern Himalayas, India, in 1974: M. bresadolae, M. calva, M. flava, M. subalpina, and M. pulchra.[6]

Species[edit]

Mucronella flava

As of August 2015, Index Fungorum accepts 17 species of Mucronella:[7]
