Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1
Classification: Plectosphaerellaceae, Glomerellales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Etymology: Refers to its similarity with Chloridium but with colored spore.
Mycelium composed of hyaline or pigmented hyphae. Teleomorph: Unknown. Anamorph: Lignicolous. Conidiophores pale brown, unbranched, macronematous, septate, terminated with conidiogenous cell, often with sympodial proliferation. Conidiogenous cells phialidic, integrated, subcylindrical, proliferating sympodially, geniculate, irregularly widened at the proliferations, dark brown and paler toward the tip, tapering slightly toward the collarette; collarettes funnel-shaped. Conidia oblong, ellipsoid, pale to medium brown, aseptate, truncate at the base, obtuse at the apex, arranged in wet spore heads.
Ecology/Substrate/Host: Saprobe on dead material of plant.
Geographical distribution: China, Surinam and USA.
Notes: The new genus Phaeochloridium is characterized by solidary, brown conidiophore with or without percurrent or sympodial proliferation, phialidic conidiogenous cells with funnel-shaped collarettes, and pale brown, ellipsoidal, cylindrical conidia with a darker hilum at the base. Morphologically it is similar to several genera such as Phialophora, Chloridium, Phaeoacremonium, but phylogenetically they belong to different families.
Type species: Phaeochloridium geniculata (Van Emden) W.P. Wu & Y.Z. Diao (≡ Phialophora geniculata Van Emden, Acta Bot. Neerl. 24:194, 1975).
Other accepted species: Species Fungorum – search Phaeochloridium.
