19 个国家在 24 种松属植物上报道了吉氏球腔菌，特别是幼苗和幼苗，其中包括 8 个国家和 5 个寄主的首次记录。 12 个国家的 10 种松属植物也报告了松球腔菌，特别是废弃的研究地块和废弃的种植园，其中包括尼泊尔、菲律宾、斯里兰卡和赞比亚的新记录。来自偏远原生蓝松林的 M. gibsonii 和 M. pini 以及来自尼泊尔原生 Chir 松林的 M. gibsonii 的记录表明，这两种真菌都是喜马拉雅地区以及中美洲的特有真菌。亚洲和非洲这些真菌生态型之间的差异表明，这两种真菌以不同的生态型存在于这些地区。
Sphaeropis sapinea 的记录证实其作为枝枯病病原体和兼性病原体在热带国家广泛存在；然而，M. Dearnessii 和针锈菌（Coleosporium spp.）的记录很少，表明这些真菌的传播不太容易实现。
Mycosphaerella gibsonii is reported from 19 countries on 24 Pinus spp., especially from seedlings and young plants, including first records for eight countries and five hosts. Mycosphaerella pini is also reported from 12 countries on 10 Pinus spp., especially from derelict research plots and abandoned plantations, including new records for Nepal, Philippines, Sri Lanka and Zambia. Records of M. gibsonii and M. pini from remote native blue pine forests and M. gibsonii from native Chir pine forests in Nepal suggest that both fungi are endemic to the Himalayan region as well as to Central America. Variation between ecotypes of these fungi from Asia and Africa suggests that both fungi are present in these regions as different ecotypes.
Records of Sphaeropis sapinea confirm its widespread occurrence as a shoot blight pathogen and as a facultative pathogen in tropical countries; whereas the paucity of records for M. dearnessii and needle rusts (Coleosporium spp.) suggests that spread of these fungi is less readily achieved.
