Classification: Trichomeriaceae, Chaetothyriales, Chaetothyriomycetidae, Eurotiomycetes, Pezizomycotina, Ascomycota, Fungi

Isolated from marble stone or ornamental limestone. Sexual morph: Undetermined. Asexual morph: Colonies growing slowly, cauliflower-shaped, dark brown, velvety with irregularly lobate margin from above, black from below. Hyphae branched, pale brown, composed of simple to multiseptate, catenate cells produced by enteroblastic proliferation. Globose cells frequently produced intercalarly, terminarly or laterally, 1-multicellular, sometimes with endoconidia (Isola et al. 2016, Crous et al. 2019b).

Notes: Lithohypha Selbmann & Isola was introduced by Wijayawardene et al. (2017) to revise the illegitimate and unavailable name Lithophila Selbmann & Isola. Isola et al. (2016) introduced Lithophila Selbmann & Isola in Trichomeriaceae, which is a later homonym of Lithophila Sw., a name previously and validly published for a genus of Amaranthaceae. Lithohypha is characterized by slow growing, cauliflower-shaped colonies, branched, irregularly-shaped, simple to multiseptate, catenate hyphal cells and globose, dark cells generally enlarged to form multicellular bodies which probably function as resistance structures. Currently, L. aloicola Crous, L. catenulata L. Su et al. and L. guttulata Selbmann & Isola (type species) are included in this genus (Wijayawardene et al. 2017, Crous et al. 2019a, Sun et al. 2020). Phylogenetic analysis showed Lithohypha forms a sister group to Strelitziana and is aligned in Trichomeriaceae.

Type species: Lithohypha guttulata Selbmann & Isola, Fungal Diversity 86(1): 258 (2017).

Other accepted species: Species Fungorum – search Lithohypha.
