Campanophyllum was proposed as a new genus name to accommodate Lentinus proboscideus Fries.

A monotypic genus with gilled cyphelloid basidiomes. Morphological and DNA analysis along with mating experiments showed this taxon to be a separate and distinct genus (Cifuentes et al., 2003). Campanophyllum appears to be placed in the “/gloeostereae” clade where it is nested with Cheimonophyllum, Chondrostereum and Gloeostereum
On Wood, mostly oak and cloud forest, Mexico, Central America, Ecuador.

Endanreged under IUCN A4c criteria because of strong habitat past and future decline plus small population.

Campanophyllum proboscideum is an exclusively neotropical species with wide range from Mexico (Guerrero, Hidalgo, Michoacán, Oaxaca, State of Mexico, Tlaxcala, Veracruz), Colombia, Costa Rica, to Ecuador. A look-alike quite doubtful record from Buthan needs to be confirmed.

≤ 30 known localities, most finds in Mexico and Costa Rica.

It has been recorded from both temperate and cloud forest in the neotropics, habitat strongly threathened. Saprotroph, on unidentified hardwood, mostly veteran trees, some on alive trees.

Mexican and Central American temperate forests, associated with mountain chains; are among those preferred ecosystems for activities such as agriculture and animal husbandry. Therefore temperate areas are considered habitats that have been highly disturbed and they are most threatened and almost 30% have been deforested so far(Luna-Vega et al., 2006, Galicia and Gómez-García, 2010). Cloud forests are recognized as one of the most globally threatened plant communities because of their naturally scattered distribution along a narrow elevational belt in which intense land-use change continues.to take place. Around 60% of cloud forest trees are critically endargered to vulnerable and 50% of the original forest has been changed to other land uses (González-Espinosa et al., 2011, González-Espinosa et al, 2012).

We need to know plant hosts, the exact sizes of individuals and populations and the influence of nature conditions on fruiting.
